sw sw sw sw sw sw sw sw sw sw sw sw sw
heat, and resultedin a greenish fluorescence. William Crookes discovered in the late

sw sw sw sw sw sw sw sw sw
a. Increased patient radiation exposure sw sw sw
b. Increased patient comfort sw sw

ANSWER: C sw
Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to
sw sw sw sw sw sw sw sw sw sw sw sw
x-rays than film. Digital sensors are rigid and bulky, causing decreased patient
sw sw sw sw sw sw sw sw sw sw sw sw
comfort. The image from digital sensors is uploaded directly to the computer and
