Question

Concerning the focal spot:

a. The area of the anode over which electrons are targeted is the actual focal spot

b. The size of the effective focal spot is the same as the actual focal spot

c. The anode angle is the angle between the central X-ray beam and the target face

d. The value of the anode angle is usually in the range of 7–30

e. Increasing the anode angle increases the actual focal spot size

Answer 1

a. True.

b. False. The effective focal spot is the area of the actual focal spot viewed from the film. Due to anode angulation, it is smaller than the actual focal spot.

c. True.

d. False. It is usually 7–20.

e. True.
