1. A method implemented on a computing device having a processor and a computer-readable storage device, the method comprising:
obtaining image data of a subject, the subject including at least one first vessel and at least one second vessel, wherein the at least one first vessel and at least one second vessel constitute a blood flow path;
generating a first vascular model and a second vascular model based on the image data of the subject, wherein the first vascular model and the second vascular model correspond to the at least one first vessel and the at least one second vessel, respectively;
coupling the first vascular model with the second vascular model using an intermediate model, wherein the first vascular model, the second vascular model, and the intermediate model form a coupled vascular model;
setting at least one of a first boundary condition of the first vascular model or a second boundary condition of the second vascular model;
determining a flow field distribution of the coupled vascular model based on the at least one of the first boundary condition of the first vascular model or the second boundary condition of the second vascular model; and
determining at least one of a value of a first hemodynamic parameter of the at least one first vessel or a value of a second hemodynamic parameter of the at least one second vessel based on the flow field distribution of the coupled vascular model.
