Virtual steerable acousto-optic waveguides for non-invasive deep brain imaging and stimulation

We introduce a radical approach to use ultrasonic waves to confine and steer light deep (a few millimeters) into the tissue without having to insert a physical light guide. Ultrasonic pressure waves launched from outside can propagate in the brain tissue with minimal loss and change the density of medium locally and interact with light to define and steer the trajectory of light.
