Non-metallic ultrasound-detectable markers

Abstract

Markers (e.g., treatment site markers, biopsy site markers) are composed of a non-metallic material having a composition and/or other features or characteristics such that the markers will generate twinkling artifacts when imaged with ultrasound. In this way, the composition of the markers enables their detection and localization using ultrasound. The markers are generally composed of non-metallic materials that enhance the twinkling artifact.
