Title:
HARD TISSUE SURFACE GEOMETRY DETERMINATION
Document Type and Number:
WIPO Patent Application WO2004065893
Kind Code:
A3
Abstract:
Apparatus for measuring a surface geometry of hard tissue covered by a layer of soft tissue, including a plurality of elements each having a tip adapted to penetrate said soft tissue and not substantially penetrate said hard tissue; a frame supporting movement of said elements, each along a path, such that a plurality of said tips, when positioned along the paths, define a surface; and at least one position sensor which generates a signal indicative of a tip position of at least one of said elements.
