What two factors affect the quality of an x-ray?

mA and exposure time
Distance and filter
Filtration and kVP
mA and kVP

The correct answer is: Filtration and kVP

X-ray quality can be influenced by several technical factors, including milliamperage (mA), kilovoltage peak (kVP), and filtration. However, only two of these factors significantly affect the quality of the x-ray image. These are the filtration and kVP settings. Option A, mA and exposure time, affects the intensity and quantity of x-rays produced, but does not impact the quality of the image. Option B, distance and filter, can indirectly affect the quality of the image by impacting the amount of radiation reaching the sensor, but they are not the primary factors that determine the quality. Option D, mA and kVP, is incorrect because it includes only one factor (mA) that affects image quality. Overall, option C, filtration and kVP, is the best answer because filtration removes low-quality x-rays from the beam before it reaches the patient, while kVP affects the contrast and sharpness of the image. Therefore, these two factors have the most direct impact on the quality of an x-ray image.
