Computer engineers at Washington University created a prototype that took ultrasound imaging to a new level of mobility and connectivity — they connected an ultrasound probe to a smart phone.

Now Mobisante, a startup awaiting clearance from the U.S. Food and Drug Administration,  hopes to begin selling the device next year.

Such a device would be useful for emergency responders, who could scan an injured person to detect internal bleeding or other trauma, and then immediately send an image to the hospital so physicians could be better prepared for the patient’s arrival. Or a nurse practitioner visiting a pregnant woman’s home could ask a specialist stationed elsewhere to weigh in on anomalies in the scan.
