FastSPECT II是最近委托使用的16摄像头小动物SPECT成像仪，配备了模块化闪烁相机和列表模式数据采集电子设备。该仪器安装在铅屏蔽外壳中，并具有可更换的光圈组件和可调整的相机位置，以选择放大倍数、针孔大小和视场。通过五轴运动控制系统支持单个相机的校准和整个系统成像矩阵(1 mm(3)体素)的测量。系统集成的细节以及表征和性能测量的结果与第一张断层图像一起提供。对仪器的动态成像能力进行了探讨和讨论。
FastSPECT II is a recently commissioned 16-camera small-animal SPECT imager built with modular scintillation cameras and list-mode data-acquisition electronics. The instrument is housed in a lead-shielded enclosure and has exchangeable aperture assemblies and adjustable camera positions for selection of magnification, pinhole size, and field of view. The calibration of individual cameras and measurement of an overall system imaging matrix (1 mm(3) voxels) are supported via a five-axis motion-control system.Details of the system integration and results of characterization and performance measurements are presented along with first tomographic images. The dynamic imaging capabilities of the instrument are explored and discussed.
