You have just taken a CR radiograph of a patient's knee and the S# is 225. Unfortunately, the image has some degree of motion distortion and needs to be repeated using the same exposure settings. In repeating the image, the new image shows no motion but the S# is now 400. No changes were made to collimation, patient position, exposure techniques, etc. Based upon this new S# value,
a. exposure reproducibility is suspect.
b. the mR/mAs is equal.
c. the exposure reproducibility is within tolerable limits.
d. all of the above
