Abstract
The present disclosure provides a method for evaluating a hemodynamic characteristic, comprising: obtaining a medical image of a subject, the medical image including at least a portion of a vascular structure; determining at least one property parameter of the vascular structure by inputting the medical image into a trained parameter determination model; and determining at least one hemodynamic characteristic of the vascular structure by inputting the at least one property parameter into a vascular fluid dynamic model.
