Full-body, continuous wearable ultrasound will benefit health care and biomedical research. Seven key obstacles must first be overcome.

On a smartphone, a live feed cycled through views of heart valves fluttering, muscles flexing, the diaphragm’s rise and fall and the flow of blood through arteries.
