At RSNA 2011, Toshiba unveiled its Aplio 500 ultrasound system, which offers a unique 3-D fly-through imaging capability. The system takes the image dataset and processes it to create a cine loop fly-through of any hollow, fluid-filled blood vessel, duct or organ. The example in this video is of a blood vessel in the liver. The capability and image quality is similar to what is seen in a virtual colonoscopy created from CT datasets. The technology was highlighted in our editor's choice for most innovative new technologies at RSNA 2011. The future applications of this technology may include 3-D ultrasound navigation aids for vessels in the cath lab.
The most popular article in August was about advances in fractional flow reserve (FFR) technologies. The image shows Philips' new version of its iFR system that displays hemodynamic pressure drop points in an overlay on live angiographic images, matching up the iFR readings with corresponding lesions.
