  • Method and system for indexing blood vessel corresponding positional relations in multi-angle angiography
    Patent number: 11132815
    Abstract: A system and method for retrieving a blood vessel corresponding positional relation under multi-angle angiography. The system includes an angiography machine, an angiographic image receiving module, a center point calibration module, a corresponding feature point detection module, and a feature point corresponding blood vessel module. The angiography machine is used for performing angiography and collecting angiographic images of multiple projection body positions. The angiographic image receiving module is used for receiving an angiographic image and transmitting the angiographic image to the center point calibration module. The center point calibration module is used for calibrating a center point offset caused by the multi-angle angiography system and transmitting the result to the feature point detection module.
