摘要:
An imaging method and apparatus, the method comprising collecting detector output data from a radiation detector positioned near a subject provided with a radio-active tracer, 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 acceptable subject to detector distance is reduced or increased, spatial resolution is improved, tracer dose or concentration is reduced, subject radiation exposure is reduced and/or scanning time is reduced.
