Medio-Lateral Projection
1
Select the required film size, load the film into the cassette and place
the cassette into the cassette holder.
2
Rotate the C-Arm to the lateral position (90º) by pressing pre-
programmed LAT-keys. If automatic ParkBack is disabled, drive the
tube head to the back to get more work space and better access to
the patient.
3
Adjust the cassette holder to a suitable height with the vertical drive
controls. The cassette holder should reach the height of the patient’s
axilla. The medial portion of the breast needs to be in contact with
the image receptor. Ask the patient to hold the hand grip and to lean
towards the unit.
4
Place the breast on the cassette holder so that the breast totally
covers at least one of the AutoPoint AEC detectors. This can be
achieved by gently pulling the breast away from the chest wall.
5
Check that the breast covers the detector. Manually select the most
appropriate AEC detector or use the AutoPoint feature.
6
Apply compression using the foot pedal or the manual controls.
Make sure that the patient’s nipple is in profile and no skin folds are
present. If the tube head is back, drive it forward.
7
Check that the Ready light is on. Make the exposure by pressing the
exposure button and keep it pressed until the radiation indicator light
turns off and the audible exposure indicator stops.
