Time-of-flight PET

Seminars in Nuclear Medicine, 1998
Time-of-Flight (TOF) positron emission tomographs (PET) were developed during the 1980s and early 1990s. Initial investigations into the potential improvements in signal-to-noise ratios if TOF information was utilized were published in 1980. By 1982, two groups (Washington University and Commissariat á l'Energie Atomique-Laboratorie d'Electronique et ...

Time-of-flight neutron interferometry

Physical Review A, 1992
In the experiment described in this paper, a chopper serves as a source of neutron intensity pulses which pass through a perfect Si-crystal neutron interferometer (NI), where they are split coherently into two parts that recombine and interfere. As the occupation number of a single pulse is much smaller than unity, the results very clearly demonstrate ...
