Abstract
A photomultiplier tube identifier is designed to identify a malfunctioning photomultiplier tube in a scintillation camera having an array of photomultiplier tubes. The photomultiplier tube identifier includes a photomultiplier tube for generating a photomultiplier tube signal. An amplifier/integrator generates an amplified/integrated signal from the photomultiplier tube signal. An analog to digital converter generates a digitized signal from the amplified/integrated signal. A series of pull up resistors generates a code signal identifying the photomultiplier tube. A bus buffer generates an encoded signal comprising the amplified/integrated signal followed by the code signal. A position computing device calculates the position of the photomultiplier tube. An image computer generates an image from a plurality of encoded signals. A display displays the image.
