At breast biopsy, use of a simple disk that fits into the hub of the needle can facilitate accurate placement of the needle with conventional lesion localization techniques. This disk forms a surface onto which the shadows of the localization crosshairs project so that the operator can advance the needle and maintain its alignment in the direction of the mammography beam by using the field light. The insert has been used successfully in more than 100 procedures.
在乳腺活检中，使用一个能适配针座的简单圆盘，可借助传统的病灶定位技术来促进针的精准放置。该圆盘形成一个表面，定位十字线的阴影投射在这个表面上，这样操作人员就能通过使用现场灯光推进针，并使其保持在乳腺X线摄影束的方向上。该插入物已在100多次操作中成功使用。
