METHOD FOR DEAD TIME DETERMINATION IN A GAMMA CAMERA AND A SYSTEM FOR ACCOMPLISHING THE SAME

摘要

Disclosed herein is a method for estimating count loss in a gamma camera comprising injecting a synthetic pulse at a given rate into a data stream emanating from a photo detector; integrating the synthetic pulse into the data stream to form an integrated data stream; determining a number of synthetic pulses from the data stream that pass onto a final image; and determining the count loss from the Equation (2).
