Abstract
A stereotactic auxiliary attachment for a tomography apparatus for conducting a tomogram-guided biopsy of a female breast has two compression plates arranged to be movable toward one another for fixing the breast therebetween, with through-holes arranged in the compression plates enabling a guided access of a biopsy needle to the breast through the compression plates. The through-holes in at least one of the compression plates are arranged obliquely relative to a surface normal of a compressing surface of that compression plate thereby permitting access to all regions of the breast tissue.
Claims5
A stereotactic auxiliary attachment for a tomography apparatus for conducting a tomogram-guided biopsy of a female breast, said attachment comprising:
- first and second compression plates adapted for receiving a female breast therebetween;
- means for moving said compression plates toward and away from each other for fixing a position of a breast therebetween;
- each compression plate having a plurality of through-holes therein arranged to provide a plurality of substantially arbitrary access paths, each hole adapted to receive a biopsy needle therethrough for providing a guided access of said biopsy needle into a breast;
- between said compression plates;
- and
- each compression plate having a pressing surface and said through-holes in at least one of said compression plates being oriented obliquely, relative to a surface normal, toward a chest wall of a subject of said compressing surface and forming means for accessing a site in a breast adjacent a chest wall.
