Last replied to at February 20, 2016, 11:59 am I tried to pass ultrasound through an LDPE sheet into the human body.This is a part of my research. I used a coupling gel between LDPE and transducer and LDPE and human body. But all the ultrasound was reflected from the sheet itself,nothing was going into the body. Can anyone clarify why its happening.
