Question | Answer |

The four prime factors of radiographic exposure are: | Exposure Time, Milliamperage, Kilovoltage, Source-Image Distance |
The prime factor that controls the wavelength of the x-ray beam is: | Kilovoltage |
The prime factor that controls the rate at which x-rays are produced: | Milliamperage |
The mAs value of an exposure is varied to provide control of: | Optical Density |
The imaging system that produces an instantaneous digital image on a monitor: | Digital Radiography(DR) |
The hardware and software for managing digital images: | Picture Archiving Communication System(PACS) |
Three factors affected by the mA setting: | Optical Density, Anode Heat, Radiation Intensity |
What is the primary factor for controlling contrast? | kVp |
The inverse squares law states that radiation intensity is inversely proportional to the square of the: | Source-Image Distance(SID) |
A variation in the size or shape of the image in comparison to the object it represents: | Distortion |
