    Study Notes

    X-ray in Radiology

    Introduction to X-rays

    • X-rays are a type of electromagnetic radiation with high energy and frequency
    • Discovered by Wilhelm Conrad Röntgen in 1895
    • Used in medical imaging to produce diagnostic images of internal structures

    Principles of X-ray Imaging

    • X-rays interact with tissue and bones, producing attenuation (absorption or scattering)
    • Dense materials like bone absorb more X-rays, while soft tissues absorb less
    • The resulting attenuation pattern is detected by an X-ray detector, creating an image

    X-ray Equipment

    • X-ray tube: produces X-rays through high-voltage electrical discharge
    • X-ray detector: converts X-ray energy into a visible image
    • Image intensifier: amplifies the X-ray signal to improve image quality
    • Digital radiography systems: use digital sensors and computers to produce digital images

    X-ray Imaging Techniques

    • Conventional radiography: uses X-ray film or digital detectors to produce 2D images
    • Computed radiography (CR): uses digital detectors and computers to produce digital images
    • Digital radiography (DR): uses digital sensors and computers to produce digital images
    • Fluoroscopy: uses continuous X-ray exposure to guide interventional procedures

    X-ray Applications in Radiology

    • Diagnostic imaging: evaluates injuries, diseases, and conditions (e.g., bone fractures, lung diseases)
    • Interventional procedures: guides procedures like biopsies,angiograms, and orthopedic surgeries
    • Therapy: used in radiation therapy to treat cancer and other conditions

    Safety Considerations

    • Radiation exposure: X-rays can cause DNA damage and increase cancer risk
    • Radiation protection: uses shielding, distance, and time limits to minimize exposure
    • ALARA (As Low As Reasonably Achievable) principle: minimizes radiation exposure to patients and staff

    Introduction to X-rays

    • X-rays are a high-energy, high-frequency type of electromagnetic radiation
    • Discovered by Wilhelm Conrad Röntgen in 1895
    • Used in medical imaging to produce diagnostic images of internal structures

    Principles of X-ray Imaging

    • X-rays interact with tissue and bones, producing attenuation (absorption or scattering) due to differences in density
    • Bone absorbs more X-rays, while soft tissues absorb less
    • Attenuation pattern is detected by an X-ray detector, creating an image

    Safety Considerations

    • Radiation exposure from X-rays can cause DNA damage and increase cancer risk
    • Radiation protection uses shielding, distance, and time limits to minimize exposure
    • ALARA principle minimizes radiation exposure to patients and staff
