Four-dimensional contrast image generation method, device, equipment and storage medium

Abstract

The invention discloses a four-dimensional contrast image generation method. The method can comprise the following steps of: obtaining contrast data of a current frame of a target part; determining whether the swing of the ultrasonic probe reaches a preset correction condition or not according to the positioning information of the ultrasonic probe; if yes, correcting the contrast data, and generating a four-dimensional time rendering image based on the corrected contrast data; and if not, generating a four-dimensional time rendering image based on the contrast data. By applying the technical scheme provided by the embodiment of the invention, the problem of color disorder of a rendering result of time imaging caused by image deviation caused by swing of the ultrasonic probe can be effectively avoided, meanwhile, adjustment of contrast image deviation does not need to be achieved through time-consuming and low-efficiency three-dimensional feature matching operation, and the four-dimensional contrast image generation efficiency is improved. The invention further discloses a four-dimensional contrast image generation device and equipment and a storage medium which have corresponding technical effects.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, device, equipment and storage medium for generating a four-dimensional contrast image. Background technique [0002] With the advancement of medical technology, imaging technology has gradually developed. Contrast radiography, in diagnostic radiology, takes radiographs of parts of the body to be diagnosed by ingesting substances containing elements with high atomic numbers for medical diagnosis. For structures or organs that lack natural contrast, a substance with a density higher or lower than that of the structure or organ, that is, a contrast agent, can be introduced into the organ or its surrounding space to produce contrast imaging. [0003] In order to conveniently and intuitively observe the method and process of the contrast agent flow, a multi-segment color pseudo-color can be used in the imaging process to correspond the flow of the contras...

Problems solved by technology

However, if the ultrasonic probe swings too much during the image acquisition process, it will be difficult to effectively match the 3D image and the rendering color will be disordered.
