This was my initial reaction also, but then realized the use case probably isn't always on continuous use.
An expecting parent is very excited by seeing the ultrasound of their unborn child. Maybe they wear a patch for a few hours to get more imaging, but I don't think they're going to do 24/7 for months at the risk of harming the baby.
