title: [Quality assurance in stereotactic punch biopsy using a phantom].
abstract: Lesions of the breast, which were only defined by mammography, can histologically be clarified by stereotaxic high-speed core cut biopsy. In a quality control procedure we have proved the accuracy of the localization unit and the biopsy equipment. A new acrylic-glass phantom allows visual detection of localization faults in the z-axis (direction of biopsy) for the first time with minimal coefficients of variation in all three axes. Quality control in the stereotaxic biopsy of breast lesions is absolutely essential for the practical use of this method.
