Abstract
The need for a highly viscous couplant gel or water spray to form an acoustical couple for ultrasound testing is eliminated by employing an ultrasound probe module. A porous membrane and an ultrasound probe cooperate to define a chamber which contains a liquid acoustical couplant. When pressure is applied to the liquid acoustical couplant it passes through the porous membrane. The porous membrane and chamber are disposed such that ultrasound signals going to or away from the ultrasound probe pass through the liquid acoustical couplant and porous membrane.
