Abstract: A radiation therapy system that includes a radiation source that moves about a path and directs a beam of radiation towards an object and a cone-beam computer tomography system. The cone-beam computer tomography system includes an x-ray source that emits an x-ray beam in a cone-beam form towards an object to be imaged and an amorphous silicon flat-panel imager receiving x-rays after they pass through the object, the imager providing an image of the object. A computer is connected to the radiation source and the cone beam computerized tomography system, wherein the computer receives the image of the object and based on the image sends a signal to the radiation source that controls the path of the radiation source.

Abstract: Various embodiments are described herein for an area integrated fluence monitoring sensor that can be used to measure a radiation dose. The sensor comprises at least one Gradient Ion Chamber (GIC) comprising an ion chamber having a volume gradient across a length or width thereof, a gas or liquid located within the ion chamber and an electrode to detect ions generated within the gas or liquid when the at least one GIC is subjected to an ionizing radiation beam. Various embodiments are also described herein for an Integral Quality Monitoring system and associated method that can be used to measure and monitor the quality of radiation doses provided by a radiation treatment system.
