Abstract
A radiation therapy system delivers radiation treatment over a 360-degree arc and performs a prepended imaging process, in a single pass, via an extended rotation gantry. While rotating the gantry in one direction about a bore of the radiation system, the radiation system generates multiple images of a target volume disposed in the bore using an imaging X-ray source mounted on the gantry. Then, while continuing to rotate the gantry in the same direction, the radiation system delivers a treatment beam to the target volume using a treatment-delivering X-ray source mounted on the gantry, where the treatment beam is delivered from some or all of a 360-degree arc about the bore. Thus, the prepended imaging process and the delivery of radiation are performed in a single pass of the gantry about a target volume, eliminating the need for a return stroke of the gantry for completion.
