Ultra Cheap Ultrasound 

The technology in iPhones used to cost millions. Seriously?

No one has a patent on all CMUT technology.

this has been available commercially since around the time u made ur comment in the form of the butterfly iq handheld machines.... these are mainly just low quality phased array ultrasound machines that work okay for point of care ER/ICU assessment mainly for cardiology type stuff. they are wired handheld "pocket" devices, they cost ~$2,000 + 400$/yr or one time cost of ~$3,000. imo they are jack of all trades, master of none and have some growing pains but they seem to be on the right side of venture capital and the FDA in the US and EU.... ironically china has had better devices that are much cheaper and more functional with wifi, wireless charging, bluetooth, ect, and use higher strength crystals for much better resolution since around 2010 for like $1500-3000 but no one cared in the states. Now all the big name manufactures (GE, philliups, ect) have gone to these chinease mfg and licensed their same designs and are selling them in the US, possibly because of butterflyiq for like $4500, the most popular is the GE vscan air which does everything better except maybe quick cardiology point of care scans for PE/effusion/tamponade and maybe cardiac akinesia. im kind of wondering what will happen when these devices start to age since they likely get super hot while operating and will tend to break down. butterfuly cant even figure out how to make their cables last more than a year or two of light weekly use but hey their stock has apparently been doing well.

butterflyiq+ uses this garbage low power + resolution technology, $3,000. now you understand what "ultra cheap" means in western healthcare lol
