Abstract
For calibration () for quantitative SPECT, a multiple energy emission source () is used for calibration. The planar sensitivities and/or uniformities are determined at different emission energies based on detections from the multiple energy emission source. For estimating () the activity concentration, sensitivities and/or uniformities based on measures () at different emission energies increase accuracy. The multiple energy emission source () may alternatively or additionally be used to calibrate () a dose calibrator ().
