Radiation practice

• What is positioned above the patient in the X-ray room?

  X-ray tube and gantry
• What holds the patient during imaging?

  Table or bucky
• What does the image receptor (IR) do?

  Detects X-rays
• What is adjusted at the control panel?

  Exposure settings (kVp, mAs, etc.)
• What is the purpose of lead shielding in the X-ray room?

  Protects staff and patients
• What are controlled areas in the X-ray room?

  Restricted access during exposure
• What are safe zones for radiographers?

  Areas behind lead screens
• What facilities are included in the imaging department overview?

  Patient waiting areas, imaging rooms, changing facilities
• What is the purpose of emergency exits in the imaging department?

  Provide safe evacuation during emergencies
• What does ALARP stand for in radiation safety?

  As Low As Reasonably Practicable
• What are the three key principles of radiation safety?

  Time, Distance, Shielding
• How can radiation exposure be minimized?

  Reduce time, maximize distance, use shielding
• What type of protective equipment is used for staff and patients?

  Lead aprons
• What is the purpose of dosimeters?

  Monitor exposure levels
• Where should staff be positioned during X-ray exposure?

  Behind lead screens or in safe zones
• Why should patients be shielded during X-ray procedures?

  To protect non-essential areas from exposure
• What is the three-point ID check for patient verification?

  Full name, date of birth, address or hospital ID
• Why is patient identification important?

  Ensures correct patient undergoes examination
• What should be documented regarding pregnancy status?

  Record pregnancy status on referral form
• What should be done if pregnancy is suspected?

  Postpone non-urgent imaging
• What alternative modalities can be used if pregnancy is suspected?

  Ultrasound or MRI
• How should gender identity be approached during pregnancy checks?

  Use inclusive language
• What are the steps in the radiographic examination procedure?

  1. Preparation: Review referral and set up room
  2. Patient Interaction: Confirm ID and explain procedure
  3. Positioning: Align patient, tube, and IR
  4. Radiation Protection: Provide shielding and verify protocols
  5. Exposure: Ensure safety and make exposure
  6. Image Review: Check quality and repeat if needed
  7. Completion: Assist patient and record procedure
• What does justification of examinations ensure?

  Every X-ray is clinically warranted
• What regulations mandate the justification of radiographic examinations?

  Ionising Radiation (Medical Exposure) Regulations 2017
• What is the relationship between the X-ray tube, object, and image receptor?

  They must be aligned correctly
• How does increasing the source-to-image distance (SID) affect image quality?

  Reduces magnification and improves sharpness
• What is the effect of reducing the object-to-image distance (OID)?

  Minimizes magnification and improves resolution
• What can result from misalignment or incorrect distances in imaging?

  Distortion, magnification, loss of detail
• What is the purpose of department protocols in imaging?

  • Standardize imaging techniques
  • Ensure consistent diagnostic quality
  • Align with safety regulations and guidelines
• What are examples of protocols in the imaging department?

  Routine projections for specific exams
• Why is it important to follow department protocols?

  To ensure consistent quality and safety
• What should be done if discrepancies or equipment faults are found?

  Report them immediately
