I don't need to transport that patient to another area of the hospital for additional imaging and exposure to additional staff and potentially patients along the way, the fact that I can bring a handheld ultrasound system that plugs into a phone into a room, do the exam I need, get the information I need, walk out and disinfect a phone and a probe — compared to wheeling in a cart with three different probes on it, doing that same exam, getting that same information... it's really night and day.
