Title:
TRAINING METHOD AND APPARATUS FOR ANGIOGRAPHY IMAGE PROCESSING, AND AUTOMATIC PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/258835
Kind Code:
A1
Abstract:
A training method and apparatus for angiography image processing, and an automatic processing method and apparatus for vascular images. The training method for angiography image processing comprises: acquiring training data (S101), the training data including original angiography image data and local segmentation result data of side branch vessels, the local segmentation result data of side branch vessels being local segmentation image data, determined from an original angiography image, of side branch vessels on a main branch vessel; and training a neural network according to the acquired training data, so that the neural network performs local segmentation on side branch vessels, determined from the original angiography image, on the main branch vessel (S102). The training method for angiography image processing can obtain a neural network for performing local segmentation on side branch vessels, thereby improving the segmentation accuracy while increasing the segmentation efficiency, and avoiding missed segmentation and wrong segmentation of the side branch vessels.
