A spot compression and magnification device for use with mammographic units to aid in the spot compression of a female patient's breast to obtain a high degree of focal breast compression and a high quality x-ray image of a suspicious mass within the breast. The device is positionable on the image platform of a conventional mammographic unit and has a base including an open bottom and an upstanding pedestal opening into the base, the pedestal having a flat top surface so that an air gap is provided between the top surface of the pedestal and the surface of the imaging platform. The device is constructed from a synthetic plastic material of sufficient rigidity and having low x-ray absorptivity. The base has excluded material in the form of an opening to increase the flexibility of the device to permit increased depression of the top of the pedestal facing the patient. The pedestal has a substantially truncated conical form while the base has a substantially rectangular cross sectional configuration.

The device has a base including an open bottom and an upstanding pedestal opening into the base, the pedestal having a flat top surface so that an air gap is provided between the top surface of the pedestal and the surface of the imaging platform or cassette cover of a conventional mammographic unit. The pedestal has a sustantially truncated conical form while the base has a substantially truncated pyramid configuration. Clamping handles are resiliently attached to portions of the base to permit the handles to be pulled away from the base and be urged into clampimg engagement with a small size cassette cover using a first set of tongues on the handles acting in conjunction with the bottom edge of the base or into clamping engagement with a larger size cassette cover using a second set of tongues on the handle acting in conjunction with a bottom surface of the first tongues.
