Elecrocardiographic gate control collecting image method for reducing coronary artery movement fake image

Abstract

The present invention discloses one gate controlled electrocardiographic image collecting method with reduced coronary artery motion fake image. It performs gate controlled electrocardiographic image acquisition in the lowest motion speed inside the heart beat period of the right coronary artery. The present invention obtains satisfactory image quality and has no coronary artery motion fake image radically.

Description

【Technical field】 [0001] The invention relates to an electrocardiographic gating image acquisition method for reducing coronary artery motion artifacts. 【Background technique】 [0002] Since EBCT was applied to the clinical examination of heart disease in 1984, people have always believed that the slowest point of coronary artery movement in one cardiac cycle (one heartbeat) is the mid-diastolic period, which is located near the p wave of the electrocardiogram, 70% to 80% Cardiac cycle, and 80% of the electrocardiogram cardiac cycle is fixedly applied to the time phase of the image acquisition, which cannot be changed in the software written into the EBCT computer image acquisition software. In practice, imaging is very difficult because the coronary artery moves very fast with the beating of the heart, and the lumen of the coronary artery is tortuous and small. When EBCT was used to scan the patient's heart, it was found that most patients' coronary artery images had motio...

[0002] Since EBCT was applied to the clinical examination of heart disease in 1984, people have always believed that the slowest point of coronary artery movement in one cardiac cycle (one heartbeat) is the mid-diastolic period, which is located near the p wave of the electrocardiogram, 70% to 80% Cardiac cycle, and 80% of the cardiac cycle of the electrocardiogram is fixedly applied to the time phase of the image acquisition, which cannot be changed in the software for EBCT computer image acquisition

In practice, because the coronary artery moves very fast with the beating of the heart, and the coronary lumen is tortuous and small, imaging is very difficult

When EBCT was used to scan the patient's heart, it was found that most patients' coronary artery images had motion artifacts, and the coronary arteries were "arc-shaped" instead of "dot-shaped", which caused the failure of the examination, and the coronary artery segments with motion artifacts could not be detected. make a diagnosis
