Abstract
The concepts used at the Finnish BNCT facility for the
patient dose quality assurance are introduced here. Dose
planning images are obtained using a MR scanner with MRI
sensitive markers. The dose distribution is computed with
BNCT_Rtpe. The program and the beam (DORT) model used
have been verified with measurements and validated with
MCNP calculations in phantoms. Dosimetric intercomparison
has been done between FiR 1 and BMRR BNCT beams. The FiR
1 beam has been characterised also by visiting teams.
Before every patient irradiation the relationship between
beam monitor pulse rate and neutron fluence rate in the
beam is checked by activation measurements. Cross-hair
lasers used in the patient positioning are checked for
spatial drift prior to each treatment. Kinetic models
used to estimate the time-behaviour of blood boron
concentration have been verified using independent
patient sample data to assess and verify the performance
of the applications. Quality control guides have been
developed for each step in the patient irradiation.
