More Information
Summary:Provided is an acoustic coupler capable of achieving both low elastic modulus and high deformability required for ultrasound imaging. The acoustic coupler is disposed between a probe for transmitting ultrasound waves and a subject, the acoustic coupler comprising a hydrogel including a copolymer that contains water. The copolymer comprises a monofunctional monomer having one ethylenically unsaturated group and a polyfunctional monomer having two to six ethylenically unsaturated groups. The molar ratio of the monofunctional monomer to the polyfunctional monomer is more than 90 and less than or equal to 3500.
