CHICAGO, Nov. 29—GE Healthcare’s Science and Technology Pavilion was well worth the trek this week at the 93rd annual meeting of the Radiological Society of North America (RSNA). Among many other visionary products, the company showcased Collaboration Wall, a multi-touch user technology developed in partnership with Perspective Pixel. Similar to an iPhone, the 8 x 3 foot screen improves on the traditional medical conference room by allowing multiple users to interact with images, videos and data.
