    Abstract: The invention pertains to a measurement device comprising two sensors for measuring radiation doses. The sensors are, for example, optical waveguides aligned along a straight line. One of the optical waveguides covers a longer section along the line than the other waveguide; in particular, the difference is at least 20 mm. Measurement using the measurement device is done as follows: the radiation dose along the line of radiation down to the expected penetration depth is measured using the wider sensor; the narrower sensor is used to determine the radiation dose in a volume element within the radiation path. A quotient is formed from the two measurements and used to calculate the radiation depth on the basis of reference values. The proposed device facilitates rapid and simple determination of a penetration depth of an ionising radiation, for example in tissue.

    Abstract: An apparatus and method are disclosed for detecting and locating the origin of a gamma ray in a medical diagnostic imaging system. At least one primary fiber, which is a scintillating optical fiber (21) is positioned to receive radiation from a gamma ray source. At least one secondary fiber intersects the primary fiber at a non-zero angle. Both fibers have a core surrounded by a cladding (22, 23), with the claddings of the two fibers in optical contact at an intersection point (24). Both the primary and secondary fibers are provided with means for detecting light propagated in the fibers. The interaction of radiation such as a gamma ray with the primary fiber will result in the propagation of light in both the primary and secondary fibers, thereby permitting the determination of the site of impact of the gamma ray in the detector, and possibly also enabling the determination of the path of incidence of the gamma ray.
