title: A simple device to assist in needle positioning procedures.
abstract: 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.
