Method for synchronizing time sequence accelerating voltages of X-ray tube and time sequence selection process of detector in tube detector system of computed tomography-system, involves adjusting time sequence of accelerating voltages

摘要

The method involves adjusting a time sequence of accelerating voltages (U1,U2) and time sequence of selection process (A1,A2) relatively to each other. An image value difference criterion is optimized by the adjustment of time sequences. The time sequence is periodically changed between two voltage levels of an X-ray tube. An independent claim is also included for a computed tomography-system, which has a controlling and computing unit.
