Abstract
The invention comprises a method and apparatus for treating a tumor using positively charged particles having passed through an intervening object, comprising the steps of: predetermining an energy reduction of the positively charged particles resultant from the positively charged particles traversing the intervening object along a beam treatment path as a function of relative rotation of the patient and the beam treatment path; generating a radiation treatment plan adjusting energy of the positively charged particles delivered from the synchrotron to the intervening object to yield a desired beam treatment energy of the positively charged particles entering the tumor after compensating for the energy reduction; and optionally detecting a set of the positively charged particles after traversing the intervening object to yield a signal, where the signal is used with knowledge of energy of the positively charged particles exiting the synchrotron to pre-determine the energy reduction along the beam treatment path.
