    Study Notes

    Certification and Requirements

    • Primary certification in radiography, nuclear medicine, or radiation therapy is mandatory for practitioners.
    • Clinical requirements must be met to ensure competency in the field.

    Imaging Modalities

    • Computed Tomography (CT)

      • Utilizes ionizing radiation to generate cross-sectional images.
      • Fast imaging process compared to MRI.

    • Magnetic Resonance Imaging (MRI)

      • Employs magnetic fields and radio waves to create detailed images.
      • Can be applied to the entire body or specific cross-sectional areas.
      • Not suitable for patients with metal implants due to magnetic interference.

    • Nuclear Medicine

      • Involves the use of radioactive isotopes for imaging.
      • Radiation emits from within the patient, providing functional information.

    • Mammography

      • Specialized breast imaging technique using ionizing radiation.
      • Involves medical dosimetrists for treatment planning and dose calculation.

    • Ultrasound (Sonography)

      • Uses high-frequency sound waves for imaging instead of ionizing radiation.
      • Produces "real-time" images and utilizes techniques similar to Navy sonar.

    Radiation Therapy

    • Focuses on treating diseases, particularly cancer, using high levels of ionizing radiation (megavolts).
    • Requires primary certification for practice.

    Career Opportunities and Education

    • Various pathways available, including formal education and on-the-job training.
    • Roles include technologists, radiographers, and radiologist assistants.
    • Opportunities in sales and application specialists within the medical imaging market.

    Safety Concerns

    • X-ray exposure can pose risks, including skin dryness, erythema, and potential for cancer if exposure is excessive.
    • Importance of adhering to radiation safety practices for oneself and others.

    Imaging Procedures

    • Non-exhaustive list of medical imaging modalities includes:
      • Ultrasound
      • Angiography
      • Computed Tomography (CT)
      • Magnetic Resonance Imaging (MRI)
      • Positron Emission Tomography (PET)
      • Nuclear Medicine
      • Mammography
      • Radiation Therapy

    Practice Standards

    • Continuing education and training are vital for maintaining certification and staying current in imaging technologies.
    • Registries exist for both local and out-of-state certifications, emphasizing the mobility and diversity of the profession.

    Advancements in the Profession

    • The field has evolved from a technical trade to a recognized profession requiring analytical thinking and problem-solving skills.
    • Historical context highlights the duality of x-rays being beneficial for diagnosis while posing health risks due to excessive exposure.
