What is the purpose of lead aprons in radiology?
✔✔ To shield parts of the body from radiation exposure.
Why is it important to verify patient identity before an exam?
✔✔ To ensure the correct patient is imaged and avoid medical errors.
What does PACS stand for in radiology?
✔✔ Picture Archiving and Communication System.
What is the function of DICOM in medical imaging?
✔✔ To standardize the storage and transfer of medical images.
What is the importance of patient history in radiology?
✔✔ It helps identify contraindications and guides the imaging procedure.
1
,What is fluoroscopy used for?
✔✔ To provide real-time moving images of internal structures.
How is digital radiography different from conventional radiography?
✔✔ Digital radiography uses electronic detectors, while conventional uses film.
What are the three cardinal rules of radiation protection?
✔✔ Time, distance, and shielding.
What is the significance of kVp in X-ray imaging?
✔✔ It determines the energy and penetrating power of the X-ray beam.
What safety measures should be taken for pregnant patients?
✔✔ Avoid exposure unless necessary and use protective shielding.
Why is continuing education important for radiologic technologists?
✔✔ To stay updated on technology, techniques, and safety practices.
2
,What is a dosimeter, and why is it used?
✔✔ A device that measures radiation exposure to ensure it remains within safe limits.
What is radiologic technology?
✔✔ The use of radiation to create images of the body for medical diagnosis.
What is the role of a radiologic technologist?
✔✔ To operate imaging equipment and ensure patient safety during procedures.
Why is patient positioning critical in radiologic exams?
✔✔ It ensures accurate images and reduces the need for repeat exposures.
What does ARRT stand for?
✔✔ American Registry of Radiologic Technologists.
Why is maintaining confidentiality important in radiology?

3
, What is the primary purpose of X-rays in medicine?
✔✔ To visualize internal structures of the body for diagnostic purposes.
What is a cathode in an X-ray tube?
✔✔ The negatively charged electrode that emits electrons.
What does the anode in an X-ray tube do?
✔✔ It acts as the target for electrons to produce X-rays.
What is scatter radiation?
✔✔ Radiation that is deflected from its original path during interaction with matter.
What does ALARA stand for, and why is it important?
✔✔ As Low As Reasonably Achievable, to minimize radiation exposure.
What is the purpose of shielding in radiology?
✔✔ To protect the patient and staff from unnecessary radiation.
