Abstract
A radiotherapy system includes a radiotherapy device, such as a LINAC, operable to direct a radiation beam from a head thereof during operation, a field detector positioned to be within the radiation beam during operation of the radiotherapy device and operable to generate a beam measurement signal, a reference detector positioned to be outside of the radiation beam during operation of the radiotherapy device and operable to generate a reference signal, and at least one computer in signal communication with the field detector and the reference detector and configured with software to normalize the beam measurement signal based on the reference signal and to output a normalized beam measurement.
