Abstract

The treatment planning of BNCT (Boron Neutron Capture Therapy) differs from the conventional photon external radiation therapy. The patient positioning in the BNC-treatment horizontal static epithermal neutron beam is studied with the head model of a healthy volunteer. The anatomical reference points on the healthy volunteer's head were marked with cod-liver oil capsules and the intracranial volume was MRI imaged after the requirements of the 3D Monte Carlo BNCT_Rtp/rtt_MC program. BNC- treatment effects in the fictitious tumour and the surrounding healthy tissues were evaluated in the aspect of patient positioning. According to our calculations a 5 mm positioning error leads to 5% minimum tumour dose reduction in the planning target volume with the single Ø11 cm beam.
