    摘要： Generally, a method or apparatus for tomographically imaging a sample, such as a tumor of a patient, using positively charged particles positions n two-dimensional detector arrays on n surfaces of a scintillation material or scintillator, respectively. Resultant from energy transfer from the positively charged particles, secondary photons are emitted from the scintillation material and detected by the plurality of two-dimensional detector arrays, where each detector array images the scintillation material. Combining signals from the plurality of two-dimensional detector arrays, the path, position, energy, and/or state of the positively charged particle beam as a function of time and/or rotation of the patient relative to the positively charged particle beam is determined and used in tomographic reconstruction of an image of the sample or the tumor.

    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 using one or more imaging systems positionable about the tumor and treating the tumor using positively charged particles, such as: (1) using a rotatable gantry support to support and rotate a section of a positively charged particle beam transport line about a rotation axis and a tumor of a patient; (2) using a rotatable and optionally extendable secondary support to support, circumferentially position, and laterally position a primary and optional secondary imaging system about the tumor; (3) image the tumor using the primary and optional secondary imaging system as a function of rotation and/or translation of the secondary support; and (4) treat, optionally concurrently with imaging, the tumor using the positively charged particles as a function of circumferential position of the section of the charged particle beam about the tumor.

    摘要： The invention comprises a method and apparatus for treating a tumor with protons using multiple beamline positions not having an isocenter, including the steps of: (1) delivering the protons from a synchrotron along a redirectable beam transport path to yield a plurality of incident vectors, each of the plurality of incident vectors directed toward the treatment room and (2) redirecting the protons traveling along each of the plurality of incident vectors, with an output nozzle, to the tumor, where a first vector, of the plurality of incident vectors, comprises a first direction intersecting the tumor and where a second vector, of the plurality of incident vectors, comprises a second direction passing by the tumor without entering the tumor. The step of redirecting directs the protons traveling along the first and second incident vectors, respectively, to a first and second path intersecting a front and the back of the tumor.

    摘要： A Faraday cup structure for use with a processing tool. The cup structure has a conductive strike plate coupled to a circuit for monitoring ions striking the strike plate to obtain an indication of the ion beam current. The electrically conductive strike plate is fronted by a mask for dividing an ion beam intercepting cross section into regions or segments. The mask including walls extending to the strike plate for impeding ions reaching the sensor and particles dislodged from the sensor from entering into the evacuated region of the processing tool.
