摘要：
A system is provided that includes a gantry, detector units, and at least one processor. The gantry defines a bore. The plural detector units are mounted to the gantry and configured to rotate as a group with the gantry in rotational steps. Each detector unit is configured to acquire imaging information while sweeping about a corresponding axis. The at least one processor is configured to determine a region of interest (ROI) of an object； identify a set of detector units； for the identified set of detector units, determine a sweeping configuration that results in a predetermined percentage of projection pixels receiving information from the ROI； determine a rotational movement configuration for the gantry using the determined sweeping configuration； and control the gantry and the set of detector units to utilize the determined rotational movement and sweeping configurations during acquisition of imaging information.
