Claim 4:
5. The method of claim 4, further comprising the steps of:
said step of detecting further comprising the step of passing the passing the positively charged particles through a first time of flight detector element and at least into a second time of flight detector element;
receiving, into a beam state determination system, (1) a first signal related to an initial time of passage of the positively charged particles through said first time of flight detector and (2) a second signal related to an arrival time of the positively charged particles to said second time of flight detector element;
in a step of imaging the patient:
calculating a residual velocity of the positively charged particle after passing through the patient;
determining a velocity of the positively charged particle using a distance between the first time of flight detector element and the second time of flight detector element; and
determining an energy of the positively charged particle using the first signal, the arrival time, and a pathlength of the positively charged particles between the first time of flight detector and the second time of flight detector.
