u u u u
a. Heinrich Geissler u
b. Wilhelm Roentgen u
c. Johann Hittorf u
d. William Crookes u
ANS: u B
Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen
u u u u u u u u u
udiscovered the u
x-ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges
u u u u u u u u u u u
uemitted from the negative electrode of a vacuum tube traveled in straight
u u u u u u u u u u u
ulines, produced heat, and resultedin a greenish fluorescence. William Crookes
u u u u u u u u u
udiscovered in the late 1870s that cathode rays were streams of charged
u u u u u u u u u u u
uparticles.

modified the parallelingtechnique with the introduction of the long-cone
u u u u u u u u u

8. Which of the following is an advantage of digital imaging?
u u u u u u u u u
a. Increased patient radiation exposure u u u
b. Increased patient comfort u u
c. Increased speed for viewing images u u u u
d. Increased chemical usage u u
ANS: u C
Patient exposure is reduced with digital imaging. Digital sensors are more sensitive
u u u u u u u u u u u
to x-rays than film. Digital sensors are rigid and bulky, causing decreased patient
u u u u u u u u u u u u u
comfort. The image from digital sensors is uploaded directly to the computer and
u u u u u u u u u u u u u
monitor without the need for chemical processing. This allows for immediate
u u u u u u u u u u u
interpretation and evaluation. The image from digital sensors is uploaded
