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