This invention provides a coronary CTA calcified plaque detection system, method, device, and medium based on a phantom, relating to the field of applied medical technology. In this embodiment, after adjusting the CT equipment, at least one CTA image of all plaque phantoms can be acquired. After acquiring the patient's coronary CTA, the area adjacent to the plaque location is analyzed by computer.
