Zonare's newly enhanced z.one ultra, launched commercially this month and showcased at the European Congress of Radiology in Vienna, features a 19-inch diagonal screen built into a redesigned portable cart. The upgraded product, which can operate as a cart-based or hand-carried ultrasound system, features software that automatically adjusts the gain and brightness of images and traces spectral Doppler waveform. Glen McLaughlin, Ph.D., chief technology officer and vice president of engineering at Zonare, demonstrates some of the new system's highlights.
