A handheld ultrasound machine can be a lifesaver in remote areas and disaster zones, but workers may not have a specialist available to read the images it produces. The MobiUS SP1 is the first mobile ultrasound device that can encrypt and e-mail images to an off-site physician via smartphone. Health-care workers can use the ultrasound wand to image organs and fetuses, and to check for internal bleeding. $7,500 and up (includes phone)
