Abstract

Controlled deflection of light cones from excited crystal pins has been realized in a positron emission tomography (PET) block detector that allows the enhancement of spatial resolution. The new light sharing module consists of special double prism units optically coupled to a continuous light guide. Slope angle in the prism units can be optimized for each pin in the array. We present well correlating results of light distribution measurements and simulations of single crystal pins with double prisms with different slope angles. First test results of spatial resolution improvement with optimized pixels of a block detector are also presented.
