A flat-panel detector is exposed with nothing between the x-ray tube and detector. 5 images were acquired on 5 different days using 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

c. Repeatability

Explanation:

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

Hence, the correct option is c.  

plot immersion i am not fully sure with it though

its b

hope this
