Dosimetric verification of compensated beams using radiographic film [PDF]

Radiology and Oncology, 2011
External photon beam modulation using compensators in order to achieve a desired dose distribution when brachytherapy treatment is followed by external beam radiation is a well-established technique. A compensator modulates the central part of the beam, and the dose beneath the thickest part of the compensator is delivered mostly by scattered, low ...
