Devices and method are provided for ultrasound transmission without the need for external couplants, such as gels, which are typically used in conventional ultrasound procedures. In particular, ultrashields are provided for use with ultrasound probes, wherein the ultrashields have specialized layers to provide an uninterrupted pathway of acoustic conductance from the probe to the surface of the body throughout the procedure while introducing minimal to no attenuation of ultrasound wave transmission. In addition, combinations of ultrashields and probe covers are provided to provide additional features such as a microbial barrier.
