Liquid Electrodes Morph Into Flexible Wires for Neural Stimulation

Our nervous system is specialized to produce and conduct electrical currents, so it’s no surprise that gentle electric stimulation has healing powers. Neural stimulation—also known as neuromodulation, bioelectronic medicine, or electroceuticals—is currently used to treat pain, epilepsy, and migraines, and is being explored as a way to combat paralysis, inflammation, and even hair loss. Muscle stimulation can … Continue reading Liquid Electrodes Morph Into Flexible Wires for Neural Stimulation

Combining dual-tree complex wavelets and multiresolution in iterative CT reconstruction with application to metal artifact reduction

This paper investigates the benefits of data filtering via complex dual wavelet transform for metal artifact reduction (MAR). The advantage of using complex dual wavelet basis for MAR was studied on simulated ... Source: Biomedical Engineering Online

A new method for detecting the outer corneal contour in images from an ultra-fast Scheimpflug camera

The Corvis® ST tonometer is an innovative device which, by combining a classic non-contact tonometer with an ultra-fast Scheimpflug camera, provides a number of parameters allowing for the assessment of corneal b... Source: Biomedical Engineering Online
