Fig. 1

Short axis views of ECG-gated patient SPECT data reconstructed with OSEM and TOSEM algorithms as displayed by Quantitative Gated SPECT 2012 program. It can be seen that the eighth bin in the OSEM-reconstructed image series has a lower activity level compared to other bins due to heart rate variability. This phenomenon is not present in the TOSEM-reconstructed image series
