ProSPECTus项目是开发用于核医学成像应用的原型半导体康普顿相机。所提出的系统有可能通过使用电子准直技术来提高传统的机械准直单光子发射计算机断层扫描（SPECT）系统的灵敏度。此外，在磁共振成像（MRI）系统中使用兼容的半导体技术可能会导致SPECT/MRI数据采集的混乱。本文概述了新系统的主要设计特点的考虑。这种设计因素包括几何设置、探测器的合适能量和位置分辨率值以及系统在磁场中工作的能力。ProSPECTus原型成像系统现在将根据优化的规格进行构建。
The ProSPECTus project is the development of a prototype semiconductor Compton camera for use in nuclear medical imaging applications. The proposed system has the potential to improve the sensitivity of conventional mechanically col-limated Single Photon Emission Computed Tomography (SPECT) systems through the use of electronic collimation techniques. In addition, the use of compatible semiconductor technology within a Magnetic Resonance Imaging (MRI) system could potentially lead to simultanous SPECT/MRI data acquisition. This paper outlines the consideration of key design features for the new system. Such design factors include the geometrical setup, suitable energy and position resolution values for the detectors and the ability of the system to function in a magnetic field. The ProSPECTus protoype imaging system will now be built according to optimised specifications.
