GXMO Study Guide Questions and
Answers Latest Version Rated A+
What is the role of a GXMO in radiology?


✔✔The role of a GXMO is to assist in performing radiographic exams under the supervision of a

licensed radiologic technologist or physician.




What is the purpose of radiographic collimation?


✔✔Collimation is used to restrict the X-ray beam to the area of interest, reducing unnecessary

radiation exposure to the patient and surrounding tissues.




What is the importance of patient identification in radiology?


✔✔Proper patient identification is essential to avoid errors, ensuring the correct patient receives

the correct exam and treatment.




What does the term "radiation dose" refer to in radiology?


✔✔Radiation dose refers to the amount of ionizing radiation absorbed by the body during a

radiographic procedure.

,What is the primary function of a radiographic grid?


✔✔A radiographic grid is used to reduce scatter radiation and improve image contrast by

filtering out scattered X-rays.




What does "ALARA" stand for in radiology?


✔✔ALARA stands for "As Low As Reasonably Achievable," a principle focused on minimizing

radiation exposure to both patients and staff.




What is the role of the X-ray tube in radiography?


✔✔The X-ray tube generates X-rays by accelerating electrons and directing them toward a

target, where they produce the X-ray beam.




What is the primary function of kVp in radiography?


✔✔kVp (kilovolt peak) controls the energy and penetrating power of the X-ray beam, affecting

image contrast and patient exposure.




What is the difference between contrast and density in radiographic imaging?


✔✔Contrast refers to the difference in shades of gray in an image, while density relates to the

overall blackness or darkness of the image.

2

, How does body habitus affect radiographic imaging?


✔✔Body habitus can affect positioning and technique, as thicker body parts may require

adjustments in exposure to produce high-quality images.




What is the significance of mA (milliamperage) in radiographic imaging?


✔✔mA controls the quantity of X-rays produced and influences image density, with higher mA

settings leading to more X-ray photons being generated.




What is the purpose of lead shielding in radiology?


✔✔Lead shielding is used to protect parts of the body not involved in the imaging procedure

from unnecessary radiation exposure.




What is the importance of proper positioning in radiography?


✔✔Proper positioning ensures the anatomical structures are correctly aligned for accurate and

diagnostic-quality radiographic images.




What is the role of the radiologist in interpreting radiographic images?
