tend to have edges that are too large (8). In this article, we present an edge detection method for ejection fraction calculation that is based on edge parameter values that vary as a function of anatomic location. The method is clinically efficacious because: (a) computation time is short, (b) interobserver and intraobserver variabilities are low and (c)(More)
UNLABELLED We present a myocardial edge detection technique that was developed for fast, reproducible measurements of left ventricular ejection fraction in the clinical setting. METHODS This myocardial edge detection method compares three edge parameters--count amplitude and first and second count derivatives--in three consecutive locations along a radius(More)
