1. A method of developing a treatment plan for neutron capture therapy of a target organ containing a tumor, said method comprising:
- using a diagnostic cross-sectional scanner to scan the target organ to generate cross-sectional images of the organ;
generating a three-dimensional model of the organ from the cross-sectional images, said model including information about variations in internal composition of the organ in addition to said tumor; and
computing a three-dimensional array of expected radiation doses throughout the organ assuming a given arrangement of one or more neutron beams, said computing step using the three-dimensional model of the organ to compute said three-dimensional array of expected radiation doses.

Abstract
A method for developing a treatment plan for neutron capture therapy of a target organ including the steps of using a diagnostic cross-sectional scanner to scan the target organ to generate cross-sectional images of the organ; generating a three-dimensional model of the organ from the cross-sectional images, the model including information about internal features of the organ; and using the three-dimensional model to compute expected radiation doses throughout the organ assuming a given arrangement of one or more neutron beams.

19. A method of developing a treatment plan for boron neutron capture therapy of a patient'"'"'s brain, said method comprising:
-
using a diagnostic cross-sectional scanner to scan the patient'"'"'s head to generate cross-sectional images of the head; generating a three-dimensional model of the head from the cross-sectional images, said model including information about variations in radiation transport properties inside the organ; computing a three-dimensional array of expected radiation doses throughout the head assuming a given arrangement of one or more neutron beams, said computing step using the three-dimensional model of the head to compute said three-dimensional array of expected radiation doses and said computing step using Monte Carlo simulation techniques to compute said three-dimensional array of expected radiation doses; selecting a cross-section of the patient'"'"'s head for which dose information is desired; computing isocontours for the selected cross-section from the computed three dimensional array of expected radiation doses; and displaying the computed isocontours over a CT image of the selected cross-section.
