  1. What is Radiologic Sciences? Chapter One

  2. Terms • Radiation • Energy • Ionization • Sound • Electrocardiography • Electroencephalography • Gamma Radiation • Electromagnetic Energy • X-rays a.k.a Roentgen Rays • Radiography

  3. History of Medicine • Egypt and Mesopotamia • Greek Philosophers • Hippocrates • Hippocratic Oath • Romans • Middle Ages/Black Death

  4. 17th Century Medicine • William Harvey (1578-1657) – was the first to demonstrate the function of the heart and circulation of blood • Anton Van Leeuwenhoek (1632-1723) – described bacteria and isolated microorganisms with the microscope he created

  5. 18th Century Medicine • Edward Jenner (1796) – Vaccine for smallpox, served as the foundation for immunology. • Surgery was being experimented • Mental Health reforms • Heart drug digitalis was introduced (used to treat congestive heart failure (CHF)

  6. 19th Century Medicine “Germs cause disease!” • Louis Pasteur (1822-1895) – through his work pasteurization was developed • Robert Koch (1843-1910) – developed tuberculin to test for tuberculosis • Florence Nightingale (1820-1910) – developed foundation for modern nursing • Wilhelm Rontgen – In 1895, discovered x-rays

  7. 20th Century Medicine • Sir Alexander Fleming (1881-1955) – discovered penicillin in 1928 • Jonas Salk (1914-1995) – developed the Salk Vaccine which controls and prevents poliomyelitis • Francis Crick and James Watson (1953) – discovered the “secret to life” otherwise known as DNA which started the field on genetics

  8. History of Radiologic Technology • Wilhelm Rontgen (1895) – experimenting with a cathode and glass tubes, observed a screen with barium painted on it was emitting light (fluorescing)…he called them invisible rays or x-rays • Called them X-rays because X is the unknown variable • Most famous picture is of his wife’s hand

  9. Becoming a Radiographer • Approximately 650 Radiography programs in the United States • Upon completion of the program, you will be registry eligible • National Exam by American Registry of Radiologic Technologists (ARRT) • RT(R)

  10. Clinical Practice Standards • Appendix A in your book • Developed by American Society of Radiologic Technologists (ASRT) • Helps to define the Radiographer’s role • Helps to establish criteria to assess performance

  11. Opportunities in Radiologic Technology • Radiology • Nuclear Medicine • Radiation Therapy • Diagnostic Medical Sonography • Magnetic Resonance Imaging • Computed Tomography • Interventional Special Procedures • Cardiac Cath Lab • Mammography • Pet Scan (Positron Emission Tomography)

  12. Radiology Modalities • Cardiovascular Interventional Technology • Angiography • Cardiac Catheterization • Angioplasty

  13. Radiology Modalities cont…. • Mammography • Radiologist Assistant • Nuclear Medicine technology – Radiopharmaceuticals • Positron Emission Tomography (PET) • Radiation Therapy • Medical Dosimetrists – involved in treatment planning and dose calculation

  14. Radiology Modalities cont…. • Bone Densitometry • Computed Tomography (CT) • Diagnostic Medical Sonography (Ultrasound) • Magnetic Resonance Imaging (MRI) • Education • Management/Administration • Commercial Firms

  15. Terms • Allied Health • Technologist • Technician • Therapist • Medical Doctor (MD) • Doctor of Osteopathy (DO) – taught to manipulate muscles and bones as part of the healing process • Specialty areas – page 12

  16. Terms cont….. • Nursing • Registered Nurse (RN) – there are 2, 3 and 4 year programs • Licensed Practical Nurse (LPN) • Nurse Practitioner • Nurse Midwife • Nurse anesthetist

  17. Terms cont…. • Electrocardiographic technicians – impulses of heart • Electroencephalographic technicians – impulses of brain • MT – Medical Technologist • MLT – Medical laboratory technician

  18. Terms cont….. • Occupational Therapists – physical or emotional illnesses • Physical Therapists – restore muscle strength and coordination • Radiation Therapists – treat cancer patients • Respiratory Therapists – treat patients with breathing difficulties • Health Information Services – management of health information, patient’s health record

  19. Don’t forget to study computer terms for the next test!
