    Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of photon counting of radiation.SOLUTION: A plurality of photo diodes has a bias voltage lower than a breakdown voltage applied thereto. A charge accumulation unit accumulates charges which are photo-electric converted by the photo diodes, and generates an electric signal having a signal voltage according to the amount of accumulated charges. A plurality of scintillators generates scintillation light when radiation is incident, and emits the generated scintillation light to the plurality of photo diodes. A data processing unit measures the amount of the scintillation light for each scintillator based on the electric signal.

    Abstract: The present invention provides a radiation detector (30, 100) which comprises a tube (102) and detector elements (106) distributed over the tube. Such an arrangement can be used to provide information on a radiation beam prior to interaction with a patient and after interaction with the patient. The detector is particularly compact and therefore suited to use with apparatus where space is restricted. By a particular arrangement of detectors and optical fibres (104, 108), the detector can provide data at all angles of rotation.

    Abstract: A detector for detecting ionising radiation comprises a scintillator (10) selected to emit light in response to incidence thereon of radiation to be detected, at least one detector (16) for detecting said emitted light, and at least one optical waveguide (12) for transmitting said emitted light to said detector (16).

    Abstract: A fiber optic scintillator includes (18), for example, a plurality of relatively low-density glass scintillating elements (20) for converting radiation into light and a plurality of relatively high-density glass radiation absorbing elements (40) interspersed among the plurality of scintillating elements (20). The high-density glass radiation absorbing elements (40) increase the x-ray stopping power of the scintillator and also produce electron showers which interact desirably in adjacent scintillating elements (20) to increase the luminance of the scintillator (18). The high-density glass radiation absorbing elements also absorb x-ray cross-talk from absorption of radiation in the scintillating elements (20) and desirably include optical absorbers for absorbing optical cross-talk, both of which improves the resolution of the scintillator (18). The plurality of scintillating elements (20) and high-density glass radiation absorbing elements (40) typically are fibers, and the high-density glass radiation absorbing elements (140) may define cladding around the scintillating low-density glass fibers.

    Abstract: Disclosed is a gamma camera in which separate detectors (112,114) are used to determine the position and energy of gamma radiation from a patient of interest. In a preferred mode, the camera comprises two adjacent, mutually perpendicular arrays (114,116) of parallel scintillating fibres positioned on the face of a scintillating crystal (112). Each of the fibres within the arrays conducts light to a photodetector (not shown) at one end, while an array of photodetectors monitors the total scintillated energy within the crystal (112). The arrays of fibres provide resolution in the x-y plane, while the sum of the energies detected in the fibres and crystal discriminate between transmitted and scattered radiation.
