Abstract
A quality assurance device for a medical accelerator includes a housing having an inner radioluminescent layer adapted to provide a visual indication when contacted with invisible radiation generated by the medical accelerator. In addition, the quality assurance device includes one or more passive optical components within the housing adapted to deliver an image of the inner radioluminescent layer of the housing including the visual indication to one or more cameras located outside of the housing.

A quality assurance device for a medical accelerator, comprising:
- a housing having an inner radioluminescent layer adapted to provide a visual indication when contacted with invisible radiation generated by the medical accelerator;
- at least one camera located outside of the housing;
- and
- at least one passive optical component, located within said housing, adapted to deliver an image of the inner radioluminescent layer of said housing including the visual indication to said at least one camera located outside of said housing.
A method of quality assurance for a medical accelerator, comprising:
- positioning a quality assurance device on a treatment couch of the medical accelerator;
- detecting radiation delivered by the medical accelerator to the quality assurance device by producing a visual indication of the radiation on an inner layer of a housing of the quality assurance device;
- delivering an image of the visual indication from at least one passive optical device within the housing to at least one camera located outside of the housing;
- and
- imaging the visual indication with the at least one camera.
