11.3.2 Inspection of Image Quality

As uniformity correction is applied in normal use and in QC uniformity checks, there is a risk that
severe image imperfection has been covered by uniformity correction updated by the user. There-
fore a flood image should be acquired without uniformity correction applied.
For each detector, acquire an intrinsic 3 million count static image with uniformity set to None,
using a Tc-99m or Co-57 point source. Some faint lines and shadows along the edges are accept-
able, but there must not be pronounced tube patterns, holes or bands in the image.

11.3.3 Check of Motion Limits

With the hand controller, move the detector as far as it will go in all directions (vertical, horizontal
and rotate). During these checks, position the detector to avoid conflicts with the patient table.
•
Verify that the vertical motion axis does not enter into any of the ultimate limits.
•
Verify that the horizontal motion axis does not enter into any of the ultimate limits.

Inspection
Check cables connected to the PC and monitor.
Check for damage to insulation especially around cable
clamps
Check that all external cables are secured in connector
clamps where applicable
Check the security and condition of all external panels
on gantry and PC
Check all collimators for damage to septa and to locking
mechanism
Check the uniformity of the detectors by an intrinsic or
extrinsic QC check
Check the center of rotation for all collimators
Check the functionality of all collimator, detector and
gearbox collision sensors
Check the hand controller for cracks and damage.
Check the connection points on the hand controller and
on the gantry
Check the table pallet and mattress for damage
Check both E-Stop buttons for correct operation. When
an E-Stop button is activated, no gantry motions should
be possible,
the yellow E-Stop indicator should be on and the green
motor power indicator should be off
