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 |
Shield | vest, that protects patients and tech |
Flim Badge | Device for monitoring radiation exposure. also known as dosimeter |
Radiologist | person who specializes in reading x-rays |
William Roentgen | German physicist-discovered x-rays |
Radiopaque | substances that are difficult to penetrate by x-rays, does not allow x-rays to pass through metal, bone. Objects appears white.light |
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 |
