Category: Image Production-23 Select the three (3) factors that affect image distortion:

Category: Safety-47 A ferromagnetic material is:

Category: Image Production-5 Which of the following are directly related? Voltage Current Turns ratio

Category: Safety-37 To decrease patient exposure during fluorocopic procedures, the fluoroscopist can: Limit the size of the fluoroscopic field to include only the area of anatomy that is of clinical interest Employ the practice of intermittent, or pulsed, fluoroscopy to reduce the overall length of exposure Use the magnification mode instead of the full diameter of the image intensifier so that mAs will be decreased

Category: Safety-31 The lowest intensity of radiation from the patient is scattered:

Category: Safety-39 Which of the following contribute to the heterogeneous nature of the x-ray beam? Differences in energies of the incident electrons Projectile electrons interacting with many layers of the target in the anode Electrons that move to fill various shell vacancies
