A biopsy chair should be used for the patient that provides good support
to the patient’s back and arms. An optional biopsy chair is available from
GE for use with Diamond.
WARNING!
Ensure that the pedals placed so that the patient cannot reach the
switches during positioning or imaging.
NOTE!
Make sure that C-Arm can rotate freely and that it is not obstructed in
such a way that it may strike an object causing the system to tilt. Also
ensure that the users does not position themselves between the C-Arm
and any obstruction, as injury could result. If necessary, use emergency
stop buttons or any button on the Diamond unit, except if it is on the
Control Panel.
Manual biopsy procedure
1 Make the patient comfortable in the sitting position.
2 Adjust the compression paddle to a suitable height using the foot
pedal or manual controls or with the vertical movement keys.
3 Place the breast on the cassette holder so that the breast totally
covers at least one AEC detector.
4 Turn the patient’s head to the side. Apply compression using the foot
pedal or manual controls.
Take care that the patient’s nipple is in profile and no skin folds are
present. Do not compress the breast quite as much as in a routine
examination, since it must remain compressed for some time until the X-
ray film is developed. However, the compression must be enough to
prevent the breast from moving. Too little compression allows the breast
to move and the biopsy will be inaccurate.
NOTE!
Make sure that the patient’s head is out of the light field.
5 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. Do not release the compression.
6 Develop the film. The holes in the compression paddle can be seen
on the image, and localization of the biopsy target can be made.
NOTE!
In case the patient moves in the middle of a procedure or compression
thickness is changed, in order to guarantee the accuracy of the biopsy,
new image should be taken or the procedure should be started from the
beginning.
