Abstract
Rise times and fall times provided by a high voltage generator are controlled to maintain image quality during such scans. The rise and fall times are controlled by first measuring rise and fall times at each transition. Then, a closed-loop controller is used to adjust control parameters of the high voltage generator, based on an error determined from the measurement, to achieve substantially constant rise and fall times. This invention may be based on the implementation of two closed-loop controllers on rise and fall time of fast-kV exposures. As a result, image quality may be improved and system calibration time may be reduced.
