The Nanox ARC cold-cathode, tomosynthesis 3D X-ray system is currently pending FDA clearance. If cleared, it would be the first device of its kind to offer cold-cathode X-ray tube technology and the ability to slice through the anatomy in images similar to CT scans to aid diagnosis. The new type of tube also could greatly reduce the size and weight of X-ray systems. The vendor sees this system as key to its larger plan to address health disparities and access to imaging world-wide. #Nanox

The University of Southern California was among the first imaging centers in the U.S. to install a 7T MRI. This high-end part of the MRI market is small and is mainly made up of academic research centers. The main MRI market is made of of 1.5T systems, but there is rising demand for 3T, which Signify research may eventually become the standard for MRI.

Top MRI trends include helium-free systems, compressed sensing and AI

Signify Research outlines several key technologies and trends in MRI to look for at the Radiological Society of North America 2022 meeting.
