Lokalisierungsmechanismus für NMR-kompatible Biopsievorrichtung

摘要

A localization mechanism, or fixture (16) is used in conjunction with a breast coil (34) for breast compression and for guiding a core biopsy instrument (14) during prone stereotactic biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines (12). The localization fixture (16) includes a fiducial marker (140) and three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument (14) with detachable probe/thumb wheel probe to the biopsy site of suspicious tissues or lesions.
