    • An imaging system is provided for radioimaging a region of interest (ROI) of a subject. The system includes a housing, a support structure, which is movably coupled to the housing, and at least one motor assembly, coupled to the housing and the support structure, and configured to move the support structure with respect to the housing. The system also includes at least two detector assemblies, fixed to the support structure, and comprising respective radiation detectors and angular orientators. A control unit drives the motor assembly to position the support structure in a plurality of positions with respect to the housing, and, while the support structure is positioned in each of the plurality of positions, drives the orientators to orient the respective detectors in a plurality of rotational orientations with respect to the ROI, and to detect radiation from the ROI at the rotational orientations. Other embodiments are also described.
    • 提供了一种用于对受试者的感兴趣区域(ROI)进行放射成像的成像系统。 该系统包括壳体,可移动地联接到壳体的支撑结构,以及联接到壳体和支撑结构并且被配置为使支撑结构相对于壳体移动的至少一个马达组件。 该系统还包括固定到支撑结构的至少两个检测器组件,并且包括相应的辐射检测器和角定向器。 控制单元驱动马达组件以将支撑结构定位在相对于壳体的多个位置中,并且当支撑结构位于多个位置中的每一个位置时,驱动取向器以将各个检测器定向成多个 相对于ROI的旋转取向,并且以旋转取向检测来自ROI的辐射。 还描述了其它实施例。
