Increasing kilovoltage peak (kVp) has what effect on image contrast?
Answer: Lower contrast with more shades of gray
Higher kVp produces more penetrating x-rays, giving a longer scale of contrast.
Doubling the milliamperage (mA) while keeping time constant will:
Answer: Double the number of x-rays produced
mA controls the quantity of x-ray photons, which is directly proportional.
According to the inverse square law, doubling the distance from the source changes beam intensity to:
Answer: One fourth
Intensity is inversely proportional to the square of the distance.
The primary purpose of a radiographic grid is to:
Answer: Absorb scatter radiation to improve contrast
Grids absorb scattered photons that would otherwise reduce image contrast.
Why is overexposure of a patient a concern with digital receptors?
Answer: Images may still look acceptable, hiding the excess dose
Wide dynamic range and software compensation can mask overexposure, leading to dose creep.
What is a main dose-reduction advantage of rectangular collimation compared with round collimation?
Answer: Reduces the volume of tissue exposed
Rectangular collimation matches the beam to the receptor size, cutting patient dose substantially.
Compared with D-speed film, F-speed film requires:
Answer: Less exposure
F-speed film is roughly 60 percent faster than D-speed, so it needs less radiation.
