Electron Beam Quality Parameters and Absorbed Dose Distributions from Therapy Accelerators

  • A. Brahme

The quality of therapeutic electron beams is often specified by one single parameter, namely, the energy as determined from the practical range. However, the practical range is a parameter which is generally not directly related to the therapeutically useful part of the absorbed dose distribution. Therefore, further parameters are needed [1] to obtain a specification of the beam quality which is more relevant from a therapeutic point of view and, at the same time, simple.
