radiographic(redirected from radiographic geometry)
Also found in: Dictionary.
adj relating to the process of radiography, the finished product, or its use.
n the beam that emanates from a radiographic tube. X-ray photons produced at the target in the tube leave the tube as a divergent beam.
radiographic film, air bubbles on,
n See film fault, white spots.
radiographic film sizes,
n nonscreen films (e.g., No. 0, 22 × 35 mm; No. 1, 24 × 40 mm, No. 2, 31 × 41 mm; No. 3, 27 × 54 mm; and No. 4, 57 × 76 mm) or (e.g., 5 × 7 in, 5 × 12 in, and 8 × 10 in) used to produce radiographic images.
radiographic film storage methods,
n an appropriate method of safekeeping to maintain the integrity of the materials (e.g., the placement of items in regions that will prevent exposure to radiation, heat, vapors from chemical substances, and moisture), as well as the creation of a filing system that ensures the oldest product is used first.
n a vacuum tube containing electrodes that accelerate electrons and direct them to a metal anode where their impact produces a radiograph.
pertaining to or emanating from radiography.
radiographic contrast agent
see contrast medium.
radiographic film digestion test
a quantitative test for fecal trypsin in which a strip of x-ray film is incubated in an alkaline suspension of feces. Clearing of the film's gel indicates the prescence of trypsin. Used in the diagnosis of exocrine pancreatic insufficiency.
relates to the loss of clarity of the radiographic image as the subject moves further away from the film.
translation of the radiographic image into an explanation of the pathology underlying the abnormalities that are observed.
