Abstract
A method of radiation therapy comprises, while a gantry of a radiation therapy system rotates continuously in a first direction through a treatment arc from a first treatment delivery position to a second treatment delivery position, causing an imaging X-ray source mounted on the gantry to direct X-rays through a target volume and receiving a set of X-ray projection images from an X-ray imager mounted on the gantry; determining a current location of the target volume based on the set of X-ray projection images; and while the gantry to continues to rotate to the second treatment delivery position, initiating delivery of a treatment beam of a treatment-delivering X-ray source mounted on the gantry to the target volume, and continuing to cause the gantry to rotate in the first direction from the second treatment delivery position to a third treatment delivery position.
