The target of the X-ray tube is angulated to produce all the following effects, EXCEPT
Correct Answer: To energize the photons
Description: The target is inclined about 20 degrees to the central ray of the x-ray beam; this causes the effective focal spot to be approximately 1 mm × 1 mm, as opposed to the actual focal spot, which is about 1 mm × 3 mm.
This smaller effective focal spot results in a small apparent source of x rays and an increase in the sharpness of the image, with a larger actual focal spot size to improve heat dissipation.
