Abstract
An apparatus has a patient support, a rotatable gantry supporting a source of imaging radiation, and a radiation detector that operates in a cyclical pattern of an exposure phase followed by a readout phase. For a first detector cycle in which the gantry has a first angle of rotation, the source of radiation is controlled to emit a first radiation beam pulse during the exposure phase, and respective first imaging data is read out during the readout phase. For a second, subsequent detector cycle, it is determined if the gantry has rotated through at least a threshold angular displacement relative to said first angle of rotation, and if so, the source of radiation is controlled to emit a second radiation beam pulse during the exposure phase, and respective second imaging data is read out during the readout phase.
