| Question | Answer |
|---|---|
| x-ray | form of invisible, high frequency electromagnetic raidation |
| mammography | x-ray of soft tissue of the breast |
| radiographer | person qualified to take an x-ray |
| lateral | pt is positioned with x-ray entering from the side |
| oblique | diagonal, angel little to the side |
| radiolucent | substances easier to pen by x-ray, appears dark, ex-air, lungs, tissue fat |
| PA | posterior anterior, patient faces film, xray enters from back |
| Imaging | production of visual output, using x-ray sound waves and magentic fields |
| diagnostic radiology | the use of x-ray for diagnostic purposes |
| AP | Anterior Posterior, patient faces toward x-ray, back is to film, x-ray beams enter from front |
| Craniocaudal | beam enters at the cranial end of part being examined & exits at the caudal end. |
| Radiology | the study of diagnostic and therapeutic usage of x-rays |
| Projection | path the x-ray beam follows through body, from entrance to exit |

| DigitalRadiography | any method of x-ray imaging,uses a computer to store and manipulate the data, used for special application such as fluroscopy and angiography |
| CT scan | Computed tomography-uses radiation, fan shaped beam tht rotates around the pt, to produc cross section of body. |
| MRI | Magnetic Resonance Imaging-uses electromagnetic energy w/o use of radioactive x-rays, non-invasive, provides excellent imaging of soft tissue-anybody part |
| Fluroscopy | visualize structure, body part in motion, use to see internal organs in motion, with radiation (organs in motion) |
| PET | Position Emission Tomography-uses radiopharmacetucal to produce enchanced images of selected body organs/areas |
| VCU | Voiding Cystourethagram |
| Ultrasound | Non-invasive, high frequency sound waves to produce echos within the body |
| Radiation Field | Where the x-ray beam coming from the x-ray machine, part to be x-rayed is placed in the radiation field, btw the x-ray tube and the flim. |
| Ultrasound | non-invasive high frequency soundwaves to produce echos within he body |
