As the semiconductor technology scales down to 45nm and below, process variations have a profound effect on SRAM cells and an urgent need is to develop fast statistical tools which can accurately estimate the extremely small failure probability of SRAM cells. In this paper, we adopt the Importance Sampling (IS) based information theory inspired <i>Minimum(More)
BACKGROUND The evolution of T1ρ and of other endogenous contrast methods (T2, T1) in the first month after reperfused myocardial infarction (MI) is uncertain. We conducted a study of reperfused MI in pigs to serially monitor T1ρ, T2 and T1 relaxation, scar size and transmurality at 1 and 4 weeks post-MI. METHODS Ten Yorkshire swine underwent 90 min of(More)
BACKGROUND Premature ventricular complexes (PVCs) are prevalent in the general population and are sometimes associated with reduced ventricular function. Current echocardiographic and cardiovascular magnetic resonance imaging techniques do not adequately address the effect of PVCs on left ventricular function. METHODS AND RESULTS Fifteen subjects with a(More)
PURPOSE To develop a robust T1ρ magnetic resonance imaging (MRI) sequence for assessment of myocardial disease in humans. MATERIALS AND METHODS We developed a breath-held T1ρ mapping method using a single-shot, T1ρ-prepared balanced steady-state free-precession (bSSFP) sequence. The magnetization trajectory was simulated to identify sources of T1ρ error.(More)
