Abstract
A pad for transmitting acoustical waves between an ultrasound probe and a target surface. The pad includes a first layer having a first porous portion which defines first layer pores therethrough. The first layer pores have a first layer pore dimension. The pad further includes a second layer having a first porous portion which defines second layer pores therethrough. The second layer pores have a second layer pore dimension. The second layer is attached to the first layer to define a space therebetween. The first porous portion of the first layer overlies the first porous portion of said second layer. An ultrasound couplant is disposed in the space defined between the first and second layers. The ultrasound couplant has a molecule size that is less than or substantially equal to the first layer pore dimension and less than or substantially equal to the second layer pore dimension.
