Infimal convolution‐based regularization for SPECT reconstruction
PURPOSE: Total variation (TV) regularization is efficient in suppressing noise, but is known to suffer from staircase artifacts. The goal of this work was to develop a regularization method using the infimal convolution of the first‐ and the second‐order derivatives to reduce or even prevent stairca...
