| Abstract |
An ASIC frontend has been developed for multianode photomultiplier based nuclear imaging devices. The chip architecture has been designed to improve resolution in future PET systems. Analog computation elements are isolated from photomultiplier by means of a preamplifier stage. This allows to individually adjust gain in every output and increase resolution in gamma event position calculation due to a reduction in parasitic capacitances. The ASIC also includes a measurement of the depth of interaction of the gamma event based on the width of the light distribution *. This feature aims to reduce parallax error and increase spatial resolution of the PET system. |
