Question

Quizplus · Accepted Answer

kVp controls the average energy of the x-ray beam and affects image receptor exposure.

Answer: A
 mAs directly controls image receptor exposure.

Answer: C
 The density maintenance formula is a mathematical equation used to determine the amount of exposure necessary to maintain image receptor density when making changes to technique factors.

Answer: D
 Radiographic grids are used to reduce scatter radiation and improve image quality, but also require an increase in technique factors to maintain image receptor exposure.

Answer: E
 The 15% rule is a guideline used to determine the necessary adjustment of kVp when changing mAs to maintain image receptor exposure.

Answer: F
 The anode heel effect is a variation in radiation intensity across the x-ray field due to the angle of the x-ray beam and the geometry of the anode.

Answer: G
 Focal spot size indirectly affects image receptor exposure by affecting recorded detail and spatial resolution.

Answer: H
 Recorded detail is the ability to distinguish small objects in the image, which is affected by factors such as focal spot size and motion blur.

Answer: I
 EI value (Exposure Index) is a standardized value used to indicate image receptor exposure and ensure consistent image quality across different imaging systems.

Answer: J
 Visibility of detail is the ability to distinguish different shades of gray in the image, which is affected by factors such as image receptor exposure, contrast, and noise.
