Research Project: Sub-100 ps Time Digitizer for High Throughput PET

Investigators: P. Denes, S. Derenzo, H. von der Lippe, E. Mandelli, W. Moses

Purpose: Demonstrate feasibility of doubling PET scanner throughput by using high-precision time-of-flight measurements to perform simultaneous calibration and detection.

Approach and Methods: PET scanner patient throughput could be doubled if it were possible to perform simultaneous calibration and measurement. This would be possible with LSO-based PET scanners by using time-of-flight to determine the origin of the detected photons (i.e. the radio-pharmaceutical in the patient or the external calibration source). To make this possible, a compact time digitizer with ~100 ps sensitivity must be developed. We will develop this digitizer in 0.25m or 0.18m CMOS technology, and demonstrate the feasibility of the approach with LSO detector modules.
