Stereotactic mammography and needle biopsy table with ccd imaging system

摘要

The biopsy table (21) includes a platform (22), on which the patient lies in a prone position with the breasts passing through an aperture (37). An image receptor (36) is mounted on a C-arm (27) and can be rotated about an axis (29) able to be positioned between the patient`s breasts or against the underside of a breast. A tube-head (28) which delivers X-rays to the patient is positioned at the patient`s head end of the platform. The image receptor and a compression plate (53) positioned on the underside of the breast has a compression paddle (38) on the upper side of the breast, and are mounted on a compression arm (50) which also supports a needle guide (39) which is used to guide a biopsy needle to a lesion.
