3.0 Unit Description
The three major hardware components of the Affinity Series are:
• the Gantry
• the C-arm
• the Control Panel
The following paragraphs briefly describe each of the major hardware components.
3.1 Gantry and C-Arm
Refer to Figure 1-2 throughout the following. The Gantry houses the electronics which
produce high voltage at the energy levels needed for mammography. The mechanical
assemblies which position the C-arm (height and rotation), the input transformer, the
emergency OFF switches and most of the system electronics are also in the Gantry. LED
readouts on the left and right side of the Gantry show the C-arm angle.
The Gantry also supports an externally mounted radiation shield that protects the operator
from exposure during the exam, and houses the input power connector panel and
Footswitch receptacles.
The C-arm is made up of the following major assemblies:
• X-ray Tubehead
• Compression Device
• Image Receptor Support Device
A pivot mechanism connects the C-arm to the Gantry. Pushbutton switches on each side of
the C-arm, and on the tubehead, control C-arm movement, Compression Release,
Compression up/down, and the light field lamp. The design of the C-arm permits
examination of standing, sitting or recumbent patients.
