Novel Detector for Small Animal SPECT Imaging

核医学技术（如SPECT）有可能成为强大的新工具，在小型实验室动物的生物过程成像。随着人类疾病模型的不断增加，特别是在小鼠和大鼠等较小动物中，高分辨率核医学核医学技术提供独特信息的潜力对许多研究人员来说变得越来越明显。临床放射性核素系统不适用于小动物成像，因为它们的空间分辨率不够。这使得商业SPECT系统不适合于成像小动物，因为它们的空间分辨率不够。这使得商业SPECT系统不适合分辨小鼠中毫米大小的结构。因此，需要专用的低成本仪器来进行小动物研究，其空间分辨率高于目前临床SPECT扫描仪所实现的空间分辨率。提出的研究的目标是调查一种新的位置敏感探测器的概念，小动物SPECT成像。所提出的方法预计将提供高的空间分辨率，该系统预计将更简单，成本更低，相比其他方法正在调查。核医学包括正电子发射断层扫描和单光子发射计算机断层扫描，放射学，无损检测，材料研究，X射线衍射，核和高能物理研究，天文学和地质勘探。

Nuclear medicine techniques (such as SPECT) have the potential to become powerful new tools in imaging biological processes in small laboratory animals. With the every increasing number of human disease models, particularly in the smaller animals such as mice and rats, the potential of high resolution nuclear medicine nuclear medicine technologies to contribute unique information is becoming apparent to many researchers. Clinical radionuclide systems are not suitable for imaging small animals because their spatial resolution is not adequate. This makes commercial SPECT systems are not suitable for imaging small animals because their spatial resolution is not adequate. This makes commercial SPECT systems unsuitable for resolving millimeter- sized structures in mice. Hence, dedicated, low cost instruments are required for conducting small animal studies with higher spatial resolution than what is current achieved with clinical SPECT scanners. The goal of the proposed research is to investigate a novel position sensitive detector concept for small animal SPECT imaging. The proposed approach is expected to provide high spatial resolution, and the system is expected to be simpler and lower in cost as compared to other approaches being investigated.
