Test 7: Mechanical Tests
Objective
To ensure the mechanical integrity of the system
Required Equipment
a)
Compressible phantom
b)
ACR (RMI 156) phantom
c)
Stop watch
d)
Compression plate 24 x 30 cm
Procedure
1.
Check that the control panel lights up to show that the power is switched on.
2.
Turn the swivel-arm system to 180° (tube head is straight upside down). Lower
the system as close to the floor as possible. Check that system stops above the
floor. Raise and turn the swivel-arm system back.
3.
Check the motorized movements for smooth running and normal function.
4.
Check that all foot switches operate correctly.
5.
Check that the height adjustment and rotation of the swivel-arm system are
blocked, when the displayed compression force is ≥ 30 N.
6.
Check the emergency stop button for correct function. Note that with the button
depressed, all motorized movements shall be blocked, and x-ray release is not
possible. Release emergency stop button, Mammo unit will be reset and
examination can be continued. Confirm message on AWS.
7.
Check that object table surface and all compression plates show no sharp edges
or cracks which could injure the patient.
8.
Check that the edges of the radiation shield are clearly defined so that the user is
aware of the outline.
9.
Check that the manual compression/decompression functions properly.
10. If automatic decompression is set up the compression plate should release
compression after an exposure automatically. The deactivation of automatic
release should also work correctly.
11. Check that the decompression button on the control box works correctly.
12. Check that the emergency decompression button works correctly.
