A radiologic technologist notices that the exposure indicator value is significantly
higher than the usual range after performing a chest radiograph. What could be the
most likely reason for this observation?

It determines the clarity and resolution of the images
You are performing a mobile chest x-ray on an asthenic patient. The mAs and kVp are
set as low as possible, but you still expect the image receptor exposure to be
excessive for a patients body habitus. Another way to decrease image receptor
exposure would be to:
