Background In patients with acute anterior myocardial infarction (MI), sometimes an “apical ballooning” contractile dysfunction pattern that exceeds factual myocardial injury is identified in the ventriculography and bedside echocardiography. The

Purpose The authors recently developed a preconditioned alternating projection algorithm (PAPA) for solving the penalized-likelihood SPECT reconstruction problem. The proposed algorithm can solve a wide variety of non-differentiable optimization mode

Background: Although morphological abnormalities of the heart appear to be remarkable, most patients with tako-tsubo cardiomyopathy (TTC) remain clinically stable. We investigate real time changes in the left ventricular (LV) and right ventricular (R

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-o
