Abstract
A method and device for real-time mechanical and dosimetric quality assurance measurements in radiation therapy provides a unified measurement of mechanical motion and radiation components of the machine. The device includes an imaging surface for receiving multiple energy sources. The imaging surface has an imaging plane positioned on a same plane as an isocenter of a medical accelerator. A camera measures and records data related to the multiple energy sources. A mirror system can be used to direct the multiple energy sources to the camera for further processing. However, in some instances the mirror system may not be necessary. Accordingly, a single device can be used to unify the measurement of mechanical motion and radiation component of the machine. The device can also include computer control in order to automate the movement of the device and/or automation of the QA protocol.
