In order to make the technical scheme and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description is intended to illustrate the invention and is not intended to limit the scope of the invention.
For simplicity and clarity of description, the following description sets forth aspects of the invention by describing several exemplary embodiments. Numerous details in the embodiments are provided solely to aid in the understanding of the invention. It will be apparent, however, that the embodiments of the invention may be practiced without limitation to these specific details. Some embodiments are not described in detail in order to avoid unnecessarily obscuring aspects of the present invention, but rather only to present a framework. Hereinafter, "comprising" means "including but not limited to", "according to … …" means "according to at least … …, but not limited to only … …". The term "a" or "an" is used herein to refer to a number of components, either one or more, or at least one, unless otherwise specified.
The applicant found that: in the prior art, there are many areas for improvement due to the reliance on PACS to obtain DICOM files. The embodiment of the invention provides a technical scheme for independently acquiring DICOM files without depending on PACS.
FIG. 1 is a flow chart of a method for obtaining a DICOM file in accordance with an embodiment of the invention. The method is suitable for execution by a device that obtains DICOM files that is not included in PACS.
As shown in fig. 1, the method includes:
step 101: and obtaining the copy data packet of the data packet provided by the data copy equipment and sent by the medical image equipment.
Here, the medical imaging device refers to various instruments for reproducing structures inside a human body as images by using various media as information carriers, and the image information has a spatial and temporal distribution correspondence with the actual structures of the human body. For example, the medical imaging device may include an X-ray device, a CT device, a magnetic resonance device, an ultrasound device, and the like. The medical imaging device may generate a DICOM file and encapsulate the DICOM file into data packets based on a predetermined transmission protocol (e.g., TCP/IP protocol or CAN protocol, etc.), and send the data packets out, such as to a PACS system, via a data exchange device (e.g., a switch or router, etc.) coupled to the medical imaging device.
While the above exemplary embodiment of a medical imaging device has been described, those skilled in the art will recognize that this description is exemplary only and is not intended to limit the scope of embodiments of the present invention.
And the data copying device is used for copying the data packet generated by the medical image device. In step 101, the apparatus for obtaining the DICOM file may obtain the copy data packet of the data packet sent from the medical imaging device from the data copy device.
In one embodiment, at a network TAP disposed between the medical imaging device and the data exchange device, a duplicate data packet is generated based on the data packet sent by the medical imaging device; the duplicate packets are obtained from the network TAP.
In particular, the data replication device may be embodied as a TAP arranged between the medical imaging device and the data exchange device. The input port of the TAP is connected with the medical imaging device to receive the data packet sent by the medical imaging device. The network TAP generates a duplicate data packet based on the data packet sent by the medical imaging device. Furthermore, the network TAP has two output ports, one of which is connected to the data exchange device to send the data packet sent by the medical imaging device to the data exchange device, so that the data packet is sent out by the data exchange device, for example, to the PACS system; the other output port is connected to the device for obtaining the DICOM file, thereby sending the copy data packet to the device for obtaining the DICOM file.
It can be seen that duplicate data packets of data packets sent by the medical imaging device can be conveniently generated by means of a network TAP arranged between the medical imaging device and the data exchange device.
In one embodiment, a data packet sent by a medical imaging device is sent to a PACS via a first port in a data exchange device connected with the medical imaging device; and acquiring a copy data packet of the data packet sent by the medical image equipment through the mirror image port of the first port.
The data copying device may be implemented as a port mapping (port Mirroring) capable data exchange device arranged in connection with the medical imaging device. The input port of the data exchange device is connected with the medical image device to receive the data packet sent by the medical image device. Furthermore, based on the port mirroring function of the data switching device, data traffic of one or more source ports on the data switching device may be forwarded to a designated port to effect interception of the network, wherein the designated port is referred to as a mirrored port. The data switching device may be embodied as a switch or router, etc.
Specifically, the data exchange device is provided with an input port for receiving a data packet sent by the medical imaging device. The data exchange device is provided with two ports (both output ports), wherein the first port is connected with the PACS to send data packets sent by the medical image device to the PACS system; the second port is a mirrored port of the first port. The mirror port is coupled to the device for obtaining the DICOM file to send the replicated data packets of the data packets output via the first port to the device for obtaining the DICOM file.
Step 102: when a predetermined DICOM file feature is detected from the duplicate data packet, the DICOM file is extracted from the duplicate data packet.
In one embodiment, detecting the predetermined DICOM file characteristic from the duplicate data packet includes at least one of:
(1) A DICOM prefix equivalent to the first predetermined character is detected from the duplicate data packet.
Therefore, the DICOM file can be conveniently identified by detecting the DICOM prefix.
(2) A DICOM prefix equivalent to a first predetermined character and a data type field equivalent to a second predetermined character are detected from the duplicate data packet.
Therefore, the embodiment of the invention can accurately identify the DICOM file through the comprehensive detection of the DICOM prefix and the data type field
Embodiments of the present invention are described below in connection with the DICOM file format. DICOM files refer to medical files stored in accordance with the DICOM standard. The fifth part of the DICOM standard introduces its Data structure, defines a Data Set (Data Set) to hold Information Object Definitions (IODs), and is made up of a number of Data elements (Data elements).
FIG. 2 is a schematic diagram of a DICOM file format. As shown in FIG. 2, the DICOM file 20 includes a DICOM header 31 and a DICOM data collection 32.
The DICOM file header 31 contains information about the identification data set and each DICOM file includes a header. The DICOM header 31 contains information that identifies the data set. Specifically, the DICOM header 31 includes: (1) a file header 21 consisting of 128 bytes; (2) A DICOM prefix 22 for determining whether the file is a DICOM file based on whether a string of 4 bytes in length is equal to "DICOM"; (3), a file information element 23.
The DICOM data set 32 is the main component of the DICOM file 31 and comprises a plurality of data elements 24. Each data element 24 comprises: (1), DICOM TAG (TAG) 41: storing an identification of the item of information; (2) Value representation (value representation, VR) field 42: storing a data type describing the item of information; (3), value length field 43: storing a data length describing the item of information; (4), value (value) field 44: a data value describing the item of information is stored.
The DICOM standard defines 27 basic data types, i.e., 27 VR, in PS 3.5.
Specifically, the value representation field 42 may include: (1) Code String (CS); (2), short String (SH); (3), long Strings (LOs); (4), short Text (ST); (5), long Text (LT); (6), unlimited Text (UT); (6), application entity (Application Entity, AE); (8), patient Name (PN); (9), unique identifier (Unique Identifier, UI); (10), date (Data, DA); (11), time (Time, TM); (12), date Time (DT); (13), age String (AS); (14) Integer Strings (IS); (15), small Digit Strings (DS); (16), signed Short (SS); (17), unsigned Short (US); (18), signed Long (SL); (19), unsigned Long length (UL); (20), attribute Tags (AT); (21), single precision Floating point (FL); (22) A double-precision binary floating point number (Floating Point Double, FD); (23) Other byte strings (Other Byte String, OB); (24) Other word strings (Other Word String, OW); (25) Other floating point strings (Other Float String, OF); (26), a Sequence of entries (SQ); (27), unknown (UN).
In one embodiment, it may be determined whether a DICOM file feature is detected based on the DICOM prefix 22.
Specifically, when a DICOM prefix equivalent to a predetermined character is detected from the duplicate data packet, the detection of the DICOM file feature may be deemed.
For example, a DICOM file feature may be identified as detected when a DICOM prefix (i.e., a 4-byte string "DICM") is detected after a length of the file header 31 (i.e., 128 bytes) from a start bit of a payload field of a duplicate packet. At this point, the full DICOM file may be fetched starting from the start bit of the payload field of the duplicate packet. In this embodiment, there is the advantage of fast detection simply by determining whether a DICOM prefix is detected, i.e., whether a DICOM file feature is detected.
In one embodiment, it may also be determined whether a DICOM file feature is detected based on the DICOM prefix 22 and the value representation field 42 together. Specifically, the DICOM file feature may be determined to be detected when a DICOM prefix equivalent to a first predetermined character and a data type field equivalent to a second predetermined character are detected from the duplicate data packet.
For example, a DICOM file feature may be considered detected when a DICOM prefix (i.e., a 4-byte string "DICM") is detected after the length of the file header 31 (i.e., 128 bytes) from the start of the payload field of the duplicate packet, and any of the 27 basic data types described above is detected from the VR field 42. At this point, the full DICOM file may be fetched starting from the start bit of the payload field of the duplicate packet. In this embodiment, by comprehensive detection of the DICOM prefix and data type fields, it may be accurately determined whether DICOM file characteristics are detected.
While the above exemplary embodiment has been described in terms of detecting characteristics of a DICOM file, those skilled in the art will recognize that this description is exemplary only and is not intended to limit the scope of embodiments of the present invention.
In summary, the embodiment of the invention can extract the DICOM file based on the copy data packet of the data packet sent by the medical imaging device, can obtain the DICOM file without relying on PACS, has wide application range, is convenient to implement, and can save cost. Moreover, the copied data packet can be synchronous with the data packet sent by the medical imaging equipment, so that the DICOM file can be obtained in real time according to the embodiment of the invention.
