Number of beams, class solutions
standard number of beams is often applied to specific
treatment sites:
-
3,5 or 7 beams in prostate treatment
-
5,7,9 beams in head and neck treatment
class solution = ‘group average’ set of constraints, number of beams
and beam angles (for an ‘average’ patient!?)
consider class solutions a good starting point
look at differences between this patient and the group
(different shape, rotations, etc.)
