摘要：

The potato peeler perspective provides a way to identify redundant information in the SPECT data function. Its mathematical formulation in terms of "variable" sinograms demonstrates mathematically data redundancy in the SPECT data function even when the attenuation map is non-uniform. In this work, we extend the mathematical result to include the case when the activity distribution has a finite number of jump discontinuities.
