CT Registry Review 1
CT is commonly referred to as all of the following names except:
a) computed tomography
b) computerized axial tomography
c) CAT-scan
d) digital subtraction angiography - Answer-D
What control does the operator have over the x-rays in a CT exam:
a) the temperature and color of x-rays can be tuned
b) the phase and frequency of the x-rays can be adjusted
c) the energy level and the quantity of x-rays can be selected
d) the volume and tone of the x-rays can be dialed - Answer-C
X-rays are produced whenever fast moving electrons collide with any form of matter because:
a) the electrons splits into two x-ray photons of equal energy upon impact with the matter
b) the electron loses kinetic energy which is converted into the emission of an x-ray photon
c) the electron converts the electron is collides with into an x-ray photon
d) all of these - Answer-B
, Which of the following statements is true:
a) kV is the voltage potential between the tube cathode and anode while mA controls the filament
current and, thus, ultimately the temperature of the cathode filament
b) kV controls the energy level of the x-ray photons and mA controls the number of x-ray photons
emitted from the tube
c) both a and b are correct
d) none of these - Answer-C
Which of the following does not affect the quantity of x-rays that completely penetrates the patient:
a) the distance that the x-ray photons must travel on their course through the patient's body
b) the molecular composition of the tissues through which the x-ray photons pass
c) the type of detector material used
d) both a and b - Answer-C
computers is: - Answer-Magnetic optical disk (MOD)
Which of the following statements is FALSE regarding the maxillary sinuses?
1. They are the largest sinus cavities
2. They lie above the roots of the upper teeth
3. They drain through the infundibulum
4. They lie lateral to but not within the maxillary bones - Answer-They lie lateral to but not within the
maxillary bones
The dorsal tendon group is responsible for: - Answer-Extending the fingers and wrist
