Calcification artifact elimination method, device and computer storage medium

Abstract

The invention discloses a method, equipment and computer storage medium for eliminating calcification artifacts. The method includes: acquiring and processing original blood vessel image data to obtain original calcification image data; performing fitting processing on the original calcification image data to obtain A gray-scale change surface; extracting the original calcification image data according to the gray-scale change surface to obtain an image of a calcification central region; adjusting according to the image of the calcification central region to obtain an artifact-corrected calcification image. In the embodiment of the present invention, after the initial calcification area is extracted from the original image, grayscale fitting is performed on the image data of the original calcification area to obtain a grayscale change surface, and the grayscale change surface is used to eliminate the influence of artifacts again, so as to obtain a more accurate The method for correcting the calcified image with artifacts can better eliminate the effect of calcification artifacts, and is beneficial to obtain more accurate calcification calculation results.

Description

technical field [0001] The present invention relates to the technical field of blood vessel images, in particular to a method, device and computer storage medium for eliminating calcification artifacts. Background technique [0002] In the field of modern medical technology, the automatic coronary stenosis result calculation technology can quickly produce the results of the patient's condition, which is very helpful for clinicians. When calculating the automatic stenosis, an important issue is how to obtain the accurate degree of stenosis, that is, How to get the accurate degree of vascular calcification. [0003] Because the calcified part of the blood vessel will be very brightly excited by the X-ray during the enhanced scan, the bright light will also illuminate the surrounding blood vessel tissue very brightly, thus bringing about calcification artifacts, which greatly affects the judgment of the degree of calcification. Generally, clinicians will calculate the actual d...

[0003] Because the calcified part of the blood vessel will be very brightly excited by the X-ray during enhanced scanning, the bright light will also illuminate the surrounding blood vessel tissue very brightly, thus bringing about calcification artifacts, which greatly affects the judgment of the degree of calcification

Generally, clinicians will calculate the actual degree of calcification by subtracting the results of judgment by naked eyes, etc., but this method has large errors and is not suitable for automatic judgment by computer
