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 25):
The method of  claim 24 , wherein determining the start frame and the end frame includes at least one of:\n determining the start frame and the end frame such that the contrast filling process between the start frame and the end frame passes through the entire segment without any branch; and setting an inlet marker near a start point and an outlet marker near an end point of the segment in the angiographic images, and automatically selecting the start frame and the end frame by analyzing variations of pixel values near the inlet marker and the outlet marker over time.
