Description

  Embodiments described herein relate generally to an image management server and an image management method.

  In recent years, a system called a medical image information system (PACS: Picture Archiving and Communication System) for managing a photographed image of a subject has been introduced in hospitals and laboratories.

  This medical image information system receives image data captured by an image capturing device (also referred to as a modality), and stores a database, NAS (Network Attached Storage), DAS (Data Attached Storage), USB hard disk, SAN ( The image data is stored in a storage area network or the like. The medical image information system has a function of searching for specific image data in response to a request from a client such as an image viewer or an image interpretation device and transferring the searched image data to the client side.

  By the way, when acquiring image data and storing the image data in a database, NAS, or the like, an image processing apparatus that determines a storage destination for storing the image data according to the remaining capacity of the storage destination is known ( For example, see Patent Document 1).

JP 2010-74307 A

  For example, when the image processing apparatus described above determines the storage destination of the image data, if the information on the free capacity of the storage area of the storage apparatus that stores the image data is acquired and the storage destination is determined, the free capacity in the storage area is determined. The storage destination is determined by concentrating on the largest storage device. In this case, if a plurality of pieces of image data are read out in order to compare the image data on the viewer, the plurality of pieces of image data are read out from the same storage device, and the processing capability may be reduced.

  That is, when a read process is performed on a plurality of image data stored in the same storage device, a process for reading the image data from the storage device is performed on the plurality of image data. In some cases, it takes a long time to display the image data on the viewer.

  In order to solve the above problem, the image management server according to the present embodiment stores a request reception unit that receives a request to store a captured image, and shooting information that stores the shooting information of the first captured image that has received the storage request. If the file capacity of the information storage unit and the captured second captured image associated with the captured information of the first captured image is equal to or greater than the threshold value assigned to the file capacity, the second captured image A storage destination determination unit that determines an image data storage unit different from the image data storage unit in which the image is stored as a storage destination of the first captured image; and a first captured image that has received the storage request. A data transmission / reception unit that receives and transmits the first captured image to the determined image data storage unit;

(First embodiment)
Hereinafter, a medical image management system 600 including the image management server 200 according to the present embodiment will be described with reference to the accompanying drawings. In the present embodiment, the medical image management system 600 will be described with an embodiment including an image capturing device and a medical image information system (PACS: Picture Archiving and Communication System).

  FIG. 1 is a schematic configuration diagram illustrating a schematic configuration of a medical image management system 600 including an image management server 200 according to the first embodiment.

  As shown in FIG. 1, a medical image management system 600 includes a modality MA 100, a modality MB 110, an image management server 200, a NAS (Network Attached Storage: image data storage unit) 300, a NAS 310, a NAS 320, an image interpretation device 400, a viewer 500, and the like. It is prepared for.

  Modality MA100, modality MB110, image management server 200, NAS300, NAS310, NAS320, image interpretation device 400, and viewer 500 are each connected to network 550.

  Modality MA100 and modality MB110 are image capturing devices for capturing a subject. Examples of the imaging apparatus include an X-ray CT (Computed Tomography) apparatus, an MRI (Magnetic Resonance Imaging) apparatus (magnetic resonance diagnostic apparatus), an ultrasonic diagnostic apparatus, and a nuclear medicine diagnostic apparatus.

  An X-ray CT apparatus is an imaging apparatus that scans an object using radiation or the like and processes it using a computer. An MRI apparatus is an apparatus that captures an image of the inside of a subject using a magnetic field and radio waves. The ultrasonic diagnostic apparatus is an image diagnostic apparatus that applies ultrasonic waves to a subject and visualizes the echoes. A nuclear medicine diagnostic device labels a reagent that accumulates in a specific lesion injected into a subject with a radioisotope, and detects γ-rays emitted from the reagent with a detector such as a scintillation camera. Thus, the diagnostic imaging apparatus extracts a tomographic image of a human body including a lesion. In the present embodiment, any modality can be applied as appropriate.

  The modality MA 100 and the modality MB 110 are connected to the image management server 200, NAS 300, NAS 310, NAS 320, the image interpretation device 400, and the viewer 500 via the network 550.

  The image management server 200 is a server that stores, browses, and manages image data photographed by the modality MA 100 or modality MB 110. In particular, in the present embodiment, control is performed to store image data acquired from the modality MA 100 or modality MB 110 in the NAS 300, NAS 310, NAS 320, or the like via the network 550.

  The NAS 300, NAS 310, and NAS 320 are single-function servers in which a hard disk, a network interface, and the like are integrated. In the present embodiment, the NAS 300, the NAS 310, and the NAS 320 receive an instruction to store image data from the image management server 200, and store the image data in the hard disk of each NAS. In the NAS 300 to NAS 320, when it is not necessary to specify any one as the image data storage unit, it is simply described as NAS.

  The image interpretation apparatus 400 is an apparatus that interprets image data stored in the NAS 300, NAS 310, and NAS 320 to create findings and approves the created findings.

  The viewer 500 is an examination report display terminal carried by the doctor in charge or a report display terminal that displays an examination report in the examination room. The viewer 500 receives image data stored in the NAS 300, NAS 310, and NAS 320 and displays the image data.

  The network 550 is a network for connecting the image management server 200, the NAS 300, the NAS 310, the NAS 320, the image interpretation device 400, and the viewer 500 that constitute the medical image information system.

  FIG. 2 is a functional block diagram illustrating functions of the image management server 200 according to the first embodiment.

  As shown in FIG. 2, the image management server 200 includes a request reception unit 210, a shooting information storage unit 220, a storage destination determination unit 230, and a data transmission / reception unit 240.

  The request accepting unit 210 accepts a request (storage request) for storing image data (captured image) from the modality MA 100 or modality MB 110 via the network 550. Specifically, a request for storing image data shot by modality MA100 is received, and shooting information corresponding to the image data is acquired. Then, the request reception unit 210 sends the shooting information to the shooting information storage unit 220.

  The shooting information storage unit 220 stores shooting information corresponding to the image data for which the request reception unit 210 has received the storage request. The details of the shooting information will be described later.

  The storage destination determination unit 230 is configured to determine the storage destination of the storage target image data (first captured image) for which the request reception unit 210 has received the storage request. Specifically, it is confirmed whether or not the previous image data for comparison (second captured image) that has been photographed associated with the photographing information of the image data to be stored is present, and the file capacity of the previous image data for comparison is greater than or equal to the threshold value. In this case, the storage target image data is determined to be stored in a NAS (for example, NAS 310 or NAS 320) different from the NAS (for example, NAS 300) in which the comparison previous image data is stored.

  More specifically, when a captured image of a subject is received from the modality MA 100, the storage location determination unit 230, based on the imaging information of the image data captured by the modality MA 100, previously compared previous image data ( It is determined whether or not (image data to be compared) is stored in the NAS.

  Here, when the comparison previous image data is stored in any NAS and the file size of the comparison previous image data is equal to or larger than the file capacity threshold of the image data, the storage destination is determined. The unit 230 stores the image data to be saved corresponding to the storage request received by the request reception unit 210 in a NAS different from the NAS in which the previous image data for comparison is stored.

  For example, when the file capacity threshold of image data captured by X-ray CT is set to 1 GB, the file capacity of image data (second captured image captured) captured by X-ray CT Is 2 GB, the storage target image data is stored in a NAS (storage destination) different from the NAS in which the 2 GB image data is stored.

  Note that the threshold of the file capacity of the image data can be provided for each type of photographing method. For example, a predetermined threshold value can be set, such as 1 GB or more in the case of X-ray CT inspection, 3 GB or more in the case of MRI inspection, and 500 MB or more in the case of ultrasonic inspection. The file capacity threshold can be arbitrarily set and changed according to a shooting location (shooting location), shooting conditions, or order information, which will be described later.

  As a result, when the file capacity of the image data is equal to or greater than a predetermined threshold, the storage target image data to be stored is stored in a NAS that is different from the NAS in which the previously captured comparison previous image data is stored. Therefore, it is possible to prevent the throughput from being lowered when reading the two image data simultaneously.

  Further, the image data to be stored and the previous image data for comparison are not limited to the same imaging method. For example, X-ray CT image data and ultrasound image data are compared as different imaging methods. The MRI image data and the X-ray CT image data may be compared.

  In this case, for example, a combination of different shooting methods is set in advance, and the image data to be stored is compared with the previous image for comparison based on the file capacity threshold of the image data corresponding to the shooting method and the file size of the previous image data for comparison. The data can be stored in a NAS different from the NAS in which the data is stored, that is, the NAS in which the previous image data for comparison is not stored.

  As an example, X-ray CT image data and ultrasound image data are compared, and the file capacity threshold of image data corresponding to ultrasound is set to 500 MB in advance. In this case, if the file size of the previous image data for comparison taken with ultrasound is 800 MB, the file size of the previous image data for comparison exceeds the threshold value, so the storage destination determination unit 230 uses the X-ray CT. The storage destination of the image data to be stored captured in step (1) is determined to be a NAS that does not store the previous image data for comparison captured by ultrasound.

  In this case, it is not always necessary to consider the file capacity of the image data, and the storage location of the image data may be determined based only on a combination of different shooting methods.

  Further, the storage target image data can be associated with a plurality of comparison previous image data. That is, when any file capacity of the previous image data for comparison is greater than or equal to a predetermined threshold, the storage destination determination unit 230 stores the image data to be saved in the NAS in which the previous image data for comparison is stored. By avoiding this, the image data to be saved can be stored in a NAS different from the NAS in which the previous image data for comparison is stored.

  The data transmission / reception unit 240 receives the storage target image data corresponding to the storage request received by the request reception unit 210, and transmits the storage target image data to the NAS determined by the storage destination determination unit 230. Yes.

  As described above, the image management server 200 according to the present embodiment, based on the shooting information of the storage target image data for which the storage request has been received, includes the previous image data for comparison that was previously shot based on the shooting information. When the comparison image data is equal to or greater than a predetermined threshold, the storage target image data is stored in a NAS different from the NAS in which the comparison previous image data is stored.

  FIG. 3 is a hardware block diagram illustrating a hardware configuration of the image management server 200 according to the first embodiment.

  As shown in FIG. 3, the image management server 200 includes a central processing unit (CPU) 250, a read only memory (ROM) 252, a random access memory (RAM) 254, a network interface unit 256, an operation input unit 258, and a display unit 260. A storage unit 262, an internal bus 264, and the like.

  The CPU 250 can implement the functions of the various programs by loading the various programs stored in the ROM 252 into the RAM 254 and expanding the programs. The RAM 254 is used as a work area (working memory). The ROM 252 stores various programs. Various programs stored in the ROM 252 include programs for realizing various functions shown in the image management server 200 (FIG. 2).

  The network interface unit 256 is an interface unit for receiving image data (Rawdata) from the modality MA 100 or modality MB 110 via the network 550 or transmitting image data to the NAS 300 or NAS 310.

  The operation input unit 258 is an input device for adding information to or editing the shooting information related to the storage target image data received from the modality MA 100 or the modality MB 110. The operation input unit 285 is configured with a keyboard, a mouse, and the like.

  The display unit 260 displays shooting information related to image data. For example, it is a display device for displaying inspection conditions, order information, or incidental information, which will be described later. This display unit is configured by a liquid crystal display, a monitor, or the like.

  The storage unit 262 is a storage unit that constitutes a storage memory, and includes a RAM, a hard disk, and the like. For example, the storage unit 262 constitutes the photographing information storage unit 220.

  The internal bus 264 is connected to each component so that the CPU 250 performs overall control of the entire image management server 200.

  Next, imaging information received by the request reception unit 210 of the image management server 200 according to the first embodiment will be described. In the present embodiment, the case where the DICOM (Digital Imaging and Communications in Medicine) standard used in PACS is used will be described. However, the present invention is not limited to the DICOM standard.

  FIG. 4 is an explanatory diagram illustrating an example of the shooting information 221 received by the request reception unit 210 of the image management server 200 according to the first embodiment.

  As illustrated in FIG. 4, the shooting information 221 is described as information related to the storage target image data in the metadata of the storage target image data.

  Specifically, “bell # 1” is described in “patient name” of the imaging information 221. “Patient ID” (ID: identifier) describes “P2012040A”. The “patient birth date” is described as “February 2, 1990”. The “inspection UID” (UID: Unique Identifier) describes “P12.34.567.89”. In the “imaging method”, “X-ray CT” is described. In “imaging conditions”, “waist” is described. The “order information” describes “modality MB110”. Further, “Series 12.34.5” is described in “Series UID” (UID: Unique Identifier).

  This imaging information 221 is described as “MRI” when the imaging method of the image data is taken by another method, for example, when the imaging method is taken by “MRI”, and the imaging condition is also “pulse sequence. "Setting" etc. are described.

  Also, the imaging condition is not limited to “lumbar region”, but the imaging target region that is the imaging condition such as “cervical vertebra” and “hip joint” is described. Further, for example, “tube current, tube voltage, application time, application timing” may be described as the X-ray irradiation conditions.

  The order information means a specific request content that the doctor in charge gives an instruction to the laboratory technician, for example, the name of the inspection apparatus instructed by the doctor in charge, patient information, imaging time, imaging location, diagnostic part Information relating to shooting including can be included.

  The series UID means a series of image data names obtained by photographing. The “UID” described above means a unique ID number used in the DICOM system.

  Further, since the shooting information 221 is attached to the header portion of the image data, additional information can be attached. For this reason, the attending physician can include patient's disease name, past medical history, prescription drugs, contents of contrast examination, meal management, and the like as incidental information.

  Thus, the shooting information 221 according to the present embodiment can be associated with any one of these items.

  Next, in the medical image management system 600 including the image management server 200 according to the present embodiment, when the image management server 200 acquires image data from the modality MA 100, the image data is stored in any NAS. The procedure of the storage process will be described. As an example, image data associated with a patient ID is a search target.

(Image data storage processing)
FIG. 5 is a flowchart illustrating an image data storage processing procedure in which the image management server 200 according to the first embodiment determines a storage location of image data and stores the image data in the determined storage location. In FIG. 5, reference numerals with numerals added to S indicate steps of the flowchart.

  First, the request reception unit 210 acquires a storage request for image data (saved target image data) taken by the modality MA 100 (or modality MB 110) via the network 550 (step S001).

  The request reception unit 210 stores the shooting information corresponding to the acquired image data of the storage request in the shooting information storage unit 220 (step S003). In addition, the request receiving unit 210 sends the shooting information of the image data to be saved to the storage destination determining unit 230.

  The storage destination determination unit 230 selects any one of the previous image data for comparison (second photographed image) that has been photographed associated with the photographing information (patient ID) of the storage target image data (first photographed image). It is determined whether it is stored in NAS (step S005).

  When there is comparison previous image data associated with the shooting information (patient ID) of the storage target image data (YES in step S005), the storage destination determination unit 230 compares the shooting information with the shooting information of the storage target image data. The shooting information of the previous image data is compared to determine whether comparison is possible (step S007).

  For example, when the patient ID is the same, or when the patient ID and the imaging method, and the patient ID and the imaging conditions match, the storage destination determination unit 230 can compare the storage target image data with the previous image data for comparison. A determination is made (YES in step S007), and a threshold is determined for the file capacity of the previous image data for comparison (step S009).

  If the file size of the previous image data for comparison is greater than or equal to a predetermined threshold (YES in step S011), the storage destination determination unit 230 stores the file in a NAS different from the NAS in which the previous image data for comparison is stored. The storage destination is determined so as to store the target image data. Then, the data transmitting / receiving unit 240 receives the storage target image data corresponding to the storage request, transmits the storage target image data to the NAS determined by the storage destination determination unit 230, and stores it (step S013).

  For example, when the storage destination determination unit 230 receives a storage request for imaging information (FIG. 4) with the patient ID “P20120401A”, the “imaging method” and “imaging condition” captured for this patient ID have the same contents. When data (previous image data for comparison) exists in any NAS and the file capacity of the previous image data for comparison is equal to or larger than a predetermined threshold, the NAS (for example, the previous image data for comparison is stored) , NAS 300), the storage target image data is stored in a NAS (for example, NAS 310 or NAS 320) different from NAS 300).

  In step S007, the determination as to whether or not the previous image data for comparison is the comparison target in the comparison of the imaging information is not limited to the case where the patient IDs are the same. Even if the X-ray CT is the same and the imaging location indicated by the imaging condition is different, the previous image data for comparison can be obtained. If the imaging location indicated by the imaging condition is the same, the imaging method is “X-ray CT”. Even if the CT and the MRI are different, if the patient ID is the same, it can be determined as the previous image data for comparison. Details will be described in the second embodiment.

  On the other hand, the storage destination determination unit 230 determines that the image data to be stored is not comparable with the previous image data for comparison (NO in step S007), or the file capacity of the previous image data for comparison is less than a predetermined threshold. (NO in step S011), the image data to be stored is stored in one of the NAS 300, NAS 310, or NAS 320 according to the free space of the NAS (step S015).

  In this case, the data transmitting / receiving unit 240 receives the storage target image data corresponding to the storage request, transmits the storage target image data to the storage destination determined according to the free space of the NAS, and stores it (step S015). ).

  If there is no comparison previous image data associated with the imaging information (in this case, the patient ID) of the image data to be stored (NO in step S005), the storage destination determination unit 230 sets the free space of the NAS. In response, the image data to be saved is stored in one of the NAS 300, NAS 310, or NAS 320 (step S015).

  Note that in the case of NO in step S005, since there is no captured previous image data for comparison, it can be estimated that the patient is a new patient, so that it is stored in any NAS according to the free space of the NAS. It has become.

  In step S011, if the file capacity of the previous image data for comparison is smaller than a predetermined threshold (NO in step S011), the image data to be saved is temporarily stored in the same NAS as the NAS in which the previous image data for comparison is stored. Even if it is stored, the throughput does not decrease, so that it can be stored in any NAS according to the free space of the NAS.

  Thus, in the present embodiment, when the data transmission / reception unit 240 stores the image data to be saved in the NAS (steps S013 and S015), the image data storage process ends.

  As described above, the image management server 200 according to the present embodiment selects the image data to be stored that has received the storage request according to the file size of the previous image data for comparison that was previously captured. Is stored in a NAS different from the NAS in which is stored.

  Thereby, the image management server 200 according to the present embodiment stores the storage target image data and the comparison previous image data in different NASs according to the file capacity of the comparison previous image data stored in the NAS. Therefore, it is possible to prevent the throughput from being lowered when reading the two image data at the same time.

(Second Embodiment)
In the first embodiment described above, the same patient ID (same subject) in the imaging information is searched, the file capacity threshold value of the previous image data for comparison previously captured is determined, and the image to be stored The storage location of the data is controlled to be different from the storage location of the previous image data for comparison.

  In the second embodiment, even if the patient ID in the imaging information for which the storage request has been received is different from the patient ID of the previous image data for comparison, if the same examination method and the same imaging conditions are used, a different subject is used. Even if it exists, control is performed so that the image data to be stored and the previous image data for comparison are stored in different NAS.

  In this case, since the image management server 200 according to the present embodiment can store the image data of the subject to be compared in different NAS, the image management server 200 performs the reading process of the image data of the subject to be compared. In this case, it is possible to prevent a decrease in throughput.

  For example, search for imaging information having the same imaging method and imaging conditions, and store image data to be stored in a NAS different from the previous image data for comparison for image data that may be compared even if the subject is different. Or by arbitrarily combining the previous image data for comparison, which can be a comparison target, with various combinations of imaging methods, imaging conditions, or order information.

  As a result, it is possible not only to read out the image data of the patients without reducing the throughput, but also to quickly compare the image data of the affected area between the patient and the normal person.

(Third embodiment)
In the first embodiment described above, when the file size of the previous image data for comparison is greater than or equal to a predetermined threshold (YES in step S011 in FIG. 5), the image management server 200 stores the previous image data for comparison. Although the image data to be saved is stored in a NAS different from the NAS (step S013), the present invention is not limited to this.

  FIG. 6 is a flowchart illustrating an image data storage processing procedure in which the image management server 200 according to the third embodiment stores image data.

  The flowchart shown in FIG. 6 is different from the flowchart of FIG. 5 in that step S101 is added. Other than that, it is the same as the flowchart of FIG.

  In step S101 shown in FIG. 6, the storage location determination unit 230 determines that the shooting date recorded in the shooting information of the image data to be saved is a predetermined value from the last shooting date recorded in the shooting information of the previous image data for comparison. It is further determined whether or not it is within the period.

  Specifically, when the file size of the previous image data for comparison is greater than or equal to a predetermined threshold (YES in step S011), the image management server 200 captures the photographing date (examination date) recorded in the photographing information of the storage target image data. Is compared with the shooting date (inspection date) recorded in the shooting information of the previous image data for comparison (step S101).

  When the shooting date of the storage target image data is within a predetermined period from the shooting date of the last previous comparison image data (YES in step S101), the storage destination determining unit 230 stores the storage target image data. Then, it is stored in the determined NAS (step S013).

  On the other hand, when the shooting date of the storage target image data has passed a predetermined period or more from the shooting date of the last image data for comparison (NO in step S101), the storage destination determination unit 230 The image data to be saved is stored in one of the NASs according to the free space of the NAS (step S015).

  For example, in the case where the previous image data for comparison previously captured by X-ray CT was three years ago, it is not necessary to compare the captured content of the previous image data for comparison with the captured content of the image data to be stored. Since it is assumed, the image management server 200 determines the storage destination of the image data to be saved according to the free space of the NAS.

  In this case, the predetermined period from the last imaging can be arbitrarily set for each patient or for each symptom such as a period of 6 months as a regular check-up or one year as a follow-up.

(Fourth embodiment)
In the first to third embodiments described above, when the storage destination of the storage target image data is determined, the image management server 200 stores the storage target image data as it is in the determined storage destination. However, the present invention is not limited to this.

  For example, the image management server 200 may temporarily change the storage destination of the storage target image data in accordance with the operation status of the NAS that is the storage destination of the determined storage target image data. That is, the image management server 200 temporarily stores the image data to be saved in another NAS according to the NAS operating status, and after the determined NAS operating status is stabilized, the image management server 200 stores the image data to be determined. You may make it store preservation | save object image data.

  For example, when the operation status of the NAS 310 determined as the storage destination is in a “BUSY state” due to concentration of access from other devices, the image management server 200 temporarily sets the storage destination of the storage target image data. Thus, the storage target image data is stored in the NAS 320. Then, the operational status of the NAS 310 is determined again, and when the “BUSY state” is resolved, the image management server 200 may move the image data to be stored stored in the NAS 320 to the NAS 310.

  In addition, the image management server 200 according to the present embodiment may periodically change the storage location of the previous image data for comparison in accordance with the free space of the NAS, and consider NAS load distribution. The storage location can be changed as appropriate.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.

  Further, in the embodiment of the present invention, each step of the flowchart shows an example of processing that is performed in time series in the order described. The process to be executed is also included.
