We are presenting a novel design of a high performance brain dedicated PET scanner which focuses on optimizing imaging performance in the whole brain, as well as in head and neck, through simultaneous high resolution and high sensitivity. This is realized using a sensitivity-optimized scanner design composed of an elliptical cylinder that follows the shape of the human head, together with added front and back panels for increased coverage.

20-ps resolution Clock Distribution Network for a fast-timing single photon detector
/ Egidos, N (CERN) ; Ballabriga, R (CERN) ; Bandi, F (Seville U.) ; Campbell, M (CERN) ; Gascon, D (ICC, Barcelona U.) ; Gomez, S (ICC, Barcelona U.) ; Fernandez-Tenllado, J M (CERN) ; Llopart, X (CERN) ; Manera, R (ICC, Barcelona U.) ; Mauricio, J (ICC, Barcelona U.) et al.
The time resolution of active pixel sensors whose timestamp mechanism is based on Time-to-Digital Converters is critically linked to the accuracy in the distribution of the master clock signal that latches the timestamp values across the detector. The Clock Distribution Network that delivers the master clock signal must compensate process-voltage-temperature variations to reduce static time errors (skew), and minimize the power supply bounce to prevent dynamic time errors (jitter).
