Method and system for rendering medical image

Abstract

The invention provides a method and system for rendering a medical image. The method comprises the following steps that a medical image loading request is initiated from a client to a server; medical image data is loaded on the server, first-stage rendering operation is carried out to generate a first rendering result; the first rendering result is sent to the client from the server; the first rendering result is shown on the client; the medical image data is preprocessed on the server; the processed medical image data is sent to the client on the server; the client receives the preprocessed medical image data, and the medical image data is prepared to be used for rendering; the client makes a response to continuous operation of a user, and the preprocessed medical image data is used for second-stage rendering operation, and a second rendering result is generated, wherein the precision of the second rendering result is lower than that of the first rendering result; the second rendering result is shown on the client during continuous operation.

Description

technical field [0001] The present invention mainly relates to medical image data processing, in particular to a medical image rendering method and system. Background technique [0002] With the development of medical imaging technology and computer technology, imaging technologies and equipment such as X-ray imaging, computed tomography (CT), magnetic resonance imaging (MR), ultrasound imaging (US) and positron emission tomography (PET) are widely used in medical institutions. It plays a very important role in clinical and R&D work. The medical image data generated by these medical imaging devices are usually stored in a storage system such as a picture archiving and communication system (PACS). When users need it, they can request query and access to the server of the storage system. [0003] Because medical images, especially 3D medical images, have a large amount of data, their rendering requires high-performance graphics cards and takes up a lot of video memory, so it...

AI Technical Summary

Problems solved by technology

The extreme dependence on the server and network side will cause unstable rendering results

For example, if the rendering result is not returned in time due to server load, network, etc., the user will feel obvious lag and affect the viewing experience

On the other hand, when the amount of data in the existing storage system reaches a certain scale, the access efficiency will be greatly reduced, and the way of relying too much on the server will also increase the burden on the server
