Functional ultrasound through the skull

We show new results for making functional ultrasound work through the skull.

On receive, we take the data measured by our real transducers in reality, and propagate the time-reversed version through the wave simulator, while recording at the virtual sensors. Previous work showed that tofu is desirable as a phantom material, both because it is fast to get and because it has similar physical properties (density, speed of sound) as soft tissue. Normal sterile syringes of different sizes were used and custom mounts for each one could be swapped in; this along with adjusting the actuator speed in our Arduino code allows us to vary the volumetric flow rate.
