Abstract
The invention relates to a method and apparatus for charged particle tomographic imaging using a tomography system. The tomography imaging system is optionally simultaneously operational with a charged particle cancer therapy system using common elements, allows tomographic imaging with rotation of the patient, is operational on a patient in an upright, semi-upright, and/or horizontal position, is simultaneously operational with X-ray imaging, and/or allows use of adaptive charged particle cancer therapy. The common tomography and cancer therapy apparatus elements are operational in a multi-axis and/or multi-field raster beam mode.
