Convolution-subtraction technique to compensate for downscatter …
WebA convolution-subtraction method to remove the downscatter counts in the 70 keV projection data is proposed. First, the scatter response function (SRF) is derived by fitting the Monte Carlo simulated downscatter data acquired in the 70 keV window for Tc-99m point source located in a uniform elliptical cylinder.

With RMC, only a fraction of all projections of a SPECT study have to be MC simulated in a standard manner. The other projections can be estimated rapidly using the results of these standard MC calculations. For efficiency, approximations have to be made in RMC with … feuer nursing review cds
