GE Healthcare

Removal of the Bucky

Pull the Bucky from both sides and pull it away from the C-Arm. Use both

hands when removing the Bucky.

NOTE!

See more information of accessories in Special Exposures section.

Exposures with the Magnification tunnel

The magnification tunnel produces a magnified image of the breast. This

is done by having a certain distance between the object and the film.

Magnification factors 1.6x, 1.8x and 2.0x are possible with the MultiChoice

magnification tunnel.

Insertion and removal of the face shield

The face shield is used to keep the patient’s face or ear lobes out of the X-

ray beam during exposure.

Insertion

Install or remove the face shield with a single horizontal movement along

the grooves (left image below). Accidental pinching of the patient during

the auto release of the compression paddle or some other situation is

prevented as the face shield moves upwards from the face shield holder

and away from the patient (right image below). If the face shield has come

off in such, or some other situation, insert it diagonally back to the holder.

Fig 3.4.
