Title: SCREENING METHOD AND APPARATUS
Abstract:
A screening method and apparatus, the method comprising irradiating a subject for screening with excitation radiation, collecting detector output data from a radiation detector located near the subject, and resolving individual signals in the detector output data by (i) determining a signal form of signals present in the data, (ii) making parameter estimates of one or more parameters of the signals, wherein the one or more parameters comprise at least a signal temporal position, and (iii) determining the energy of each of the signals from at least the signal form and the parameter estimates. The screening time is shorter, dwell time is shorter, resolution is improved and/or throughput is increased.
