Conclusion of Cluster 2

The three lab tests that are coveredin this week are kVp accuracy, timer accuracy and Dr flatfield QC. The kvP accuracy test is to check if theselected kVp from the control console is actually the same as the measured kVpfrom a kVp meter. From the kVp accuracy table, the averaged measured kVp inroom 5 falls under the acceptance range according to HARP and SC35. TimerAccuracy is to test the measured the actual exposure time. Results show bothroom 3 and 6 are functioning properly and the timers are well calibrated as theresults collected are within the acceptable range enforced by SC 35 and HARP. ForDR flatfield QC, by performing a QAP, we can tell how many dead pixels arepresent in the detector. The result showed there was only one dead pixel androom 6 passed the quality control test. Although, all the rooms are functioning properly, it does not mean therooms do not require any more quality control tests. In fact, QC tests shouldbe carried out as the same way as they are to make sure the equipments aremaintain at a high level performance.
