摘要： A system and method for recording in real-time the duration, position, and energy of ion beams as delivered by a proton or heavy ion cancer treatment system for the purpose of calibrating the radiological system and verifying the treatment plans for various lesions. The energy of the ion beam is calculated from the beam ion depth penetration through a phantom as recorded on a two-dimensional scintillator surface which is viewed by a sensitive visible-light camera mounted in a darkened enclosure. The energy of the beam is degraded by a multi-step dual-slope chevron wedge phantom which creates, at a minimum, two bright spots in the camera's field of view. The distance between the centers of these two spots along with the dimensions and density of the multi-step dual-slope chevron wedge are used to calculate the Bragg Peak penetration depth of the ion beam.

摘要： An illuminator for measurement of curved specular surfaces is provided comprising a hemispherical support structure containing single or multiple polygonal groups of directional light sources, whose beams converge at a point underneath the hemisphere containing the area to be inspected. The lights reflect from the curved surfaces vertically through an aperture in the top of the hemisphere to one or more cameras that are part of a machine vision system. In one form of the embodiment, two octagonal groups of LEDs (Light Emitting Diodes) mounted at different elevations on the hemisphere are used. The shapes and patterns of the reflected points of light serve as fiducials for measurement of the positions, radii, surface quality and relative heights of the curved surfaces.
