ABSTRACT

Modern Field Programmable Gate Arrays (FPGAs) are capable of performing complex discrete signal processing algorithms with clock rates of above 100MHz. This combined with FPGAs low expense, ease of use, and selected dedicated hardware make them an ideal technology for a data acquisition system for positron emission tomography (PET) scanner. Our laboratory is producing a high-resolution, small-animal PET scanner that utilizes FPGAs as the core of the front-end electronics. While this scanner uses an Altera ACEX1k and has limited complexity, we are also developing a new set of front-end electronics based on an Altera StratixII. This next generation scanner utilizes many of the features of modern FPGAs to add significant signal processing to produce higher resolution images. One such process we discuss is sub-clock rate pulse timing. We show that timing performed in the FPGA can achieve a resolution that is suitable for small-animal scanners, and will outperform the analog version given a low enough sampling period for the ADC
