Recent Advances and Future Advances in Time-of-Flight PET.
Simple theory predicts that the statistical noise variance in PET can be reduced by an order of magnitude by using time-of-flight (TOF) information. This reduction can be obtained by improving the coincidence timing resolution, and so would be achievable in clinical, whole body studies using with PET systems that differ little from existing cameras. The potential impact of this development is l...
متن کاملRecent developments in time-of-flight PET.
While the first time-of-flight (TOF)-positron emission tomography (PET) systems were already built in the early 1980s, limited clinical studies were acquired on these scanners. PET was still a research tool, and the available TOF-PET systems were experimental. Due to a combination of low stopping power and limited spatial resolution (caused by limited light output of the scintillators), these s...
متن کاملTime of Flight in PET Revisited
PET scanners based on LSO have the potential for significantly better coincidence timing resolution than the 6 ns FWHM typically achieved with BGO. This study analyzes the performance enhancements made possible by improved timing as a function of the coincidence time resolution. If 500 ps FWHM coincidence timing resolution can be achieved in a complete PET camera, the following four benefits ca...
متن کاملAdvances in gaseous time-of-flight detectors
Timing Resistive Plate Chambers (RPCs) are planar gaseous detectors made with a combination of metallic and resistive electrodes, delivering time resolutions around 50 ps σ and efficiency up to 99% for MIPs. In this work we describe the development and test of an electrically shielded timing RPC array for crosstalk-free time measurements in high granularity time-of-fight (TOF) systems, as the I...
