Abstract
Time-domain interleaving of treatment X-rays and imaging X-rays during an image guided radiation therapy (IGRT) process in a radiation therapy system prevents scatter of the treatment X-rays from degrading the quality of X-ray images used to generate volumetric image data of a target volume. Imaging X-rays are delivered to the target volume during one or more imaging intervals, and one or more pulses of treatment X-rays are delivered to the target volume between the imaging intervals. In instances in which a pulse of treatment X-rays is timed to occur during an imaging interval, the pulse of treatment X-rays is inhibited from occurring during the imaging interval and is rescheduled to occur at a later time that does not coincide with that imaging interval or subsequent imaging intervals.
