The present invention relates to a decom information conversion system, and more particularly, to a decom information conversion system and a decom information conversion method for converting medical image information into data in a decom format on a PC basis.

Conventionally, medical records are written or measured using an image viewer which is a PC (Personal Computer) based software. In addition, due to documenting and non-standardized data, there are many problems between data management and handling difficulties and compatibility.

With the aging of the population and the growth of economic needs, the increase in dependence on medical devices, the development of the Internet, telecommunications, and multimedia technologies have led to the connection of advanced electronic medical devices through networks, and the medical informatization project is underway worldwide. . However, with the advent of the Silver Society, each company's products have different specifications for video information, and several organizations have created DICOM (Digital Imaging and Communication in Medicine) transmission standards.

The DICOM standard defines data interchange protocols, digital image formats, and file structures for the transfer of medical images and their associated information to and from the hospital. The DICOM (hereinafter referred to as Decom) standard is a protocol for transferring medical images and related information between computers. The Decom 3.0 standard defines data interchange protocols, digital image formats, and file structures for the transfer of medical images and related information from inside and outside the hospital. The decom interface is then used for the interconnection of digital imaging devices.

On the other hand, PACS (Picture Archiving and Communication System) acquires digitized images directly from medical imaging equipments by taking pictures of patients in various medical imaging equipments and performs image reading through film, and transmits images through network. It is a system that can be directly read and stored on the screen. The introduction of this system has eliminated the need for hospitals for magnetic resonance imaging (MRI) and tomography (CT) films.

The PACS is composed of an acquisition subsystem, a storage subsystem, a database subsystem, a display subsystem, and a network subsystem connecting each subsystem. Here, the display subsystem is operated by PACS viewing software. Currently, a decom based PACS viewer is developed to extend the viewer function of the PACS to add a new function according to a user's request.

By the way, the decompression image can be viewed by the viewing software in the PACS system, but the PACS system itself is expensive, so the burden on the hospital and medical personnel is high. In addition, in the related art, it is not possible to transmit decom information or search for decom information on a personal computer (PC) basis.

Accordingly, the present invention has been made in order to solve the above problems, it is necessary to store the image of the affected area in a PC that does not support the decom standard image and stored and stored as medical image information along with pre-input patient information and shooting information Accordingly, an object of the present invention is to provide a decom information conversion system and a decom information conversion method for converting image and medical image information into a decom format.

The present invention for achieving the above object, in the PC-based decom information conversion system having a camera connection, capture image acquisition / processing unit for capturing and collecting the image input from the camera connection, and the capture image collection / A capture image compression unit for compressing the captured image output from the processing unit, a storage unit, and a program executed when inputting image data from the camera to control the capture image collection / processing unit to obtain a captured image, and the compressed captured image It is assigned to the identification number to store in the storage unit as the medical image information with the pre-input patient information, and if the decompression information request signal of a predetermined patient is input, retrieves and reads the medical image information of the requested patient in a decom format It is month by including decom information conversion retrieval unit which functions to convert It is.

Meanwhile, according to another aspect of the present invention, a PC-based decom information conversion method having a camera connection, comprising: generating a captured image by capturing an image input from the camera connection; Storing the captured image as medical image information; Receiving a decom information conversion request; Searching for and reading the requested medical image information; And by converting the read medical image information into a decom format.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a PC (personal computer) based decom information conversion system according to the present invention, Figure 2 is an internal configuration diagram of the capture image acquisition / processing unit of Figure 1, Figure 3 is a capture image compression unit of Figure 1 The internal configuration diagram.

The present invention provides a function of converting and transmitting a captured image into a decom format when requesting decom information through a keyboard (not shown) through a PC or requesting decom information from an external medical imaging apparatus through a network, and searching and displaying decom information. To implement a system that has the capability to

PC-based decom information conversion system for the function, as shown in Figure 1, to collect and process the camera (1) for taking an image, and the image (NTSC or PAL standard) taken by the camera (1) Capture image acquisition / processing unit 10, Capture image compression unit 20 for compressing the captured image using JPEG (Joint Photograph Expert Group) compression format, and Decom which is software for searching and converting medical image information into decom format. An information conversion and retrieval unit 30, a central processing unit 4 for executing the decom information conversion and retrieval unit 30, and a display unit 3 for displaying the retrieved decom information and images. Here, the display unit 3 includes a PC monitor or an LCD (Liquid Crystal Display) device.

As shown in FIG. 2, the captured image acquisition / processing unit 10 may convert the image signal input from the camera 1 into a digital image signal, and pattern the digitized image. It is a printed circuit board comprised of the digital pattern generation part 13 and the digital pattern capture part 15 which captures the digital pattern processed image.

As illustrated in FIG. 3, the captured image compression unit 20 includes a two-dimensional DWT 21, a quantization unit 22, a context extractor 23, and an arithmetic encoding. It consists of an Arithmetic Coder 24 to compress the captured image in JPEG format. Since the compression method of the JPEG format is a known technique, the configuration of each block is briefly described. Since medical images have a large data size, data transmission efficiency can be increased by compressing the data.

Two-dimensional DWT (Discrete Wavelet Transform) (21) is a DPCM (Differential Pulse) to find the redundancy of the information in the captured image (tomographic image, transmission image, general image) output from the capture image acquisition / processing unit 10 Code Modulation) is performed.

The quantization unit 22 reduces the number of significant digits by dividing the value obtained through the DPCM by a predetermined constant.

The context extractor 23 performs Run Length Coding (RLC), Zero Coding (ZC), Sign Coding (SC), and Magnitude Refinement Coding (MRC) to extract context.

Arithmetic Coder 24 performs entropy coding based on the extracted context. Arithmetic coding does not assign one codeword to a data value, but rather reduces the number of bits by determining the codeword for the entire data using the probability value of the data itself.Entropy coding uses non-uniform statistical probability of the data. An encoding method for compressing data.

The image input from the camera 1 is captured by the captured image collecting / processing unit 10 and then compressed by the captured image compression unit 20 to the JPEG codec.

In the captured image collecting / processing unit 10, the digital pattern capturing unit 15 captures a still image at 6 frames per second, for example, on a maximum of one screen, for example, up to 6 sheets at 320 × 240 size. Configure the screen to show on the (not shown).

The decom information conversion and retrieval unit 30 includes a medical image information storage unit 31, a medical image information retrieval unit 32, a decom format conversion unit 33, a medical image information viewer interface generator 34, , Which is a kind of software (hereinafter referred to as a decom information conversion program) configured by the network processing unit 35, stores a medical image information, and detects a decom information request through a keyboard (not shown) or an external medical image through a network. It detects request for decom information from device and converts it to decom format.

The decom information converting and searching unit 30 controls the captured image collecting / processing unit 10 and the captured image compressing unit 20 to capture and compress the captured image. Then, an identification number is assigned to each compressed image and stored in a storage unit (for example, a hard disk, etc.) together with previously stored patient information, and the decom information is retrieved and displayed according to a request from the outside. Function Here, the medical image information further includes test information, photographing information, and test device information.

The medical image information storage unit 32 assigns an identification number such as 00001.jpg, 00002.jpg, ... to the captured image when storing the image captured by the captured image collection / processing unit 10. In addition, the medical image information storage unit 32 generates a subfolder having a file name (for example, MDI20040310) for the date of photographing for convenience of storage and retrieval, and stores the captured image in the generated subfolder. In this case, the lower folder is preferably stored in an upper folder whose file name is a newly generated or previously stored patient identification number at the time of image capture. In the upper folder, medical image information including captured image information, pre-input patient information, examination information, imaging information, and examination device information is stored in the form of a text file (imageinfo.ini). The patient information, the examination information, the imaging information, and the examination device information may be input through a decom information detailed interface displayed by selecting a desired decom information viewer on the decom information viewer selection interface screen of FIG. 9 to be described later.

According to the present invention, when storing the medical image information, the medical image information storage unit 32 does not store the patient information and the captured image in a decom format, and selects a separately provided decom conversion function in a decom format. It is desirable to convert and save.

The medical image information retrieval unit 32 functions to retrieve medical image information.

The decom format converter 33 converts the medical image information into a decom format for data transmission.

The medical image information viewer interface generating unit 34 functions to generate a viewer and a search interface for decom information (patient information, inspection information, photographing information, inspection device information, image information, etc.). To this end, the decom information conversion program defines the format of the decom image information as an information object definition (IOD).

Information Object Definition (IOD) is a format for entering data in a form such as a resume. That is, only the data types are listed and the place where the actual data is to be entered is left blank. When actual data is input in this IOD format, it is called Information Object Instance (IOI). In the present invention, the IOD includes patient information, examination information, photographing information, image information, and the like, and is stored in the form of a text file.

The network processor 35 receives a decom information request from a remote or local decom based medical imaging apparatus and transmits the converted decom data. The decom specifies the operation in a standard network environment, and defines the form for exchanging data with each other. Therefore, the network processor 35 transmits and receives medical image data in a decom format using a decom standard.

4 is a configuration diagram of the decom information table 40 of FIG. 1. When decom information is stored in PC, its own storage library is configured for quick data processing.

In operation S2, an image input through the medical image capture screen 50 of FIG. 7 is captured by digital pattern processing.

Each captured image captured by the captured image compression unit 20 is compressed in step S3. In step S4 stores the captured image compressed by the patient identification number (for example, registration number) in the storage unit (for example, hard disk). In step S5, when the decom information is requested through the network or stored in a portable storage unit (for example, a USB storage device), it detects whether a decom conversion request occurs. As a result of the determination in step S5, if there is a request for decom information, it is determined in step S6 whether a captured image of the patient exists. If the captured image exists in step S6, the data element of the transport packet according to the decom format is generated with reference to the decom information table 40 in step S7. The data element generated in step S8 is transmitted through a network.

As such, when there is a need to transmit the decom information, the medical image information corresponding to the patient information to be read is read and converted into a decom packet to be transmitted.
