Detailed Description
The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the application and together with the description, serve to explain the principles of the application and not to limit the scope of the application.
In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, the present application provides a DICOM file transfer method, including the steps of:
s101, obtaining an initial pixel tag value in an initial DICOM file to obtain an initial pixel value file;
s102, dividing the initial pixel value file into a plurality of pixel value sub-files;
s103, generating a plurality of corresponding DICOM subfiles according to the plurality of pixel value subfiles and the initial DICOM file;
and S104, sending the plurality of DICOM subfiles through a preset transmission protocol.
In this embodiment, the initial DICOM file is a DICOM file to which medical images are transmitted. The data size of the pixel information of the transmitted medical image is relatively large, and generally occupies more than 97% of the size of the initial DICOM file. Generally, after the DICOM file is parsed by a professional tool, a table containing a plurality of tag information is presented, each row of information of the table includes ID, description, type, length and tag value (tag value) of the tag, for example, ID of a certain row of tag is 00100010, description is patient's Name, type is PN, length is 10, tag value is wu XX; other tag information such as height, weight and the like of the patient are also recorded in the DICOM file table; in addition, the DICOM file table has tag information with ID 7FE00010, the tag value is the pixel content of the transmitted medical image, and the pixel content accounts for 97% or more of the size of the DICOM file, so the present embodiment divides the tag value of the DICOM file into a pixel tag value and a non-pixel tag value. In this embodiment, the specific content of the initial pixel tag value is in the form of an attachment, i.e., an initial pixel value file, existing in the initial DICOM file. The initial pixel value file refers to a pixel information file of the transmitted medical image. In this embodiment, the preset transmission protocol is a DICOM communication protocol, and under the DICOM communication protocol, a connection pool is established, and each DICOM subfile is transmitted to the target receiving end in a concurrent manner.
In the embodiment, the initial pixel value file is obtained by reading the initial pixel tag value of the initial DICOM file, so that the initial pixel value file is divided into a plurality of pixel value subfiles, and the initial DICOM file is conveniently transmitted in blocks; generating a plurality of corresponding DICOM subfiles according to the plurality of pixel value subfiles and the initial DICOM file, and ensuring that the basic label information of each DICOM subfile is complete so as to meet the transmission protocol; and then, sending the plurality of DICOM subfiles through a preset transmission protocol, thereby smoothly completing the block transmission of the DICOM subfiles and being beneficial to a receiving end to normally display the transmitted medical images. It should be noted that, compared with the original DICOM file, each DICOM subfile has completely consistent non-pixel tag values except for the integrity of the pixel tag values, which can support DICOM protocol transmission and storage.
In one embodiment, in step S102, the initial pixel value file is divided into several pixel value sub-files by using an equal division or non-equal division method. In this embodiment, the content of the initial pixel value file may be divided equally, for example, into 10, 15, or 20 equal portions in sequence. In other embodiments, the segmentation may also be performed in a non-uniform manner. In addition, it should be noted that, in the dividing process, a corresponding dividing sequence number may be recorded for each pixel value subfile.
In an embodiment, referring to fig. 2, step S103, generating corresponding pieces of DICOM subfiles according to the pieces of pixel value subfiles and the initial DICOM file, includes:
s201, taking each pixel value in the plurality of pixel value subfiles as a first sub-pixel label value to obtain a plurality of first sub-pixel label values;
s202, reading all non-pixel label values in the initial DICOM file, combining the first sub-pixel label values with the non-pixel label values according to a transmission protocol, and generating a plurality of corresponding DICOM sub-files.
In the present embodiment, the specific content of each pixel value subfile is the divided pixel value information; the first sub-pixel label value is a new sub-pixel label value, so that each pixel value in the divided sub-files of pixel values can be used as the first sub-pixel label value. Reading all non-pixel tag values in the initial DICOM file, combining each first sub-pixel tag value with all non-pixel tag values according to a transmission protocol to generate each corresponding DICOM sub-file, and enabling each DICOM sub-file to be a file with relatively complete tag information, so that the DICOM communication protocol is met.
In another embodiment, referring to fig. 3, the step S103 of generating corresponding pieces of DICOM subfiles according to the pieces of pixel value subfiles and the initial DICOM file includes:
s301, taking each pixel value in the plurality of pixel value subfiles as a second sub-pixel label value to obtain a plurality of second sub-pixel label values;
s302, the second sub-pixel label values are respectively and correspondingly replaced with the initial pixel label value in the initial DICOM file, and each corresponding DICOM sub-file is obtained.
In this embodiment, each pixel value subfile is separately added to the initial DICOM file in an attached form, that is, each second sub-pixel tag value replaces the initial pixel tag value in the initial DICOM file, so that each different DICOM subfile can be obtained, each DICOM subfile includes the initial non-pixel tag value and the corresponding second sub-pixel tag value, and has relatively complete tag information, thereby satisfying the transmission protocol.
It is understood that the first sub-pixel label value and the second sub-pixel label value are actually the same sub-pixel label, and the present application distinguishes between the first sub-pixel label value and the second sub-pixel label value for distinguishing the embodiments. In addition, it should be noted that, compared with the prior art that a DICOM file after simple physical partitioning cannot support a DICOM transmission protocol and cannot be normally used to acquire tag information, each integrated DICOM subfile after partitioning has relatively complete tag information and supports the DICOM transmission protocol, a receiving end system can normally acquire each tag information of each DICOM subfile, thereby facilitating smooth completion of DICOM file transmission, storage and display of medical images.
Referring to fig. 4, the present application provides a DICOM file storage method, based on the DICOM file transmission method, the storage method includes the following steps:
s401, receiving a plurality of DICOM subfiles, and reading first sub-pixel tag values/second sub-pixel tag values of the DICOM subfiles to obtain corresponding pixel value subfiles to be spliced; each pixel value subfile to be spliced carries a corresponding original segmentation serial number;
s402, splicing and combining all the sub-files of the pixel values to be spliced to obtain a spliced initial pixel value file; merging the sequence numbers according to the corresponding original segmentation sequence in the splicing process;
and S403, taking the spliced pixel value file as a target pixel label value, and obtaining an initial DICOM file based on any one of the DICOM subfiles.
In a specific embodiment, when the receiving is finished, for example, 10 DICOM subfiles exist, the first sub-pixel tag value/the second sub-pixel tag value of each DICOM subfile is read to obtain corresponding 10 to-be-spliced pixel value subfiles; then all the sub-files of the pixel values to be spliced are merged according to the corresponding original segmentation sequence numbers to obtain a spliced initial pixel value file; and taking the spliced initial pixel value file as a target pixel label value, and obtaining an initial DICOM file based on any DICOM subfile in each DICOM file. In other embodiments, the number of DICOM subfiles received is determined based on the number of actual segmentations.
In an embodiment, referring to fig. 5, in step S403, the initial pixel value file to be spliced is used as a target pixel tag value, and the initial DICOM file is obtained based on any one of the DICOM subfiles, which includes:
s501, reading all non-pixel label values in any DICOM subfile;
s502, combining the target pixel tag value and all non-pixel tag values in any DICOM subfile according to a preset transmission protocol to generate an initial DICOM file.
It should be noted that the target pixel label value refers to a complete initial pixel value file obtained after stitching. After receiving all DICOM subfiles, reading all non-pixel tag values of any DICOM subfile; and then combining the target pixel tag value and all non-pixel tag values in any DICOM subfile according to a preset transmission protocol to generate a complete initial DICOM file, so that the transmitted medical image can be completely displayed.
In another embodiment, the step S403 takes the spliced initial pixel value file as a target pixel tag value, and obtains an initial DICOM file based on any DICOM subfile in each DICOM file, including: and replacing the first sub-pixel label value/the second sub-pixel label value in any DICOM sub-file with the target pixel label value to generate an initial DICOM file.
Specifically, a complete initial DICOM file can be quickly obtained by replacing the pixel value subfile of any DICOM subfile with the spliced initial pixel value file.
Different from the prior art, in the embodiment, the initial pixel value file is obtained by reading the initial pixel tag value of the initial DICOM file, so that the initial pixel value file is divided into a plurality of pixel value subfiles, and the subsequent transmission of the initial DICOM file in blocks is facilitated; generating a plurality of corresponding DICOM subfiles according to the plurality of pixel value subfiles and the initial DICOM file, and ensuring that the basic label information of each DICOM subfile is complete so as to meet the transmission protocol; and then, sending the plurality of DICOM subfiles through a preset transmission protocol, thereby smoothly completing the block transmission of the DICOM subfiles. In addition, the target receiving end receives each DICOM subfile, reads a first sub-pixel tag value/a second sub-pixel tag value of each DICOM subfile, and obtains a corresponding to-be-spliced pixel value subfile; then, splicing and combining all the sub-files of the pixel values to be spliced to obtain a spliced initial pixel value file; and then, the spliced initial pixel value file is used as a target pixel label value, and based on any one DICOM subfile of the plurality of DICOM subfiles, the complete initial DICOM file can be quickly obtained, so that the initial DICOM file is smoothly stored, and the transmitted medical image can be normally displayed.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
