Detailed Description
In order to make the technical scheme and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
The applicant found that: in the prior art, PACS or medical imaging devices provide a complete DICOM file directly to the client. However, DICOM files are usually large, and this blind file transfer method has a disadvantage of low transfer efficiency. In the studies intended to solve the technical problem, the applicant has also found that: the DICOM file transmitting device can accurately judge whether to transmit the image file, the DICOM file or the compressed file thereof to the client based on different instructions received from the client, thereby improving the transmission efficiency.
Fig. 1 is a flowchart of a method of transmitting a DICOM file according to an embodiment of the present invention. The method is adapted to be performed by a device for transmitting DICOM files. For example, the apparatus for sending DICOM files may be embodied as a server deployed in the PACS, or a server separate from the PACS.
As shown in fig. 1, the method includes:
step 101: an image file is generated based on the pixel data contained in the DICOM file.
Here, a device transmitting a DICOM file may access the PACS to acquire the DICOM file and save the DICOM file in its own storage medium. Alternatively, the apparatus for transmitting the DICOM file may directly acquire the DICOM file from the medical image device and store the DICOM file in its own storage medium. The medical imaging equipment is various instruments which use various different media as information carriers to reproduce the internal structure of a human body into images, and the image information of the medical imaging equipment has a corresponding relation in space and time distribution with the actual structure of the human body. Generally, the medical imaging apparatus may include an X-ray apparatus, a CT apparatus, a magnetic resonance apparatus, an ultrasound apparatus, and the like. The medical imaging device may generate a DICOM file, 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 via a data switching device (e.g., a switch or router, etc.) connected to the medical imaging device, such as to a PACS or a device sending the DICOM file.
In one embodiment, when the device sending the DICOM file is embodied as a server deployed in a PACS, the server may retrieve the DICOM file from the PACS.
In one embodiment, when the device sending the DICOM file is embodied as a server separate from the PACS, the server may retrieve the DICOM file from the PACS based on a communication connection with the PACS.
In one embodiment, when the apparatus for transmitting the DICOM file is embodied as a server separate from the PACS, the server may retrieve the DICOM file from the medical imaging device based on a communication connection with the medical imaging device.
While the above exemplary description describes an exemplary embodiment for obtaining a DICOM file, those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of embodiments of the present invention.
In a DICOM file transmitting apparatus, an image file is generated based on pixel data included in the DICOM file, and the image file is further stored in the DICOM file transmitting apparatus.
In one embodiment, the sampling rate of pixel data contained in a DICOM file is reduced based on a predetermined window width level parameter; generating an image file having an image format based on the pixel data after the sampling rate reduction, wherein the image format includes at least one of: bitmap file (BMP) format; image interchange format (GIF); tag image file format (TIF); joint Photographic Experts Group (JPEG) format; IOS15444 file format; interchange File Format (IFF); exchangeable image file format (EXIF); portable Network Graphics (PNG) format, and so on.
It can be seen that by reducing the sampling rate of the pixel data in the DICOM file, the amount of storage of the pixel data (binary) can be reduced. Moreover, the storage capacity of an image file having an image format generated based on pixel data is further reduced, thereby facilitating storage and transmission of the image file.
Step 102: and generating a compressed file of the DICOM file.
Here, the apparatus for transmitting the DICOM file generates a compressed DICOM file, and stores the DICOM file and the compressed DICOM file.
The compressed DICOM file may be generated based on various predetermined file compression methods. For example, a lossless compression algorithm or a lossy compression algorithm may be used to generate a compressed DICOM file. Wherein, the lossless compression algorithm comprises: differential encoding, RLE, Huffman encoding, LZW encoding, arithmetic encoding, and the like. The lossy compression algorithm includes: predictive coding, perceptual coding, fractal compression, wavelet compression, JPEG/MPEG, and the like.
While the above exemplary description describes exemplary embodiments of generating a compressed file of a DICOM file, those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of embodiments of the present invention.
The execution sequence of step 101 and step 102 is not particularly required. Namely: (1) step 101 may be performed first, and then step 102 may be performed; (2) step 102 may be performed first, and then step 101 may be performed; (3) step 101 and step 102 may be performed simultaneously.
Step 103: when an image sending instruction is received, sending an image file; when a file sending instruction is received, the DICOM file or the compressed file is sent.
Here, when the apparatus transmitting the DICOM file receives an image transmission instruction from the client, the apparatus transmits the image file to the client; when the device for sending the DICOM file receives a file sending instruction from the client, the DICOM file or the compressed file is sent to the client. When the size of the DICOM file exceeds a preset threshold value, sending the compressed file; and when the size of the DICOM file does not exceed a threshold value, transmitting the DICOM file. Preferably, the threshold value may be 10 Megabytes (MB).
When the client desires to browse the image file, the client sends an image sending instruction to a device sending the DICOM file; when the client desires to view the DICOM file, the client sends a file transmission instruction to the device that transmitted the DICOM file. The apparatus for transmitting the DICOM file can accurately judge whether to transmit the image file, the DICOM file or the compressed file thereof based on different instructions received from the client, thereby improving transmission efficiency.
In one embodiment, the method further comprises: transmitting paging information of the image file; and when a preloading instruction containing the current page number is received, sending the image file in the page number related to the current page number. Preferably, the paging information of the image files includes the total number of the image files and the number of pages.
Preferably, the image file of the page number associated with the current page number generally includes:
(1) image files in the current page number;
(2) the image file of the page number in the preset range before the current page number;
(3) and image files in the page numbers within a predetermined range after the current page number.
Therefore, the image can be efficiently displayed in a preloading mode.
Examples are: the server transmits to the client page information of the image files, which specifically includes the total number of image files (e.g., 100 pages) and the page number (e.g., 5 pages, 20 images per page). The client generates a presentation page containing 5 pages, each of which can present 20 images, based on the paging information. When the client detects that the user drags to the bottom of the 3 rd page and stays for a preset time (such as two seconds), the client sends a preloading instruction containing the current page number (namely 3) to the server, and the server sends the image file of the 2 nd page, the image file of the 3 rd page and the image file of the 4 th page to the client. The client presents 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 3 rd page, the image of the 2 nd page and the image of the 4 th page can be displayed quickly, thereby displaying the images efficiently.
The transmission of the instructions and the files can be realized between the client and the device for sending the DICOM files through a wired interface or a wireless interface. The wired interface includes at least one of: a universal serial bus interface, a controller area network interface, a serial port, etc.; the wireless interface includes at least one of: infrared interface, near field communication interface, bluetooth interface, zigbee interface, wireless broadband interface, third generation mobile communication interface, fourth generation mobile communication interface, fifth generation mobile communication interface, and so on.
