detailed description

In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention, and are not used to limit the protection scope of the present invention.

For the sake of brevity and intuition in description, the solution of the present invention is explained below by describing several representative embodiments. Numerous details in the embodiments are provided only to aid in understanding the aspects of the invention. However, it is obvious that the technical solutions of the present invention may not be limited to these details during implementation. In order to avoid unnecessarily obscuring aspects of the present invention, some embodiments are not described in detail, but merely framed. Hereinafter, "including" means "including but not limited to", and "according to..." means "at least in accordance with..., but not limited to, only in accordance with...". Due to the language habit of Chinese, when the number of a component is not specified below, it means that the component can be one or more, or can be understood as at least one.

The applicant found that in the prior art, a PACS or a medical imaging device directly provides a complete DICOM file to a client. However, DICOM files are usually large, and this blind file transfer method has the disadvantage of low transfer efficiency. In the research aimed at solving this technical problem, the applicant also found that the device for sending DICOM files can accurately determine to send image files, DICOM files or compressed files to the client based on different instructions received from the client, thereby improving the transmission efficiency. efficient.

FIG. 1 is a flowchart of a method for sending a DICOM file according to an embodiment of the present invention. The method is suitable for execution by the device sending the DICOM file. For example, the device for sending DICOM files can be specifically implemented as a server deployed in the PACS, or a server separate from the PACS.

As shown in Figure 1, the method includes:

Step 101: Generate an image file based on the pixel data contained in the DICOM file.

Here, the device sending the DICOM file can access the PACS to obtain the DICOM file, and save the DICOM file in its own storage medium. Optionally, the device for sending the DICOM file may also directly obtain the DICOM file from the medical imaging device, and save the DICOM file in its own storage medium. Medical imaging equipment refers to various instruments that use various media as information carriers to reproduce the internal structure of the human body as images. The image information and the actual structure of the human body have a corresponding relationship in space and time distribution. Generally, the medical imaging equipment may include X-ray equipment, CT equipment, magnetic resonance equipment, ultrasound equipment and so on. The medical imaging device can generate DICOM files, and encapsulate the DICOM files into data packets based on a predetermined transmission protocol (eg, TCP/IP protocol or CAN protocol, etc.) or router, etc.) to send the packet out, such as to a PACS or a device that sends a DICOM file.

In one embodiment, when the apparatus for sending the DICOM file is embodied as a server deployed in the PACS, the server can obtain the DICOM file from the PACS.

In one embodiment, when the apparatus for sending the DICOM file is embodied as a server separate from the PACS, the server may obtain the DICOM file from the PACS based on the communication connection with the PACS.

In one embodiment, when the apparatus for sending the DICOM file is embodied as a server separate from the PACS, the server can obtain the DICOM file from the medical imaging device based on the communication connection with the medical imaging device.

The above exemplarily describes a typical implementation of acquiring a DICOM file, and those skilled in the art can realize that this description is only exemplary, and is not intended to limit the protection scope of the implementation of the present invention.

In the device that transmits the DICOM file, an image file is generated based on pixel data contained in the DICOM file, and the image file is further saved in the device that transmits the DICOM file.

In one embodiment, the sampling rate of the pixel data contained in the DICOM file is reduced based on a predetermined window width and window level parameter; based on the pixel data after the reduced sampling rate, an image file having an image format is generated, wherein the image format includes the following At least one of: Bitmap file (BMP) format; Image Interchange Format (GIF); Tagged Image File Format (TIF); Joint Photographic Experts Group (JPEG) format; IOS15444 file format; Interchange File Format (IFF); Exchange Image File Format (EXIF); Portable Network Graphics (PNG) format, etc.

It can be seen that by reducing the sampling rate of pixel data in the DICOM file, the storage amount of pixel data (binary) can be reduced. Moreover, the storage amount of the image file having the image format generated based on the pixel data is further reduced, thereby facilitating the storage and transmission of the image file.

Step 102: Generate a compressed file of the DICOM file.

Here, a compressed file of the DICOM file is generated in the device that transmits the DICOM file, and the DICOM file and the compressed file are saved.

Wherein, the compressed file of the DICOM file can be generated based on various predetermined file compression methods. For example, a lossless compression algorithm or a lossy compression algorithm can be used to generate a compressed file of the DICOM file. Among them, lossless compression algorithms include: differential coding, RLE, Huffman coding, LZW coding, arithmetic coding, and so on. Lossy compression algorithms include: predictive coding, pitch coding, fractal compression, wavelet compression, JPEG/MPEG, and so on.

The above exemplarily describes a typical implementation for generating a compressed file of a DICOM file, and those skilled in the art can realize that this description is only exemplary, and is not intended to limit the protection scope of the embodiments of the present invention.

There is no specific requirement for the execution sequence of step 101 and step 102. That is: (1), step 101 may be performed first, and then step 102; (2), step 102 may be performed first, and then step 101; (3), step 101 and step 102 may be performed simultaneously.

Step 103: When receiving an image sending instruction, send an image file; when receiving a file sending instruction, send a DICOM file or a compressed file.

Here, when the device for sending the DICOM file receives an image sending instruction from the client, it sends the image file to the client; when the device for sending the DICOM file receives the file sending instruction from the client, it sends the DICOM file or compression to the client document. When the size of the DICOM file exceeds a predetermined threshold, the compressed file is sent; when the size of the DICOM file does not exceed the threshold, the DICOM file is sent. Preferably, the threshold value may be 10 megabytes (MB).

When the client wants to browse the image file, the client sends an image sending instruction to the device that sends the DICOM file; when the client wants to browse the DICOM file, the client sends a file sending instruction to the device that sends the DICOM file. The device for sending DICOM files can accurately determine to send image files, DICOM files or compressed files based on different instructions received from the client, thereby improving transmission efficiency.

In one embodiment, the method further includes: sending paging information of the image file; when receiving a preloading instruction including the current page number, sending the image file in the page number related to the current page number. Preferably, the paging information of the image file includes the total number of image files and the number of paging.

Preferably, the image file of the page number relative to the current page number usually includes:

(1), the image file in the current page number;

(2), the image file of the page number medium number within the predetermined range before the current page number;

(3) An image file in a page number within a predetermined range after the current page number.

It can be seen that, in the embodiment of the present invention, images can be displayed efficiently by means of preloading.

For example: the server sends the paging information of the image file to the client, the paging information specifically includes the total number of image files (for example, 100) and the number of pages (for example, 5 pages, each page has 20 images). Based on the paging information, the client generates a display page containing 5 pages, where each page can display 20 images. When the client detects that the user drags to the bottom of the third page and stays there for a predetermined time (for example, two seconds), the client sends a preload instruction containing the current page number (ie, 3) to the server, and the server sends the second The image file for the page, the image file for the 3rd page, and the image file for the 4th page. The client displays the image file of page 3, and preloads the image file of page 2 and the image file of page 4 in the background. Therefore, when the user drags the page forward or backward after browsing the third page, the image of the second page and the image of the fourth page can be quickly displayed, so that the images can be displayed efficiently.

Wherein, between the client and the device for sending the DICOM file, the transmission of instructions and files can be realized through a wired interface or a wireless interface. The wired interface includes at least one of the following: a universal serial bus interface, a controller area network interface, a serial port, etc.; the wireless interface includes at least one of the following: an infrared interface, a near field communication interface, a Bluetooth interface, a ZigBee interface, and a wireless broadband interface , third-generation mobile communication interface, fourth-generation mobile communication interface, fifth-generation mobile communication interface, and so on.

Figure 2 is a schematic diagram of the DICOM file format. As shown in FIG. 2 , the DICOM file 20 includes a DICOM file header 31 and a DICOM data set 32 .

The DICOM file header 31 contains relevant information identifying the data set, and each DICOM file includes a file header. The DICOM file header 31 contains relevant information identifying the data set. Specifically, the DICOM file header 31 includes: (1), a file introduction 21, which is composed of 128 bytes; (2), a DICOM prefix 22, which can be judged according to whether a character string with a length of 4 bytes is equal to "DICM" Whether the file is a DICOM file; (3), the file information element 23.

The DICOM data set 32 is the main component of the DICOM file 31 and contains a plurality of data elements 24 . Each data element 24 includes: (1) DICOM tag (TAG) 41: the identifier for storing the item of information; (2), value representation (VR) field 42: storing the data type describing the item of information; ( 3), the value length field 43: storing the data length describing the item of information; (4), the value (value) field 44: storing the data value describing the item of information.

The DICOM standard defines 27 basic data types in PS3.5, that is, 27 VRs are defined. Specifically, the value representation field 42 may include: (1), code string (Code String, CS); (2), short string (Short String, SH); (3), long string (Long String, LO) ); (4), Short Text (ST); (5), Long Text (LT); (6), Unlimited Text (Unlimited Text, UT); (6), Application Entity (Application Entity, AE); (8), Patient Name (Person Name, PN); (9), Unique Identifier (UI); (10), Date (Data, DA); (11), Time (Time) , TM); (12), Date Time (Date Time, DT); (13), Age String (Age String, AS); (14), Integer String (Integer String, IS); (15), Decimal String (Decimal String, DS); (16), Signed Short (SS); (17), Unsigned Short (Unsigned Short, US); (18), Signed Long (Signed) Long, SL); (19), Unsigned Long (UL); (20), Attribute Tag (AT); (21), Floating Single (FL); (22) ), double-precision binary floating point numbers (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), item sequence (Sequence Items, SQ); (27), unknown (Unknown, UN).
