The invention provides a system and a method for fusing an image of positron emission tomography (PET) and an image of magnetic resonance imaging (MRI), belonging to medical equipment field. The system comprises: a magnetic resonance scanner (MRS) for generating the image of the MRI; a positron emission tomographic scanner (PETS) for generating the image of the PET, wherein an angle between a center line of a patient aperture of the PETS and a center line of a patient aperture of the MRS is [phi]; a rotatable patient inspection bed disposed between the PETS and the MRS; and a piece of operation equipment used for controlling imaging of PETS and MRS, storing, displaying and utilizing a position relationship between tomographic images to fuse the image of the MRI and the image of the PET, and controlling rotation and movement of the patient inspection bed. The system and the method using a technical scheme in the invention can realize fusion of the image of the PET and the image of the MRI on the same machine.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a system and method for fusing positron emission tomography images and magnetic resonance scan images. Background technique [0002] PET-CT (Positron Emission Computed Tomography-computed tomography, Positron Emission Tomography-computed tomography) integrates CT and PET. CT provides precise anatomical location of lesions, while PET provides detailed function and metabolism of lesions. Such molecular information has the characteristics of sensitivity, accuracy, specificity and precise positioning. One imaging can obtain tomographic images of all directions of the whole body, and can understand the overall condition of the whole body at a glance, so as to achieve the purpose of early detection of lesions and diagnosis of diseases. The emergence of PET-CT is another revolution in medical imaging, which has been recognized and widely concerned by the medical community. The fusion of ...
