Abstract
The invention relates to a method and apparatus for determining actual points along a positively charged particle beam path and/or vectors of the charged particle beam path, where the determined points and vectors aid tomographic construction of a three-dimensional image of a tumor and surrounding tissue. Further, the determined points and vectors of the positively charged particle beam are used in beam control safety, to modify a tumor treatment plan in real time, and/or in combination with co-gathered X-ray images to form a hybrid proton tomography—X-ray three-dimensional image. Preferably, common elements, such as an injector, accelerator, beam transport system, and/or patient positioning system are used for both tumor treatment and tumor imaging.
Claims10
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.
