Using a novel adaptive non-local-means denoising method permits radiation doses from any computed tomography scanner to be reduced by 50% without affecting diagnostic performance.
Using multiplexing and an LED array to code illumination angles in a commercial microscope achieves fast capture times, resolution beyond the diffraction limit, and a very large field of view.
Membrane-wrapped gold nanoparticles designed to have specific surface properties have been used to investigate and mimic complex viral processes.
