CT (computed tomography)/FT (fluorescence tomography)/PET (position emission tomography) tri-modal synchronous imaging data acquiring system

Abstract

The invention discloses a CT (computed tomography)/FT (fluorescence tomography)/PET (position emission tomography) tri-modal synchronous imaging data acquiring system. The CT/FT/PET tri-modal synchronous imaging data acquiring system comprises a support device, a power device, a signal transmission device, a data acquiring device and a control system. During use, an examination bed is disposed in an imaging hole of the data acquiring device; a motor is controlled to operate according to a required mode by a control signal sent by a computer, and simultaneously, an X-ray tube, a laser, a CCD (charge coupled device) camera and a filter wheel are indirectly controlled by a control box; a disc rack surrounds a central line of the imaging hole to rotate around a small animal according to the set mode and acquires tri-modal data; acquired data are directly stored in the computer via a slip ring; the computer respectively processes the tri-modal data and rebuilds tri-modal images, and the tri-modal images are integrated into an image displaying an examined portion and functional information of the small animal via a specific processing algorithm. The tri-modal synchronous imaging data acquiring system integrates CT, optical and PET imaging modes into the same frame structure, so that three devices are controlled to acquire data by the same control system, and integration of the tri-model images is realized.

Description

Technical field [0001] The invention relates to the technical field of molecular imaging imaging, in particular to a data acquisition system that can realize CT / FT / PET three-modality synchronous imaging. Background technique [0002] Multimodal imaging technology is currently a hot spot in the field of medical imaging equipment research. Compared with single modalities such as CT (Computed Tomography), MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography) and other imaging technologies, multimodality Because of the integration of the advantages of multiple modal imaging technologies, the state imaging technology can provide more and more complete biological function and structure information at the same time, and has a wide range of applications in the related fields of biomedical research. [0003] So far, many research teams and commercial organizations have developed a variety of multi-modal imaging systems for human clinical research or small animal research, suc...
