Abstract:
MADPET-II is a small animal PET tomograph that features individual Lutetium Oxyorthosilicate (LSO) crystal readout from Avalanche PhotoDiodes (APDs). The detector signals are preamplified by 16-channel fully integrated ASICs which are placed as close as possible to the detector in order to avoid attenuation of the signal or unwanted stray capacitance. However, the power consumption of the preamplifier (30 mW per channel) can cause heat transfer and, consequently, gain drift to temperature sensit...     »
