Patent ID: 8471210

Claim:
An imaging method, comprising: collecting detector output data at an input count rate from a radiation detector that is positioned to view a subject provided with a radio-active tracer; and resolving by a processor individual signals in the detector output data to generate image signals at a throughput count rate, resolving the individual signals comprising: determining a signal form of said signals present in said detector output data, making parameter estimates of one or more parameters of said signals, wherein said one or more parameters comprise at least one signal temporal position, determining energy of each of said signals from at least said signal form and said parameter estimates, and maintaining the input count rate at or below a threshold input count rate, wherein the throughput count rate decreases for an input count rate value that is above the threshold input count rate, and wherein the throughput count rate decreases as an input count rate value that is below the threshold input count rate decreases.
