The SNR of positron emission data with Gaussian and non-Gaussian
time-of-flight kernels, with application to prompt photon coincidence
Abstract
This paper analyses noise propagation in positron emission tomography
(PET). It presents a method to compute the effective signal-to-noise
ratio provided by the time-of-flight (TOF) measurement.
The proposed method can be used to compare TOF-PET systems with
different and possibly event-dependent TOF-kernels, as encountered when
prompt photons, such as Cherenkov photons are present, or when the
detector is composed of different scintillators.
