On May 29th, an expert from the Planning and Finance Bureau of the Chinese Academy of Sciences organized an on-site acceptance of the research and development project for major scientific research equipment undertaken by the Institute of High Energy Physics, “γ-ray imaging system based on aperture coding technology†and “development of a small SPECT/CT systemâ€. .
The acceptance panel heard Wei Luong, head of the "Aperture Coding-based gamma ray imaging system" project, and Wang Baoyi, head of the "Development of a small SPECT/CT system" project, and the use report, financial report, and test panel test. The report, on-site verification of the operation of the development equipment, reviewed the relevant file files and financial accounts. The expert group highly appraised the development of the two projects, and considered that the technical indicators were at or better than the requirements of the implementation plan. The system reached the advanced level of similar international equipment, complete technical files, reasonable use of funds, and the unit’s self-financing funds were in place. Unanimously agreed to pass the acceptance.
Gamma Ray Imaging System Based on Aperture Coding Technology
The γ-ray imaging system based on aperture coding technology has the function of fusion of gamma ray imaging and optical imaging with large viewing angles and high efficiency. The nested coded aperture method and iterative decoding reconstruction algorithm are used to effectively achieve noise suppression in strong γ-ray backgrounds. Weak source imaging. The location registration algorithm for ray image and optical image under different object distance conditions was designed, and the fusion of the two images was realized. It can realize the positioning of radioactive materials at different distances. It plays an important role in searching for missing radioactive sources, determining radioactive contamination areas, and nuclear emergency monitoring. It has important application prospects in the fields of environmental protection, application of nuclear energy and nuclear technology, and nuclear anti-terrorism.
Small SPECT/CT System
The small SPECT/CT system has SPECT (single photon emission tomography), μCT (micro-CT), and image fusion capabilities to solve the "dead zone" problem of multi-detector measurement for small animal SPECT/CT imaging systems. Area, high resolution and position sensitive imaging technology. Implemented and solved SPECT and CT image reconstruction algorithms and image fusion engineering. It has high-resolution imaging capabilities for small animals, such as rats and mice, and provides technical means and research platforms for scientific research in nuclear medicine, pharmacology, biology, and other related fields. The research results will provide technical support for the development and clinical application of domestic SPECT/CT.
