摘要： The invention comprises a method and apparatus for using a multi-layer multi-color scintillation based detector element to image a tumor of a patient using a process of determining residual energies of positively charged particles after passing through the patient, the process comprising the steps of: (1) transmitting the positively charged particles at known energies through the patient and into a multi-layer detector element; (2) detecting first and second secondary photons, resultant from passage of the positively charged particles, respectively from a first layer of a first scintillation material and a second layer of a second scintillation material at two respective layer depths, where the first wavelength range differs from the second wavelength range; (4) determining residual energies of the positively charged particles, using output from the step of detecting; and (5) relating the residual energies to body densities to generate an image.

摘要： The invention comprises a method and apparatus for imaging a tumor of a patient with positively charged particles, comprising the steps of: (1) accelerating the positively charged particles to a relativistic energy using an accelerator; (2) transporting the positively charged particles from the accelerator, through a beam transport system, through an output nozzle of the beam transport system, and through the patient to yield a residual particle beam comprising a residual relativistic velocity; (3) determining the residual relativistic velocity using a first time of flight detector and a second time of flight detector separated by a separation distance; and (4) generating a positively charged particle computed tomography image using the residual relativistic velocity, where individual particles in the residual particle beam comprise a second mass of at least 1.02 times that of a first mass of the individual particles prior to the step of accelerating.
