Project description

Neurostimulation is a powerful tool in medicine and neuroscience. It can be used to restore the vision of patients with damaged photoreceptors by stimulating surviving retinal cells.The main technique currently being used to stimulate the retina is ultrasound-based stimulation along with phased array beamforming. That technique is successful to a certain extent, but based on our simulation results, it requires a significantly larger number of transducers for the same stimulation accuracy by use of signal processing to align energy fields. By exploring a new way to approach the problem, we hope to improve upon the existing technique and therefore make ultrasonic retinal stimulation more effective.
