On: Why Are Ultrasound Machines So Expensive?

Note the "to avoid aliasing" in the comment you are responding to.

You can also embrace aliasing if you are kind of crazy. Look for "compressed sensing" stuff. Although I'm unsure if this would be useful for anything on ultrasound systems.

Compressed sensing really isn't the same thing - and to do it properly you need random sampling. Still it's interesting stuff !

Not sure why downvotes. Parent is describing exactly the issues with undersampling that grandparent wanted to avoid.
