Radiology Final Exam Questions and
Answers Latest Version Already Passed
What is the primary function of the X-ray tube in radiology?


✔✔The X-ray tube produces X-rays by directing electrons toward a target, which then emits

radiation.




How does collimation affect the quality of a radiographic image?


✔✔Collimation helps to reduce unnecessary radiation exposure and improves image quality by

limiting the area of exposure.




What is the significance of the SID (Source-to-Image Distance) in radiography?


✔✔A longer SID reduces magnification and distortion, resulting in a clearer and more accurate

image.




What is the purpose of the anode in the X-ray tube?


✔✔The anode serves as the target for the electrons, where they are converted into X-rays.




How does the kVp (kilovolt peak) influence the X-ray image?


1

,✔✔Increasing the kVp enhances the penetrating power of the X-rays, leading to better tissue

differentiation and reduced image noise.




Why is the use of protective lead aprons recommended during radiographic procedures?


✔✔Lead aprons protect patients from unnecessary radiation exposure, particularly to sensitive

organs.




What is the role of the grid in radiography?


✔✔The grid helps to reduce scattered radiation, improving image contrast by absorbing some of

the scattered rays before they reach the film or detector.




What is the effect of increasing the mAs (milliampere-seconds) on a radiographic image?


✔✔Increasing the mAs results in greater exposure, leading to a more detailed and higher-quality

image.




How does patient positioning impact the accuracy of radiographic results?


✔✔Proper positioning ensures that the area of interest is clearly visualized, reducing the risk of

distortion or overlap in the image.




2

, What is the purpose of the filtration in an X-ray machine?


✔✔Filtration removes low-energy X-rays from the beam, reducing unnecessary radiation

exposure to the patient.




How does the distance from the radiation source affect patient exposure?


✔✔The exposure to radiation decreases significantly as the distance from the source increases,

following the inverse square law.




What is the primary purpose of an exposure indicator in digital radiography?


✔✔The exposure indicator helps to assess whether the exposure was sufficient, underexposed, or

overexposed, guiding proper image quality control.




What does the term "magnification" refer to in radiographic imaging?


✔✔Magnification occurs when the object being imaged appears larger than its actual size due to

improper positioning or increased SID.




Why is it important to avoid motion during a radiographic procedure?


✔✔Motion causes blurring in the image, which can make it difficult to accurately diagnose and

interpret the results.
