Problems solved by technology

Most of the existing technologies are dual-mode imaging systems, such as the combination of nuclide and fluorescence, CT and PET, and CT and fluorescence. resolution requirements, and the existing fluorescence and nuclide imaging systems generally achieve 360° data acquisition by rotating the animal body or rotating the imaging system frame. Due to the long acquisition time of a single image data, it is not conducive to observation Rapid dynamic changes of cellular and molecular events

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 As shown, the present invention includes a body, and a support frame is arranged in the body, and a fluorescence imaging system 1, a nuclide imaging system 2, an X-ray imaging system 3 and a transmission device are arranged on the support frame. The fluorescence imaging system 1 and the nuclide imaging system 2 are geometrically arranged orthogonally, and the two imaging systems simultaneously collect the functional data of the small animal body to complete the functional imaging of the small animal body. The X-ray imaging system 3 is arranged side by side with the fluorescence imaging system 1 and the nuclide imaging system 2 and forms images asynchronously with the fluorescence imaging system 1 and the nuclide imaging system 2, and collects the structural data of the small animal to complete the structural imaging of the small a...

Description

technical field [0001] The invention relates to an imaging system, in particular to a small animal imaging system which integrates three modes of fluorescence, nuclide and X-ray for modern biology and medical research. Background technique [0002] Molecular imaging technology can provide visualization means for observing cells, molecular events and their dynamics, and it has become an important tool in the fields of biology, medicine and new drug development, and small animals are the main experimental means of modern biology and medical research , therefore, small animal image detection has become a hotspot in molecular imaging research. Fluorescence tomography (FMT) is an optical molecular imaging technique that can be used for quantitative analysis in living organisms. The application of molecular-specific fluorescent probes to body detection can achieve non-invasive and visualized biological, chemical and physical studies. Behavior. Positron emission tomography (PET) ...
