Abstract

2D ultrasound (2DUS) enables rapid assessment in a variety of clinical settings, but diagnostic accuracy depends on operator skill. Described previously in the literature, low-cost 2DUS-to-3DUS augmentation pairs orientation sensors with 2DUS probes, yielding anatomically oriented 3D volumetric images. We hypothesized that expert interpretation of 3DUS volumes would be more accurate than expert interpretation of 2DUS cine-loops, and that novice acquisition and expert interpretation of 3DUS volumes would be faster than novice acquisition and expert interpretation of 2DUS cine-loops.
