b b b b b b b b b


a. Increased patient radiation exposure b b b


b. Increased patient comfort b b


c. Increased speed for viewing images b b b b


d. Increased chemical usage b b




ANSWER: C b


Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x-rays
b b b b b b b b b b b b b


than film. Digital sensors are rigid and bulky, causing decreased patient comfort. The image
