Abstract: A system for tracking tumors during radiotherapy for interleaving treatment pulses with imaging pulses is disclosed. The system includes a plurality of multisource scanning eBeam X-ray tubes, each having multiple focal spots. The X-ray tubes are configured to emit X-rays in a plurality of different locations on a target by sequentially emitting the X-rays to the focal spots in the different focal spots. This is done such that the X-rays can be emitted to the plurality of different locations without substantially moving the X-ray tube or the target. The system further includes multiple imager panels configured to act as targets 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 outputs from the imager panels to construct a unified three-dimensional image that takes information from each of the different imager panels.
