Introduction to Radiologic Technology & Health Care - 1

• Their role is crucial in ensuring that patients receive safe, effective, and accurate doses of radiation during their cancer treatment.
• Radiation therapists are responsible for ensuring that patients receive safe and effective radiation therapy.
• Nuclear medicine technologists administer radiopharmaceuticals to patients and perform nuclear medicine studies.
• Radiation therapists are responsible for administering radiation treatments according to the prescribed plan developed by the oncologist or radiation oncologist.
• Radiation therapists work closely with other healthcare professionals, including physicians, nurses, and radiographers, to ensure coordinated patient care.
• There are more than 10,000 radiography programs that offer education leading to eligibility to take the certification examination administered by the American Registry of Radiologic Technologists (ARRT).
• MRI technologists operate magnetic resonance imaging (MRI) machines that create detailed images of body structures using magnets and radio waves.
• They use imaging techniques such as PET scans, SPECT scans, and bone scans to create detailed images of the inside of the body.
• Their role involves working closely with physicians and other medical professionals to interpret results and make recommendations for further care.
• Nuclear medicine technologists administer radiopharmaceuticals to diagnose or treat diseases.
• The development of radiology is in large measure a story of the development of hardware
• Early scientists and crafts workers made possible the production of x-rays
• 1st century AD shows evidence of experimentation with the chemical and physical properties of matter
• Archimedes


  Explained the reaction of solids when placed in liquids
• Democritus


  Described materials as being composed of ultimate particles
• Thales


  Discovered some effects of electricity
• Three specific aspects of physical science that paved the way to the discovery of x-ray

  • Electricity
  • Vacuums
  • Image Recording medium
• Evangelista Torricelli


  Produced the first recognized vacuum when he invented a barometer in 1643
• Otto van Guericke


  Invented an air pump capable of removing air from a vessel or tube in 1646
• Robert Boyle and Herman Sprengle

  Repeated the vacuum experiment in 1659 and 1865
• William Gilbert


  One of the first men who extensively studied electricity and magnetism
• Robert Boyle

  Experiments with electricity merit him a place among serious investigators
• Isaac Newton


  Build and improved static generator
• Charles DuFay


  Distinguished two different kinds of electricity while working with glass, silk, and paper
• Abbe Jean Antoine Nollet


  Made a significant improvement in the electroscope
• Benjamin Franklin


  Conducted many electrical experiments and was one of the pioneers of electricity
• William Watson


  Demonstrated a current of electricity by transmitting electricity from a Leyden jar through wires and vacuum tubes
• William Morgan


  Conducted experiments with electrical discharge and noticed the coloration and difference in color of partially evacuated tubes
• Michael Faraday


  Induced an electric current by moving a magnet in and out of a coil in 1831, leading to the concept of electromagnetic induction
• H.D. Ruhmkorff


  Made the most significant improvement on induction coils in Paris
• Johan Wilhelm Hittorf


  Conducted several experiments with cathode rays, streams of electrons emitted from the surface of a cathode
• William Crookes


  Furthered the study of cathode rays and demonstrated that matter was emitted from the cathode with enough energy to rotate a wheel placed within a tube
• Phillip Lenard


  Furthered the investigation of cathode rays and found that they could penetrate thin metal and project a few centimeters into the air
• William Goodspeed


  Produced a radiograph in 1890, recognized only in retrospect after the discovery of x-rays by Roentgen
• Image recording material


  • Photographic recording techniques
  • Significant improvement of image-recording material and cathode rays experiments
• 1727 – Johann Henry Scholtz– produce
