An apparatus for calibrating an X-ray imaging system including: an X-ray source including a plurality of focal spots; a detector panel; and at least one planar structure including markers placed at pre-determined positions on the at least one planar structure, the at least one planar structure configured to estimate a position of the plurality of focal spots with respect to the detector panel.

Geometric calibration of X-ray imaging systems

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.

Tumor tracing device with multiple scan tubes

Automatic threat detection of volumetric computed tomography (CT) data, including: extracting at least one 3-D object from the volumetric CT data; constructing a feature vector for each of the at least one 3-D objects; and classifying each 3-D object as one of a threat or benign object using the feature vector and a set of truth threat and benign objects.
