Figure 9.5 shows a typical comparisonof therapeutic ( 10 B) dose profiles in the two setups. Itis clear that the new setup gives a better dosecoverage of the whole organ than the old one.Dose (arb. units)21The collaboration initiated in 2006Study of BNCT with INFN Pavia continued inapplied to lung 2007 in the framework of thetumoursBNCT lung project coordinatedby Pavia (supported by theMinistry for Higher Education and Research andINFN). The aim is to study the possibility of applyingBNCT in the treatment of diffuse lung tumours.0010 2030Depth into phantom along the central axis (arb. units)To test whether it was possible to uniformly irradiate the whole lung by using external neutron beams,Monte Carlo calculations were performed to evaluate the thermal neutron flux distribution in a model of thehuman thorax. The MCNP code and the anthropomorphic phantom ADAM [9.4, 9.5], in which the differentorgans are represented schematically using analytical volumes, were used. The MCNP capability forrepeated structures was implemented to voxelize ADAM’s thorax and the organs contained, obtaining amesh of voxels of 1 cm 3 .The thermal neutron flux and the dose distribution were calculated along chosen axes in the phantom’sthorax. With two opposite mono-energetic neutronbeams of 1 keV, the thermal neutron flux distributiondosimetry at the ENEA Radiation Protection Institute: was substantially homogeneous throughout the lunga review, ENEA Report RT/AMB/94/34 (1994) andpresented at the 4 th Conference on RadiationProtection Dosimetry (Orlando1994)151
