An ultrasound imaging marker has a marker body that is constructed of an ultrasound resonant material and that includes a resonant pocket. The marker body includes an interior surface and preferably an angled surface. The resonant pocket provides a feature that is easily visible to the ultrasound device. The interior surface is preferably coated with a metallic resonant layer such as alumina or gold. The angled surface bounds the interior surface and connects the interior surface with the perimeter lip. The ultrasound imaging marker is preferably used in conjunction with an insertion device for inserting the ultrasound imaging marker adjacent the location. |
