A medical nuclide imaging system and imaging method based on photosensitive tights

Abstract

The invention discloses a medical nuclide imaging system and a medical nuclide imaging method based on photosensitive tights. The imaging system comprises an imaging darkroom, three CCD cameras, a control system, a lifting system and the photosensitive tights, wherein the photosensitive tights are prepared by uniformly mixing acrylic fibers and Gd2S2O (gadolinium oxysulfide) rare earth material. During the imaging process, a to-be-tested person receives intravenous injection of corresponding radionuclide, then enters the imaging darkroom for imaging at the proper moment, after lighting equipment inside the imaging darkroom is turned on, the to-be-tested person stands in an imaging area, and the three CCD cameras photograph the to-be-tested person; then the to-be-tested person stands still, the lighting equipment inside the imaging darkroom is turned off, the three CCD cameras collect fluorescence signals converted by the photosensitive tights and on the body surface of the to-be-tested person, and finally a fluorescence signal image and a picture image are displayed in a mixing manner. With the adoption of the medical nuclide imaging system and the medical nuclide imaging method, optical imaging of the medical radionuclide is realized, and the medical nuclide imaging system and the medical nuclide imaging method have the characteristics of whole body imaging, real-time imaging, simplicity and convenience in operation, low cost, and the like.

Description

technical field [0001] The invention relates to the technical field of biomedical molecular imaging, and mainly relates to an imaging system and method for detecting medical radionuclides using optical equipment. Background technique [0002] Nuclide imaging is a kind of science that uses nuclides and their labeled compounds for clinical diagnosis and biological research. It is an important part of modern medicine and has a huge impact on the development of medicine. It is based on nuclide tracer technology, based on the difference in the absorption function of biological tissues, and takes the radioactive concentration as the reconstruction variable. After introducing radionuclide-labeled molecules into the body, it detects and records the target tissue or target organ in the body. Gamma rays emitted by a radioactive tracer and displayed as an image. It can not only display the anatomical structure such as the location, shape, and size of organs or lesions, but more import...
