Claim 0:
1. A method for imaging a tumor of a patient using positively charged particles longitudinally traversing a charged particle beam path, comprising the steps of:
sequentially transporting the positively charged particles from a synchrotron, through an exit nozzle, through a patient position, and to a scintillation material;
passing the positively charged particles through a material comprising a thickness of between ten and one hundred fifty micrometers thickness to reduce speed of the positively charged particles in an extraction process from said synchrotron;
providing a tomography imaging system, comprising:
a substrate sheet axially crossing the charged particle beam path prior to the patient position;
a coating material coating and contacting at least one side of said substrate sheet, transmission of the positively charged particles through said coating material resultant in locally emitted photons;
said scintillation material, positioned in the charged particle beam path after the patient position, emitting localized light upon receipt of the positively charged particles; and
tomographic reconstruction software;

said tomography imaging system determining a set of current beam positions at said substrate sheet using a detector to detect the locally emitted photons;
said tomography imaging system correlating the set of current beam positions at said substrate sheet with prior side patient interface positions of the positively charged particles and the patient;
generating a set of spatial images of the tumor using the light emitted from said scintillation material, as a function of relative rotation of the patient position.
