Truly low-cost, low-power ultrasonic imaging probes that power from a smartphone over a USB 2.0 cable require optimization of every aspect of the imaging process
How much of the processing required can be done in software?
Can GPUs be used?
How can power draw be minimized?
Current-generation B-mode probes can be used with smartphones
½ Watt required from USB 2.0 port
FDA-approved system available commercially
Next-generation linear array probes will require additional optimization
