Embodiment Construction

[0042] The current Web+DICOM is to load the entire medical image to be displayed by the browser, which takes a long time to load. However, the present invention only loads the part of the medical image in the display area by performing block processing on the DICOM medical image, and does not load the non-display area part, thereby reducing the amount of data loaded by the browser and greatly improving the loading speed of the medical image .

[0043] Such as figure 1 As shown in FIG. 1 , it is a functional block diagram of processing medical image blocks and quickly displaying them on the Web in the present invention. Among them, the arrow lines indicate the processing flow. According to the position of the display area of ​​the browser on the DICOM medical image (hereinafter referred to as "medical image"), the display area is divided into N block areas according to the preset block length, and each block area generates a corresponding URL, and create an image object (or ...

Abstract

The invention discloses a method for displaying medical images on a browser rapidly. The method includes the steps of (1) dividing a display area into multiple area blocks according to the location of the display area of the browser on a DICOM (digital imaging and communications in medicine) medical image, (2) acquiring WADO (web access to DICOM persistent objects) request parameter of each image block corresponding to each area block according to a WADO protocol and calculating a URL(uniform resource locator) of each area block, (3) dividing the DICOM medical image into multiple image blocks, (4) creating an image object for each area block, (5) by the browser, setting a URL for the image object of each area block and sending the URL for the image object to a service terminal, and (6) according to the WADO request parameter of each image block, by the service terminal, loading the image block corresponding to each area block to the browser to display the DICOM medical image. As the DICOM medical image is subjected to a blocking process and only the part of the display area but the non-display area is loaded, data quantity for image loading of the browser is reduced and loading speed of the medical image is increased greatly.

Description

technical field [0001] The invention relates to a medical image display technology, in particular to a method for rapidly displaying medical images on a browser using image block technology. Background technique [0002] The resolution of medical images is high, and the pixel grayscale value is usually not lower than 12-bit (Bit) 4096. However, due to the limited dynamic range and the limitation of the operating system, ordinary displays can only provide 8Bit256 grayscale. Relatively stable value, only interested in pixel values ​​in a specific range when performing image segmentation processing, therefore, the processing system must be able to display specific pixel values ​​according to the needs of researchers, and shield pixel values ​​in other ranges. [0003] Generally speaking, this function is realized by adjusting the window width and window level. Adjusting the window width and window level is a display technology used in medical image processing to observe tissue ...
