Question

19 multiple choice 1 point kilovoltage is the primary controlling factor of x - ray beam quantity. filtration thickness. x - ray beam quality. x - ray beam intensity. 20 multiple choice 1 point an increase in kvp by 15 percent will cause an approximate ____ in the exposure to the receptor. 15 percent increase tripling doubling quadrupling

Explanation:

1. Kilovoltage (kVp) is the primary factor that controls the quality of the x - ray beam. Higher kVp values result in more energetic x - rays, which means a higher - quality beam. X - ray beam quantity is mainly controlled by milliamperage (mA), filtration thickness is related to the material and its thickness used to filter the x - ray beam, and x - ray beam intensity is related to both mA and kVp but kVp is not the primary for intensity control.
2. According to the 15% rule in radiography, an increase in kVp by 15 percent will cause an approximate doubling in the exposure to the receptor.

Answer:

1. x - ray beam quality.
2. doubling
