公开了一种用于控制多切片计算机断层摄影系统(1)MSCT的图像采集的设备(10)。所述设备包括用于接收来自MSCT(1)的投影图像数据的输入端(11)、用于控制MSCT(1)的操作的输出端(12)以及处理器(13)。所述处理器(13)适于控制所述MSCT以采集大体积定位器射线照片，并且适于在所述定位器射线照片中定义界定感兴趣器官的器官区域。所述处理器适于采集对象的大体积螺旋CT扫描，其中，当所述对象中的所述器官区域被平移到检查体积中时，增加X射线锥角，并且当所述器官区域被平移出所述检查体积时，减小X射线锥角。 A device (10) for controlling an image acquisition of a multi-slice computed tomography system (1), MSCT, is disclosed. The device comprises an input (11) for receiving projection image data from the MSCT (1), an output (12) for controlling operation of the MSCT (1) and a processor (13). The processor (13) is adapted for controlling the MSCT to acquire a localizer radiograph, and for defining an organ region in the localizer radiograph that delimits an organ of interest. The processor is adapted for acquiring a helical CT scan of the subject, in which an X-ray cone angle is increased when the organ region in the subject is translated into the examination volume and decreasing the X-ray cone angle when the organ region is translated out of the examination v
