Abstract
Exemplary embodiments of the present invention provide a CT imaging method of coronary artery and a computer-readable storage medium, the method comprising: generating and outputting a global optimal phase image of a coronary artery; and generating and outputting a local optimal phase image of a particular trunk of the coronary artery based on a trunk selection command.
Claims14
A computed tomography (CT) imaging method of a coronary artery, comprising:
- collecting, via a CT imaging system, image data of the coronary artery;
- obtaining motion indexes of each trunk of the coronary artery at different phases based on the collected image data;
- obtaining an average curve of the motion indexes of a plurality of trunks of the coronary artery, wherein a horizontal axis represents each phase and a vertical axis represents each of the motion index;
- determining a corresponding global optimal phase based on the average of the motion indexes, wherein the global optimal phase is the phase corresponding to the highest motion index;
- performing image reconstruction based on the image data at the global optimal phase thereby generating a global optimal phase image of the coronary artery;
- outputting the global optimal phase image;
- and
- generating and outputting a local optimal phase image for a particular trunk of the coronary artery based on a trunk selection command.
A non-transitory computer-readable storage medium for storing a computer program when installed in a computer system of a computed tomography (CT) imaging system for causing the computer system to:
- collect, via the CT imaging system, image data of the coronary artery;
- obtain motion indexes of each trunk of the coronary artery at different phases based on the collected image data;
- obtain an average curve of the motion indexes of a plurality of trunks of the coronary artery, wherein a horizontal axis represents each phase and a vertical axis represents each of the motion index;
- determine a corresponding global optimal phase based on the average of the motion indexes, wherein the global optimal phase is the phase corresponding to the highest motion index;
- perform image reconstruction based on the image data at the global optimal phase thereby generating a global optimal phase image of the coronary artery;
- output the global optimal phase image;
- and
- generate and output a local optimal phase image fora particular trunk of the coronary artery based on a trunk selection command.
