Abstract:
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.

Claim (Index 19):
The method of  claim 18 , wherein determining the corresponding locations includes:\n extracting multiple patches along a central line of the vessel in the template frames; finding corresponding locations with a maximum correlation coefficient within a corresponding neighborhood in the start frame and the end frame based on the respective patches in the template frames to determine corresponding patches in the start frame and the end frame; and determining a patch not presenting the vessel in the corresponding patches in the start frame and the end frame and determining the corresponding locations of the front ends of the contrast in the start frame and the end frame in the template frames based on the determined patch.
