Abstract

The invention relates to a medical image registration method, an electronic device and a storage medium. The method comprises the following steps of: acquiring an initial floating image and a reference image; gridding the initial floating image and the reference image to obtain an initial control grid; extracting matching feature point pairs from the initial floating image and the reference image,and determining the initial displacement of the matching feature point pairs; determining the initial displacement of a control point in the initial control grid according to the initial displacementof the matching feature point pairs in the initial control grid; and performing B-spline transformation-based image registration on the initial floating image and the reference image according to theinitial displacement of the control point in the initial control grid. Through the medical image registration method, the electronic device and the storage medium of the invention, the problem of lowregistration precision of medical images in related technologies is solved, and the image registration precision is improved.

Description

technical field [0001] The present application relates to the field of image registration, in particular to a medical image registration method, electronic device and storage medium. Background technique [0002] With the development of computer technology and biomedical engineering, medical imaging technology provides various types of medical images for clinical diagnosis, such as computed tomography images, nuclear magnetic resonance images, positron emission computed tomography images, single photon emitters, etc. Different medical imaging technologies are used to provide information about different organs and tissues of the human body, such as tomographic images, functional magnetic resonance images, cone beams, ultrasound images, digital subtraction vascular images, X-ray computerized tomography vascular images, etc. When using medical imaging equipment to scan human organs and tissues, due to the voluntary or involuntary physiological movement of the organs and tissues...
