摘要： In order to overcome or at least mitigate difficulties in compensating for movement of the target, for example a tumour during radiotherapy, a dosimetry apparatus and method embodying the present invention employ a dosimeter having at least one radiation detector and at least one magnetic position sensor located a predetermined distance apart. Radiation level readings from the radiation detector and position readings from the position sensor are monitored and correlated, conveniently according to time, to obtain the position of the radiation detector when a particular radiation level was detected.

摘要： A detector assembly for multi-modality PET/SPEC/CT scanners comprises a first layer for detecting low energy gamma radiation and X-rays and a second layer for detecting high energy gamma radiation. The first layer is generally transparent to high energy gamma radiation. The second layer may advantageously provide measurement of depth of interaction of the high energy radiation. The first layer is preferably in the form of a thin CsI(TI) scintillator, while the second layer includes a pair of LSO/GSO scintillators. The detector assembly includes a photodetector, preferably in the form avalanche photodiode to transform the light signals from the scintillators into electric signals. The detector assembly is advantageously incorporated in a multi-modality PET/SPECT/CT scanner allowing simultaneous transmission and emission imaging with the same detection geometry.
