Claim 6:
7. A cover for an ultrasound scanning assembly, wherein the cover exerts compressive force on a patient during use, the cover comprising:
an outer frame; and
a film material extending across the outer frame,
wherein the film material comprises:
a substrate layer having a first surface and a second surface,
wherein the substrate layer comprises a solid, non-porous polyurethane film material;
a first hydrophilic coating layer applied to the first surface of the substrate layer; and
a second hydrophilic coating layer applied to the second surface of the substrate layer,
wherein each of the first hydrophilic coating layer and the second hydrophilic coating layer have a thickness ranging from 2 to 5 microns,
wherein the substrate layer is separate and distinct from the first hydrophilic coating layer and the second hydrophilic coating layer, and
wherein each of the first hydrophilic coating layer and the second hydrophilic coating layer is configured to be activated using only water or saline to provide a requisite acoustic coupling interface between the ultrasound scanning assembly and the patient.
