ONLINE COVER Imaging Contractions. Monitoring uterine contractions is critical for reducing the risk of complications during labor, but current methods are invasive and lack spatial and temporal precision. Wu et al. have developed an imaging technique called electromyometrial imaging (EMMI) that can noninvasively generate high-resolution, three-dimensional (3D) electrical potential maps during uterine contractions. EMMI enabled visualization of the initiation and propagation of uterine contractions with high resolution in pregnant sheep. The image shows the uterine myometrial electrical signals in the background with a superimposed 3D reconstruction of the sheep uterus during contractions in the foreground (red and blue represent areas of greatest contraction).
