Abstract
Abstract An adjustable biopsy paddle for compressing tissue to be examined and assisting localization of a needle relative to a nonpalpable lesion, the paddle including a locator plate having a plurality of tissue access holes of generally uniform diameter and of generally uniform spacing in a first direction, typically the lateral direction. The paddle further includes a guide for permitting movement of the plate in the first direction for a distance of at least half the distance of the spacing, and a bracket for slidably supporting the plate.
