Control Means for Heat Load in X-Ray Scanning Apparatus

摘要

The present invention is an X-ray scanning system having at least one multi-focus X-ray tubes spaced around an axis and arranged to emit X-rays through an object on the axis. The emitted X-rays are detected by sensors. Each multi-focus X-ray tube can emit X-rays from a plurality of source positions. In an exemplary scanning cycle, each of the source positions in each X-ray tube is used at least once and ordered to minimize the thermal load on the tubes.
