2. Calibrations of the unit Prerequisites: –s2terminal open and connected to OP300 in normal mode –Cliniview software open and image capture activated How to start: S2terminal must be connected to the unit - select in the control panel - select “Service” in the control panel After calibrations are completed, service indicator must be cleared with s2terminal command

3. Alignment and QA Tools Pan alignment cone assembly QC PhantomCT Geometry tool Leveling base

4. Calibrations during installation Necessary calibrations –Preheat calibration –mA calibration –3D collimator calibration –PAN collimator calibration –PAN geometry calibration –3D geometry calibration(s) –3D lasers alignment –PAN lasers alignment –3D pixel calibration –PAN pixel calibration –3D QC program

5. Acceptance limits Passed Calibration program is successfully done. Move on to next calibration. Not passed Adjustment is still needed. Follow the instructions the image (if any) and take another exposure. Some calibration programs are iterative and needs a few repetitions. Failed System could not decide what adjustment should be done in order for the calibration to succeed. This calibration status is always the result of some error condition. Taking another exposure will not help. The image may give a hint on what the problem is (e.g. no radiation, collimator severely tilted, image data corrupted…).
