Charged particle state determination apparatus and method of use thereof
First Claim
1. A method for determining a charged particle beam state, comprising the steps of:
- extracting positively charged particles from a synchrotron;
transporting the positively charged particles from said synchrotron through a nozzle and at least into a patient;
imaging first photons to form a first signal, the first photons resultant from the positively charged particles transmitting through a first light emitting element on a first sheet;
imaging second photons to form a second signal, the second photons emitted from a second light emitting element upon the positively charged particles traversing through the second light emitting element on a second sheet, said second sheet parallel to said first sheet and not intersecting said first sheet;
determining a first vector of the positively charged particle beam path using the first signal and the second signal.

Abstract
The invention comprises a system for determining the state of a charged particle beam, such as beam position, intensity, and/or energy. For example, the charged particle beam state is determined at or about a patient undergoing charged particle cancer therapy using one or more film layers designed to emit photons upon passage of a charged particle beam, which yields information on position and/or intensity of the charged particle beam. The emitted photons are used to calculate position of the treatment beam in imaging and/or during tumor treatment. Optionally and preferably, updating a tomography map uses the same hardware with the same alignment used for cancer therapy at proximately the same time.
