SOTA ultrasound devices are still very expensive, with e.g. a custom 3D probe with a few hundred piezo elements costing well over 10k. IF they want to use MEMS probe instead of piezo (which is implied by them saying that they will use a chirp), that's going to be even more expensive, considering the lack of manufacturing know-how. When sufficiently scaled, I wouldn't say it is an exorbitant price for large research hospitals, but I am a little skeptical of rolling these out as a health checkup "spa" service outside of areas with extreme wealth concentration (e.g., Silicon Valley? Sure. London? Yeah; Minneapolis? not so sure.)
