(a) PET singles event rate as the EPRI RF pulsing is turned on and off. Horizontal axis represents singles event time-stamp recorded in the MVT board. (b) A typical scintillation event consisting of 8 MVT samples (blue circles) and the signal waveforms estimated from them by using a simple piecewise linear interpolation-based method (dashed-line curve) and a bi-exponential fitting function (solid-line curve). (c) The waveform of an exemplary spurious RF event picked up by PET data acquisition. (d) Histogram of the falling time measured from the data acquired during EPRI RF pulsing. (e) Singles event rate after applying the RF rejection. (f) Pulse-height histograms for a detector pixel before and after applying the RF rejection.
