A generic off-axis energy correction for linac photon beam dosimetry

Cooperative clinical trial group protocols frequently require off-axis point dose calculations. The Radiological Physics Center uses the calculative technique developed by Hanson et al. [Med. Phys. 7, 145–146 (1980); 7, 147–150 (1980)] to verify these calculations. In order to correct for off-axis e...
