Embodiment Construction

[0030] The present invention combines the WADO (Web Access to DICOM Persistent Object) protocol in the DICOM3.0 (Digital Imaging and Communications in Medicine) standard and the data information of the DIOCM file, adopts an efficient and accurate server-side positioning line algorithm and a client-side display algorithm, based on HTML5 The canvas attribute of (Hypertext MarkupLanguage) finally realizes the display of CT / MR image sequence positioning lines on the browser. Therefore, the present invention can complete the positioning line drawing of medical images on the browser without installing any plug-ins, and can enable doctors to use any mobile device to log in to the browser anytime and anywhere, access the medical image server through the website and complete the medical image on the browser. The positioning line drawing can accurately judge the position of the patient's lesion with the help of the positioning line, thereby improving the efficiency and accuracy of diagno...

Abstract

The invention discloses a method for drawing a medical image positioning line on a browser, which includes the steps: the browser constructs a request URL based on the WADO protocol for the unique identification UID of the positioning image and the slice image in the medical image, and sends it to the Web medical image server Request the URL; the Web medical imaging server reads the required DICOM file information by parsing the request URL, calculates the two-dimensional coordinate value required for drawing the positioning line through the positioning image, and then returns the two-dimensional coordinate value to the browser; Dimensional coordinate value, use the canvas attribute in HTML5 to draw the positioning line on the sliced ​​image of the medical image. The invention completes the drawing of the positioning line of the medical image on the browser, and accurately judges the position of the patient's lesion with the help of the positioning line, thereby improving the efficiency and accuracy of diagnosis, and providing an important auxiliary tool for accurate diagnosis of remote consultation.

Description

technical field [0001] The present invention relates to medical image processing technology, in particular to a method for drawing medical image positioning lines on a browser Background technique [0002] For example, there are a large number of slices in CT and MR sequences. Doctors need to look at multiple groups of different viewpoints to diagnose the lesion. By analyzing a sequence of two-dimensional slice images of human tissues and organs, doctors can obtain the size and shape of the lesion, which is convenient for diagnosis. . However, the positioning of CT slice images and the mutual positioning of different MR slices are difficult problems. For a certain image, doctors do not know the exact position of the slice image on the tissue and organ. [0003] The existing technology is based on the PC client to draw the positioning line on the medical image. Due to the poor mobile performance of the PC terminal, it cannot meet the needs of doctors to accurately locate the...
