  3. Welcome Course Syllabus • Locate the RT-A section on the right hand column • Find the syllabus tab • Find the Schedule tab Etudes Learning Platform • myetudes.org • Follow directions to sign up if you have not done so • Read and “Accept” syllabus.

  4. Have a good sense of humor……

  5. Welcome Study tips Do the assigned readings before class. Do the assigned readings before class. Review the Power Point Presentations Review the Power Point Presentations Review notes take in class Spend at least 2 hours outside of class for every 1 hour of classroom instruction Spend at least 2 hours outside of class for every 1 hour of classroom instruction Join a study group

  6. INTRODUCTION OF RADIOLOGIC TECHNOLOGY

  7. At the end of class: • Students will understand the term radiologic technology. • Student will be familiar with the discovery of x-rays. • Student will understand the development of the profession of Radiologic Technology • Students will understand definitions of radiation and its correlation to the EMS. • Students will be able to define ionizations of atoms and relate it to ionizing radiation. • Student will be able to state the differences between man-made radiation and natural background radiation.

  8. Terminology • Study group • Radiologic technology • Imaging sciences • X-ray • Radioactive • Radiant energy • EMS • Visible light • Wavelength • Frequency • Background radiation • Radon • Cosmic radiation • Terrestrial radiation • Man-made radiation • NCRP • Wilhelm Roentgen • Skin erythema • ASRT • Imaging modality • Certification • Registration • Radiologist • Radiographer • Radiograph • Licensure • ARRT • R.T. • C.R.T • Primary exam • Post-primary exam • Radiography • Nuclear medicine • Radiation therapy • Magnetic resonance imaging • Sonography-ultrasound • Mammography • Computed tomography

  9. Introduction to RT Preconceived Ideas regarding X-ray field

  10. The Incredible Hulk was hit by a gamma bomb in order to become the Hulk. Can this really happen? Peter Parker was bit by a radioactive spider and gains his “spidey” powers. Can this really happen? Irradiated vegetables are dangerous because they become radioactive. Is this true? After the x-ray exposure, the technologist must wait at least a minute before entering room because the radiation is still present. Cell phones give off radiation and can cause cancer. Cockroaches can survive the radiation from a nuclear blast and will take over the world when it happens. Too much radiation or too many x-rays will cause you to glow in the dark. The x-ray program is easier than the nursing program.

  11. Wilhelm Roentgen November 8, 1895

  12. W. Crookes Thomas Edison Clarence Dally G. Eastman

  13. History of X-rays Clarence Dally 1st fatality of cumulative dose of radiation Multiple reports of eye damage due to x-ray Multiple reports of skin erythema due to x-ray exposure Has this changed?

  14. History of X-rays Emergence of X-ray into a Medical Field • 1st Rad Tech considered to be Edward Jerman • Founding of ASXT in 1920 • Name change to ASRT in 1964 due to the proliferation of specialties • No longer “tech trade” but now a profession • Profession needs analytical thinking and problem solving skills

  15. History of X-rays

  16. Radiant Energy

  17. Electromagnetic spectrum Packet of energy that behaves like a particle

  18. Inversely proportional As wavelength gets shorter, frequency increases As wavelength gets longer, frequency decreases

  19. The Incredible Hulk was hit by a gamma bomb in order to become the Hulk. Can this really happen? Peter Parker was bit by a radioactive spider and gains his “spidey” powers. Can this really happen? Irradiated vegetables are dangerous because they become radioactive. Is this true? After the x-ray exposure, the technologist must wait at least a minute before entering room because the radiation is still present. Cell phones give off radiation and can cause cancer. Cockroaches can survive the radiation from a nuclear blast and will take over the world when it happens. Too much radiation or too many x-rays will cause you to glow in the dark. The x-ray program is easier than the nursing program.

  20. Ionizations

  21. Neutral charge……..equal number of positive charges (protons) and negative charges( electrons

  22. The atom on the right has a negative charge since it has one more electron that it has protons.

  23. Introduction to RT Background Radiation

  24. Background Radiation
