Abstract: The present disclosure relates to the acquisition of image data over an extended field of view using an interventional tomosynthesis system. In one embodiment, the interventional tomosynthesis system has a base offset from the longitudinal axis of a patient table, such that movement of the table relative to the imager may be performed during tomosynthesis projection acquisition. One or both of the imager and the table may move to accomplish such relative motion.

Abstract: A radiation dose received by a patient from a radiation therapy system can be verified by acquiring a cine stream of image frames from an electronic portal imaging device (EPID) that is arranged to detect radiation exiting the patient during irradiation. The cine stream of EPID image frames can be processed in real-time to form exit images providing absolute dose measurements at the EPID (dose-to-water values), which is representative of the characteristics of the radiation received by the patient. Compliance with predetermined characteristics for the field can be determined during treatment by periodically comparing the absolute dose measurements with the predetermined characteristics, which can include a predicted total dose in the field after full treatment and/or a complete irradiation area outline (CIAO). The system operator can be alerted or the irradiation automatically stopped when non-compliance is detected.

Abstract: According to an embodiment, an X-ray computed tomography apparatus includes reconstruction circuitry and control circuitry. The reconstruction circuitry is configured to, at the time of the monitoring scan, based on an output of an X-ray detector for detecting X-rays having passed through the object, reconstruct a first image concerning the object at the time of administration of the contrast medium and a second image concerning the object after a predetermined period elapses since administration of the contrast medium. The control circuitry is configured to shift from the monitoring scan to the actual scan based on a change amount of a CT value obtained when the entire reconstructed first image is compared with the entire reconstructed second image.
