Experimental determination of the weighting factor for the energy window subtraction–based downscatter correction for I-123 in brain SPECT studies
Correction for downscatter in I-123 SPECT can be performed by the subtraction of a secondary energy window from the main window, as in the triple-energy window method. This is potentially noise sensitive. For studies with limited amount of counts (e.g. dynamic studies), a broad subtraction window wi...
