stepwedge

[step′wej]

an aluminum device that, when exposed to x-rays, displays a range of exposure intensities on a radiograph. These exposure "steps" are analyzed to determine the speed characteristics of the radiographic film. Also called penetrometer.

stepwedge [step´wej]

a device used for comparing exposure intensities in photography or radiography; a series of tones from white to black (photography) or plates of increasing thickness (radiography) are placed between the energy sources and the film and differences in exposure are noted.

stepwedge,

n an aluminum device that, when exposed to roentgen rays, displays a range of exposure intensities on a radiograph. These “steps” are analyzed to determine the speed characteristics of the radiographic film. See also penetrometer.

stepwedge

a block of aluminum shaped like a series of steps. Used to test the characteristics of the x-ray beam, film, filters and to standardize exposure factors.
