Method and apparatus for obtaining stereotactic mammographic guided needle breast biopsies |
摘要 |
An add-on biopsy apparatus attached to a conventional mammography apparatus permits stereotactic imaging of a breast held in a mammographic position using an image receiver having a plane positioned perpendicular to the X-ray source. The perpendicularly positioned image plane allows the use of conventional moving scatter reducing grids to improve image contrast and quality of a stereotactic image made with an add-on biopsy apparatus. The biopsy apparatus also includes a control system for position a digital image receiver to compensate for image shifting during stereotactic imaging.
