ANSWER: B v
Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen discovered the

x-ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges emitted from the
v v v v v v v v v v v v v v
negative electrode of a vacuum tube traveled in straight lines, produced heat, and resultedin a
v v v v v v v v v v v v v v v v
greenish fluorescence. William Crookes discovered in the late 1870s that cathode rays were

streams of charged particles.

v v v v v v v v v
a. Increased patient radiation exposure v v v
b. Increased patient comfort v v
c. Increased speed for viewing images v v v v
d. Increased chemical usage v v
ANSWER: C v
Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x-rays than
v v v v v v v v v v v v v v
film. Digital sensors are rigid and bulky, causing decreased patient comfort. The image from

digital sensors is uploaded directly to the computer and monitor without the need for chemical
