Abstract

Positron Emission Tomography (PET) is a medical imaging methodology based on the measurement of the concentrations of a positron-emitting radioisotope inside a three dimensional object. PET systems require hundreds of channels of high perfonnance detector readout electronics. The Phase I ASIC was developed in 1992 to reduce the cost, power consumption and complexity of PET systems and to improve reliability. The Phase I ASIC has been very successful and is a key component in thousands of commercial PET units currently in use.
