Hi,
I previously posted an idea for making an fairly non-invasive device to measure pressure inside the body by measuring ultrasound cavitation, there is a new article out from January 20th ago that mentions using ultrasound cavitation:
relevant quotes from the article:
"At low frequencies, ultrasound produces tiny bubbles in a solution"
"The ultrasound exposure did not produce any adverse side effects"
Since this new article shows ultrasound microcavitation can exist in the body, the new question to ask is can the microcavitation effect be used to measure pressure in the body? The application of this could be to have a fairly non-invasive test for pressure in different parts of the body, that currently require invasive tests. Having real time continuous non-invasive pressure monitoring would probably be a good medical advance.
Here is the original message I posted on this from last year as well as a useful reply, and another comedic reply:

I think if you come up with a non-invasive method, people would be interested.
