Abstract

The invention discloses a medical DICOM (Digital Imaging and Communications in Medicine) image display method. The method comprises the following steps that: obtaining one study of a patient, wherein the study comprises a plurality of DICOM image files; analyzing each DICOM image file in the study on a server side, obtaining metadata and an image in each DICOM image file, and storing all piece of obtained metadata in the study to a metadata file, and storing each obtained image as one picture; and through an HTTP (Hyper Text Transport Protocol), requesting the metadata file and the pictures of the server side by a browser client side, displaying the frame diagram of the study, and using the HTML (Hypertext Markup Language) Appcache of the browser client side to cache the picture which is not displayed for the moment, and if the DICOM image display request of the study is carried out, responding by the HTML Appcache of the browser client side. By use of the method, the image loading speed, the image display speed and the image operation speed of the client side can be quickened, and the network traffic of a user is saved.

Description

technical field [0001] The invention belongs to the field of image display, in particular to a medical DICOM (Digital Imaging and Communications in Medicine, DICOM for short) image display method. Background technique [0002] DICOM image files are an international standard to be followed by X-ray, CT, MRI, ultrasound and other medical imaging equipment. When the images produced by medical imaging equipment are saved in the form of files, they must also meet the format specified by the DICOM standard. DICOM files are generally viewed by professional software, and the commonly used special software is a dedicated desktop application or App. For example, HTML5 DICOM Viewer is a web software that uses the Canvas element (Element) in the HTML5 standard to display DICOM images. However, the traditional implementation of HTML5 DICOM Viewer generally provides only the download of the original DICOM file on the server side, directly downloads the DICOM file in the browser page, an...
