Open the CIPO recordAbstract From the Canadian patent
An improved transducer construction for a scintillation camera in which a light conducting element is equipped with a layer of moisture impervious material. A scintillation crystal is thereafter positioned in optical communication with the moisture impervious layer and the remaining surfaces of the scintillation crystal are encompassed by a moisture shield. Affixing the moisture impervious layer to the light conducting element prior to attachment of the scintillation crystal reduces the requirement for mechanical strength in the moisture impervious layer and thereby allows a layer of reduced thickness to be utilized. Preferably photodetectors are also positioned in optical communication …
