The invention relates to the technical field of image processing, in particular to a medical image registration method, medical equipment and a storage medium. The method comprises the steps: obtaining a reference medical image sequence of a target part and a to-be-registered medical image sequence; determining a blood vessel boundary in each image layer of the to-be-registered medical image sequence to obtain a boundary sub-graph of each image layer; performing blood vessel boundary sampling on at least one image layer of the reference medical image sequence and at least one image layer of the to-be-registered medical image sequence to obtain a first boundary point set and a second boundary point set; determining optimal transformation based on offsets of corresponding boundary points inthe first boundary point set and the second boundary point set; and adjusting each boundary sub-image according to the optimal transformation so as to register the to-be-registered medical image sequence. And the optimal transformation acts on the boundary sub-graph, so that the offset of the blood vessel position in the image caused by displacement, respiration and the like in the scanning process can be counteracted.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a medical image registration method, medical equipment and a storage medium. Background technique [0002] Medical image registration is an important and complex task in the field of image processing research, because medical images come from different acquisition devices, different scanning times, different shooting angles, different research objects, etc. Therefore, it is often necessary to perform image registration before performing subsequent processing steps such as image fusion and image segmentation to achieve the same anatomical structure corresponding to the same position in space in different acquired images. [0003] Traditional image registration methods mainly include feature-based methods, which often need to use edge, surface, pixel and other information for feature extraction. The success of registration depends largely on the extracted features. This l...
