<p>A scintillation detector comprising: an array of scintillation crystal elements (22); an array of detection elements (26); and a plurality of light guides (24) connecting each crystal element to multiple ones of the detection elements, so that a scintillation event in any one of the crystal elements gives rise to a signal being generated on a particular combination of the detection elements. This design allows a detection array with a relatively small number of elements, e.g. 61, to be used in conjunction with a scintillation array with a much larger number of elements, e.g. 400. High spatial resolution is thus achievable. Moreover, a high speed digital processor (28) can be used to provide rapid read out of the address of the crystal element where any scintillation event occurred.</p> |
