A flat-panel detector is exposed with nothing between the x-ray tube and detector. 5 images were acquired on 5 different days us
ing the same exposure. The pixel readings within a region of interest (ROI) are compared. What quality control test was performed? a. Detectability
b. Linearity
c. Repeatability
d. Uniformity
Since in the question it is mentioned that the falt panel detects the relation between the x-ray tube and detector. Also five images were purchased on five different days but used the similar exposure
So for the quality control test, the repeatability should be performed as the reading of the pixel is done within a region of interest also it examines the consistency of the pixel reading over time
