Abstract
The invention provides a surface marker for use in ultrasonography. The marker comprises a material which attenuates a portion of the ultrasound energy applied to an ultrasound field including the marker and tissue underlying the marker. When placed on the surface of the skin above a particular tissue structure and then imaged, the marker projects a shadow of reduced sonic energy into the underlying tissue structure. The shadow provides direct visual evidence that the tissue beneath the marker has been imaged. The shadow projected by the marker may also be used to locate the image of an area of particular clinical interest within the tissue structure, such as a tumor or cyst.
