    Abstract: Three semiconductor detectors (22) are installed at positions where incidence of radiation on a scintillation detector (21) is not blocked, at equal intervals centered on a central axis of the scintillation detector (21) and at equal angles with respect to a plane which is at a right angle to the central axis. An energy compensation factor is determined on the basis of an average pulse height value obtained from a second pulse height spectrum obtained by analog voltage pulses which are output from these semiconductor detectors (22), and energy characteristics of a high-range dose rate obtained by a direct-current voltage which is output from the scintillation detector (21) are compensated for.

    Abstract: An apparatus and method for in vivo and ex vivo control, detection and measurement of radiation in therapy, diagnostcs, and related applications accomplished through scintillating fiber detection. One example includes scintillating fibers placed along a delivery guide such as a catheter for measuring applied radiation levels during radiotherapy treatments, sensing locations of a radiation source, or providing feedback of sensed radiation. Another option is to place the fibers into a positioning device such as a balloon, or otherwise in the field of the radiation delivery. The scintillating fibers provide light output levels correlating to the levels of radiation striking the fibers and comparative measurement between fibers can be used for more extensive dose mapping. Adjustments to a radiation treatment may be made as needed based on actual and measured applied dosages as determined by the fiber detectors. Characteristics of a radiation source may also be measured using scintillating materials.

    Abstract: A fibrescope comprises a scintillator arranged to produce light of a first wavelength upon exposure to radiation; an optical system arranged to receive and direct light of the first wavelength emitted from the scintillator, the light being received at one end of the optical system, and wherein one or more elements of the optical system emits scintillation light of a second wavelength upon exposure to radiation; and an optical filter, disposed at the other end of the optical system, and arranged to transmit light of the first wavelength and block light of the second wavelength. The scintillator is chosen such that the light of the first wavelength is spectrally distinct from the light of the second wavelength.

    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.
