Problems solved by technology

These two types of imaging methods have their own advantages and disadvantages. The spatial resolution of anatomical structure imaging is high, which can provide information on the anatomical shape of the human body; the spatial resolution of functional imaging is low, but it can provide functional information on the internal organs and brain of the human body; The information provided by the same type of imaging method is not exactly the same. For example, in structural imaging, CT can clearly display the structural image of bones, and MRI is suitable for imaging soft tissue morphology. Therefore, imaging methods of different modalities can provide morphological and functional information. complementary information

specific Embodiment approach

[0054] Specific embodiments: the method of using the present invention is described only by taking the head image registration of MRI and CT images as an example.

[0055] With the continuous development of medical imaging technology, more and more imaging methods have emerged, and are widely used in the research of brain cognitive function and medical clinical diagnosis and treatment. Due to different imaging principles and equipment, there are many imaging modes, which mainly include anatomical structure imaging modes (such as: CT, MRI, etc.) that describe physiological forms and functional imaging modes (such as: fMRI, PET, etc.) that describe human body functions or metabolism. SPECT, etc.) two categories. In brain function research and medical clinical diagnosis and treatment, for various reasons, it is usually necessary to perform multiple imaging of the same person or multiple people in multiple modes or the same mode, that is, to obtain information from several images ...

Abstract

The invention relates to a multiple modality medical image registration method based on mutual information sensitive range which mainly comprises, extracting mutual information sensitive area of the image information to be registered, then carrying out the registration of mutual information sensitive area through mutual information maximization, the invention can realize rapid and robust multiple modality medical image registration, and is especially suitable for multiple modality head image registration.

Description

technical field [0001] The invention relates to the technical field of medical image analysis, in particular to a multimodal medical image registration method based on mutual information sensitive regions. Background technique [0002] With the continuous development of medical imaging technology, more and more imaging methods have emerged, and are widely used in the research of brain cognitive function and medical clinical diagnosis and treatment. Due to different imaging principles and equipment, there are many imaging modes, which mainly include anatomical structure imaging modes describing physiological forms (such as: computer-aided X-ray tomography (CT), magnetic resonance imaging (MRI), etc.) and describing human body functions Or metabolic functional imaging modalities (such as: single photon emission tomography (SPECT), positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), etc.). These two types of imaging methods have their own advan...
