ABSTRACT:
A device for measuring the absorption of radiation in a layer of a body, utilizing a radiator emitting a fanned radiation beam which passes through the body and which is measured by a number of adjacently arranged detectors. The radiator/detector system is rotated with respect to the body during the measurement. Integral measuring values of mutually intersecting sets of parallel strips are used for calculating the absorption. To this end, the device comprises means for sampling signals supplied by the detectors at different instants and/or means for effecting the sampling after different signal delay times.
