SCINTILLATIONSKAMERA MED EN SIGNALKORRIGERINGSKRETS

摘要

An Anger-type scintillation camera having analog circuitry in the form of seven correction generators each associated with one of a central seven of an array of nineteen photomultiplier tubes to compensate for spatial non-linearities in the camera. Each correction generator is active for scintillations produced by gamma ray interactions near its associated photomultiplier tube and produces correction signals which are added to the coordinate signals of an Anger-type camera to produce corrected corrdinate signals which represent more accurately the true spatial coordinates of the gamma ray interaction.
