Data Acquisition Aspects of Super-PETT

Incorporation of differential time-of-flight (TOF) information in positron emission tomography offers significant performance improvement at the cost of increasing the quantity of data to be processed. A tomographic unit utilizing TOF data, called Super-PETT, is currently nearing the final stage of construction. Design and implementation aspects of the data acquisition system are described with an emphasis on instrument operation in an on-line preprocessing mode.
