Purpose: In defining the biological effects ofthe 10B (n,α)7 Li neutron capturereaction, we have proposeda deterministic parsing model (ISHIYAMA-IMAHORI model) to determine the Compound Biological Effectiveness (CBE) factor in Borono-Phenyl-Alanine (BPA)-mediated Boron Neutron Capture Therapy (BNCT). In present paper, we the case of application to actual patient data, which is founded on this model for tissuesandtumor. Method: To determine the CBE factor, we demonstrate a specific method of howthe application of derived the following new calculation formula founded onthe deterministic parsing model with three constants, CBE0, F, n and the eigen value Nth/Nmax.
