摘要：
The present disclosure relates to a device, a system, and a computer-readable medium for calculating vessel flow parameters based on angiography. In one implementation, the device includes a processor and a memory storing computer-executable instructions that, when executed by the processor, cause the processor to perform the following operations: selecting a plurality of template frames from the angiographic images to generate a 3D model for a vessel； determining a start frame and an end frame in the plurality of angiographic images showing a contrast filling process； determining corresponding locations of front ends of the contrast in the start frame and the end frame in the 3D model of the vessel； calculating a vessel volume between the determined locations of the front ends in the 3D model； and determining an average blood flow rate based on the calculated volume, and a time interval between the start frame and the end frame.
