The current UK code of practice for high-energy photon therapy dosimetry (Lillicrap et al 1990 Phys. Med. Biol. 35 1355-60) gives instructions for measuring absorbed dose to water under reference conditions for megavoltage photons. The reference cond

To estimate the benefit of introduction of image-guided radiotherapy (IGRT) to prostate radiotherapy practice with current clinical target volume-planning target volume (PTV) margins of 5-10 mm.Systematic error data collected from 50 patients were us

Cumulative dose-volume histograms of organs-at-risk are commonly used as predictors of the likelihood and severity of toxicity. In the case of hollow organs such as the rectum, the dose-volume histogram of the organ disregarding the lumen (dose-wall

The use of equivalent squares is of value when determining output and depth dose data for rectangular fields. We have looked at the variation with field shape of head scatter factors (S(c)), phantom scatter factors (S(p)) and tissue phantom ratios (T

The equivalent field method is well established as a means of performing dose calculations in rectangular and irregular fields. There is, however, no consensus on the equivalent diameter (D) of elliptical fields, despite their common applications in
