a. Increased patient radiation exposure l0 l0 l0


b. Increased patient comfort l0 l0


c. Increased speed for viewing images l0 l0 l0 l0


d. Increased chemical usage l0 l0




ANSWER:C C l0


Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to
l0 l0 l0 l0 l0 l0 l0 l0 l0 l 0 l0 l0 l


0x-
rays than film. Digital sensors are rigid and bulky, causing decreased patient comfort. The i
