When changing the PID length from 8 inches (20.5 cm) to 16 inches (41 cm), what corresponding change must be made to maintain image density?
a. Decrease exposure time.
b. Increase exposure time.
c. Decrease kilovoltage.
d. Increase kilovoltage.
b. When changing the PID length, a corresponding change must occur in the exposure time to maintain image density. Because the x-rays emerging from the tube travel in straight lines and diverge from one another, it follows that the intensity of the beam is reduced. So, to maintain image density, the exposure time should be increased.
