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： A distribution type detector comprises scintillation fibers identical in length to each other, an optical delay fiber having a refractive index substantially identical to those of cores and claddings of the scintillation fibers, photosensitive elements, preamplifiers, constant fraction discriminators, a time-to-pulse height converter, an analog-to-digital converter, and a multichannel pulse-height analyzer. A position where a radiation falls on its corresponding scintillation fiber, is detected based on a difference between time intervals necessary for propagation of optical pulses produced in the corresponding scintillation fiber by the radiation. Thus, even if the length of each scintillation fiber is increased, position resolution can be kept high and a measuring circuit system can be simplified.
