Problems solved by technology
However, the imaging depth of FT is relatively shallow, and generally only 2-3cm imaging targets can be distinguished; PET can distinguish deep targets well, but the imaging effect is poor for shallow targets such as subcutaneous tumors; CT can provide High-resolution structural images, but cannot detect early tumors, and PET and FT can just make up for such defects

The invention discloses a CT / FT / PET three-mode synchronous imaging device which comprises a horizontally-moving table, a detection bed, a disc-shaped CT machine frame, a PET / FT machine frame, an X-ray tube, an X-ray detector, four PET detection heads, a laser, a CCD camera, an X-ray collimator, a filter wheel and a computer for constructing an image processing platform, wherein the disc-shaped CT machine frame and the PET / FT machine frame rotate with the axis of a detected small animal as the central axis, and each PET detection head is composed of six PET basic detection units. The CT / FT / PET three-mode synchronous imaging device integrates the advantages of the CT imaging mode, the FT imaging mode and the PET mode, more comprehensive and more accurate function and structure information can be provided for small animal carrier research, and the detection performance of early-stage tumors can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of molecular imaging, in particular to a CT / FT / PET three-mode synchronous imaging device. Background technique [0002] Small animal in vivo research methods are widely used in various preclinical research fields such as tumor research and drug development, but small animal in vivo research must rely on imaging methods such as CT, PET, SPECT, and MRI. Single-modal imaging methods can only provide structural or functional images of small animals, which has great limitations. Therefore, the development of multi-modal imaging equipment has become a hot spot in the field of medical imaging equipment research. [0003] So far, several research teams and commercial institutions have developed a variety of multimodal systems for small animal research, such as Inveon PET / CT from Siemens Medical Devices, and GENISYS PET / CT commercialized by Sofie Biosciences developed by UCLA. In addition, there are dual-modal or tr...
