AI Technical Summary
Technical Problem
Existing technologies, when scanning at times when the heart is least active, can only obtain medical images of the heart in one state of motion, resulting in insufficient diagnostic information for doctors and low diagnostic accuracy.
Method used
By acquiring coronary artery image quality index data, the first and second cardiac phases of multiple cardiac phases are selected, which are located in different motion stages of cardiac systole and diastole, respectively, to reconstruct coronary medical images of multiple cardiac phases.
Benefits of technology
It improves the accuracy of doctors' diagnosis based on coronary artery manifestations under various motion conditions, and enhances image quality and the reliability of diagnostic results.

Abstract
This specification provides a cardiac phase selection method and a medical imaging method. The cardiac phase selection method includes: acquiring coronary artery image quality index data from a coronary artery image dataset, wherein the coronary artery image quality index data quantifies the medical image quality of the coronary arteries of an examined object at multiple cardiac phases; selecting a first cardiac phase from the multiple cardiac phases based on the coronary artery image quality index data, wherein the first cardiac phase is within a first phase range; and selecting a second cardiac phase from the coronary artery image quality index data, wherein the second cardiac phase is within a second phase range different from the first phase range. This specification embodiment can select multiple cardiac phases, thereby facilitating the acquisition of medical images at multiple cardiac phases.
