Calcified artifact eliminating method and equipment and computer storage medium

Abstract

The invention discloses a calcified artifact elimination method and device and a computer storage medium, and the method comprises the steps: obtaining and processing original blood vessel image data,and obtaining original calcified image data; carrying out fitting processing on the original calcified image data to obtain a gray scale change curved surface; extracting the original calcified imagedata according to the gray scale change curved surface to obtain a calcified center area image; and adjusting according to the calcification center area image to obtain an artifact correction calcification image. According to the embodiment of the invention, an original image is subjected to primary calcification region extraction; gray scale fitting is carried out on original calcified area image data to obtain a gray scale change curved surface, artifact influence is eliminated again through the gray scale change curved surface, a more accurate artifact correction calcified image method isobtained, the influence effect of calcified artifacts is better eliminated, and a more accurate calcified calculation result can be obtained.

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
