Multi-modal medical image registration fusion method and device and electronic equipment

Abstract

The invention provides a multi-modal medical image registration fusion method and device and electronic equipment. The method comprises the following steps: acquiring two-dimensional medical images of at least two modals of a patient; respectively inputting the two-dimensional medical images of the at least two modalities into a pre-trained corresponding image segmentation network model so as to respectively obtain the output of the two-dimensional medical image of each modal body position area; and performing three-dimensional reconstruction on the two-dimensional medical image of each modal body position area, and then performing point cloud registration fusion to obtain a multi-modal fused three-dimensional medical image. The method is high in image registration precision, low in time cost, capable of processing complex multi-modal fusion conditions, capable of being applied to non-rigid registration conditions, accurate in registration result and capable of providing accurate treatment reference basis for medical staff.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a multimodal medical image registration and fusion method, device and electronic equipment. Background technique [0002] Medical image registration technology is aimed at two medical images from the same imaging device at different times or collected by different imaging devices, using one of the images as a reference to find one or a series of spatial transformation relationships, so that the other image is passed through After the space transformation, the corresponding points between the two images are basically consistent in space. Medical image registration technology has very important application value in clinical medicine. It integrates the complementary information expressed by different images for the reference of medical staff to improve the accuracy of clinical diagnosis. [0003] In the process of modern digital medical diagnosis, medical staff usu...
