Abstract

The MARS medical reactor beam is analyzed for neutron capture therapy of deep neoplasm. Necessary conditions of the new approach are based on: a) precise delivery of the pharmaceutical with Boron or Gadolinium to a target and long-time confinement it, and b) using a high-energy & high fluence rate neutron beam, which provides neutron deep penetration. Results of the numerical experiment for administered dose delivery to a deep seated target for the modified MARS reactor beam are presented. It is shown, that new quality of results is quite achievable in acceptable time of an exposure.

Key words: NCT new concept, precise B/Gd delivery, high-energy neutron beam, removal block optimization, Gd-capture therapy, MARS reactor beam modification
