Abstract

Contact radiotherapy uses small field sizes and very short SSDs to deliver low-energy X-rays very close to the position of a tumour. We present a Monte Carlo simulation of the Papillon contact radiotherapy machine, and in particular the backscatter factor, to investigate whether the factors given in current Codes of practice for kV dosimetry remain valid under these conditions.
