5 Operating procedures
86500-IMG rev 3 GE Healthcare 27
1C-Arm
When the C-Arm foot switch is pressed, only the C-Arm is driven towards
the tube head at a slow speed.
2 PADDLE
When the Paddle foot switch is pressed, only the compression paddle is
driven towards the image receptor. The collimator light is turned on
automatically at the same time. Before the paddle touches the breast the
speed of the paddle is high. Once the breast is compressed the speed
slows down. Both the drive speed and the threshold where the speed
change occurs on contact with the breast are adjustable by your service
technician.
3ECS
When the ECS foot switch is pressed, the C-Arm is driven towards the tube
head and the compression paddle is driven towards the image receptor,
so that the paddle appears to be stationary in relation to the patient. This
means that the cassette holder (Bucky or magnification tunnel) is used to
apply the compression to the breast against the ‘stationary’ paddle.
4REL
When the REL foot switch is pressed, the C-Arm is driven towards the
image receptor to its rest position and the compression paddle is driven
towards the tube head, removing compression to the breast. As long as
the C-Arm is not yet in its rest position, the paddle is driven at the same
speed as the C-Arm, thus the paddle appears to be stationary. Once the C-
Arm movement stops, the compression paddle is driven towards the tube
head until it reaches the upper microswitch.
5 Z-UP
When the Z-UP foot switch is pressed, the carriage is driven towards the
tube head.
6Z-DOWN
When the Z-DOWN foot switch is pressed, the carriage is driven towards
the image receptor.
There are two compression
foot pedals supplied with the
Diamond. These are
connected with cables to the
back of the column (3 and 4
in the image).
