ABSTRACT:
A fixture for shaping and compressing a pendant breast during tomographic mammography procedures. The breast extends pendantly downward into a fluid transmission medium having x-ray absorption characteristics substantially equal to those of human tissue. The breast is upwardly compressed and shaped into a cylindrical form by a thin membrane containing a body of pressurized water and affixed to an upwardly directed concave pan. Tomographic scans are accomplished by rotating an x-ray source and detector about a vertical axis passing through the breast and translating the source and detector vertically along the axis.
