Intro to Rad Ch1
| Question | Answer |
|---|---|
| Energy | The capacity to work |
| Radiation | Energy transmitted in waves though space or matte |
| Radiography | The practice of making x-ray images |
| Radiograph | The image produced using x-ray |
| Energy Types | Mechanical, Electrical, Heat, Nuclear,Electromagnetic |
| X-Rays | Roentgen Rays |
| Radiation | Energy that is transmitted in waves through space or a medium (matter, air). The shorter the wavelength, the higher the energy |
| Non- Ionizing Radiation: | Wavelength longer than one nanometer |
| William Conrad Roentgen | X-Rays “discovered” November 8,1895 |
| November 8, 1895 | Produced the first known x-ray, an image of his wife’s hand |
| Diagnostic Services | Perform tests and services to aid in the diagnosis or grading of a medical condition, confirm or rule out the presence of a disease or condition |
| Therapy Services | Provide services that treat conditions, assist in recovery or teach techniques that aid in dealing with a condition |
| Radiologist | Physician who specializes in Radiology |
| Technologist | A person qualified to provide medical imaging services in a specific modality (Radiographer) with applicable training, licensure or certification |
| Technician | Non R.T. with limited professional training (BMO, Limited Scope |
| Mammography | Uses X-ray to image breast tissue |
| Interventional Radiography | Uses X-ray/ fluoroscopy in interventional lab. Usually includes Imaging of blood vessels. Also perform other treatments such as stone removal/stent placement. May include Cardiac Catheterization |
| Nuclear Medicine | Uses Radioactive material Radioactive material bonded with medication to be processed by the body. Patient administered Radioactive material orally or by injection. |
| Radiation Therapy | Uses both electrically generated Radiation and Radioactive materials. Exposure at doses high enough to damage tissue. Targeted for maximum damage to malignant tissue and minimized |
| Bone Densitometry | Uses X-ray to measure bone density |
| Computed Tomography | Machine generates 360 images that are reconstructed by a computer. Produces images that appear as “slices”through the body |
| Magnetic Resonance Imaging. (MRI) | Does not use Ionizing Radiation. Uses strong magnetic fields and Radio waves. Computer reconstruction of images in “slice” or 3-D format |
