Abstract :
A new concept is presented realizing controlled deflection of emerging light cone from excited crystal pins in a PET block detector. The new light sharing module consists of special double prism units optically coupled to a continuous light guide. Slope angle in the prism unit can be optimized for each pin in the array. We present results of simulations for a block detector consisting of an array with 21 × 21 pins and four 1.5" PMTs. First test results with a small 5 × 5 light deflector are also presented.
