MRI/PET/CT/PET-CT panoramic video auxiliary system

Abstract

The invention provides an MRI / PET / CT / PET-CT panoramic video auxiliary system which is applied in scanning detection of MRI, PET, CT, PET-CT and the like to acquire and monitor human pose states on a scanning bed in a scanning rack hole in real time. The system comprises a video synchronous acquisition module composed of multiple wide-angle cameras and a pose adjusting device thereof, a video preprocessing module for performing video distortion correction processing, a video splicing module for performing fusion splicing on video overlapping areas, a video storage module for storing spliced videos and a video display module for displaying the spliced videos. According to the system, GPU parallel computing multi-thread control is adopted, and video acquisition, preprocessing, splicing, display and storage are carried out by using a translation and variable diameter rotation composite motion model. The system can meet direct and complete observation of body position change when a doctor scans a patient.

Description

technical field [0001] The invention relates to the field of MRI / PET / CT / PET-CT auxiliary technology, in particular to an MRI / PET / CT / PET-CT panoramic video auxiliary system. Background technique [0002] CT (Computed Tomography), computerized tomography. Using computer technology to reconstruct the tomographic image of the measured object to obtain a three-dimensional tomographic scanning method. [0003] PET (positron emission tomography), positron emission tomography. Human metabolites such as glucose labeled with positron nuclides are used as imaging agents, and the metabolic changes of imaging agents are reflected through the uptake of imaging agents by lesions, thereby providing clinical biological metabolism information of diseases. [0004] PET-CT combines PET and CT organically, and uses the same examination bed to share an image workstation. PET / CT has the functions of PET, CT and fusion of PET images and CT images at the same time. [0005] MRI (Magnetic Resonanc...

Problems solved by technology

When performing these tests, patients need to keep a specific position during the scanning time, otherwise it will lead to artifacts, which will affect the test results and affect the diagnosis

When the patient enters the scanning frame hole with the scanning bed for scanning, it is difficult for the doctor to observe the patient's scanning status, such as whether the patient's initial body position is adjusted properly, whether the patient's body position has changed, or the patient is alone.
