Abstract
A system for tracking tumors during radiotherapy by interleaving treatment pulses with imaging pulses is disclosed. The system includes a multisource scanning eBeam X-ray tube having a plurality of focal spots. The X-ray tube is configured to emit X-rays to a plurality of different locations on a target by sequentially emitting the X-rays to the focal spots in the plurality of focal spots. This is done such that the X-rays can be emitted to the plurality of different locations on the target without substantially moving the X-ray tube or the target. The system further includes an imager panel configured to act as the target and configured to receive the X-rays from the focal spots of the X-ray tube. The system further includes a tomosynthesis reconstruction module configured to process output from the imager panel to construct an image.
