Why Are Ultrasound Machines So Expensive?
The cost of components is often not a big part of the cost of producing an imaging device like this.  Building hardware and software in a regulated market where human safety is involved requires levels of validation, verification, process control, risk analysis and documentation that can easily dwarf component cost at the sort of run sizes we are taking about.This isn't the only thing going on, but it is naive at best to think of the price of these units as a parts list.
