摘要： 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.
