Abstract: 3D ultrasound reconstruction allows physicians to explore a region of interest (ROI) in 3D while leveraging the advantages of 2D ultrasound imaging: simple, low cost and non-ionizing. It may ...

Abstract: Compared to conventional 3D radar systems, 4D radar systems require higher angular resolution in both azimuth and elevation. Besides, sparse arrays offer several advantages, including ...

A research team led by NIMS has, for the first time, produced nanoscale images of two key features in an ultra-thin material: twist domains (areas where one atomic layer is slightly rotated relative ...
