摘要： A radiation deep dose measuring apparatus. A corpuscular beam detector of scintillation fibers bundled together into a block is adjusted in position to have a width similar to the radiation range of corpuscular beams; a driving apparatus rotates the corpuscular beam detector and an image receiver together around a center corresponding to a radial axis of the beams; the image receiver captures the image of scintillation light emanating from the corpuscular beam detector; an image signal processing apparatus processes the image signal to produce the distribution of radiation doses as a function of depth; and a displaying apparatus displays the result. The radiation deep dose measuring apparatus allows rapid measurement of radiation doses in three-dimensional space.

摘要： In a depth dose measuring apparatus, a fluorescent substance block (1) bundling scintillation fibers of which radiation absorption characteristic is close to that of tissue, is disposed orthogonally to the incident direction of radiation (4-1). The fluorescence intensity distribution on the fiber end faces of the fluorescent substance block (1) is measured by an image measuring device (6). Therefore, the two-dimensional fluorescence intensity distribution in the incident direction of radiation and in another orthogonal direction, that is, the absorption dose distribution can be measured simultaneously by one irradiation. Moreover, if the fluorescent substance block (1) is composed by laminating plate-form scintillators, one-dimensional absorption dose distribution in the depth direction can be measured by one operation.

摘要： An apparatus for measuring absorption dose distribution may be used for radiotherapy, such as intensity modulated radiotherapy and radiosurgery. In the apparatus, measurement or evaluation of the distribution of the radiated dose within a phantom can be achieved accurately and in a relatively short length of time. The apparatus includes a phantom with a plastic plate scintillator having a thickness within the range of 0.15 to 1 mm and plastic blocks sandwiching the plastic scintillator, and an image analyzer. At least one of the plastic blocks is transparent and the image analyzer measures a pattern of intensity distribution of light emitted from the plastic scintillator when the phantom is irradiated.
