  • Publication number: 20140348288
    Abstract: A system for tracking tumors during radiotherapy for 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 in 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 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.

  • Patent number: 8625738
    Abstract: A radiation therapy and scanning system is provided. The radiation and therapy scanning system includes a therapy source adapted to deliver a predetermined dose of treatment radiation along an axis to a patient positioned in a scan field, a stationary scanning source producing an electron beam, and a detector positioned to partially circumscribe the scan field. The radiation therapy and scanning system also includes a target arranged concentric with the detector and located opposite the detector across the scan field, the target positioned at an angle ? to the axis such that when the electron beam impinges on the target the target transmits radiation through the scan field to the detector.

  • Patent number: 8530849
    Abstract: An electron beam scanner includes a stationary source producing an electron beam and a detector positioned to partially circumscribe a scan field, the detector divided into a pair of detector rings arranged adjacent to one another and separated by a gap extending at least partially about a circumference of the detector. The electron beam scanner also includes a target arranged concentric with the detector and located opposite the detector across the scan field, the target having end portions circumferentially overlapping the detector and radially aligned with the gap between the detector rings, such that when the electron beam impinges on the target the target transmits radiation through the gap across the scan field to an associated section of the detector.

  • Patent number: 7872241
    Abstract: An electron beam production and control assembly includes a vacuum chamber, a beam source, and a target. The target has an active section and an inactive section. The active section is adapted to generate x-rays when the beam impinges on the x-ray producing section. The electron beam production and control assembly also includes a focusing unit positioned along the chamber at a location intermediate the rearward end and the forward end. The focusing unit directs the beam towards the target in a converging manner to impinge on the target. The focusing unit sweeps the beam along a scanning path over the active section of the target. The focusing unit moves the beam to a retrace path on the inactive section of the target between sweeps of the scanning path to maintain ion accumulation in the beam between sweeps over the active section.
