Lincoln em spillman r. Overview an x ray is a quick painless test that produces images of the structures inside your body particularly your bones. Most x rays have a wavelength ranging from 10 picometres to 10 nanometres corresponding to frequencies in the range 30 petahertz to 30 exahertz 310 16 hz to 310 19 hz and energies in the range 124 ev to 124 kev. Body build in infants. Normal radiographic measurements of the shoulder are important in evaluation of the osseous relationships in plain film radiography. The passage of x rays through materials including biological tissue can be recorded.
Dense materials such as bone and metal show up as white on x rays. Studies of the hearts of normal children. Measurements of the trunk of the body should always be made in the same general position as for radiography because measurements may change significantly when the patient changes position. X ray beams pass through your body and they are absorbed in different amounts depending on the density of the material they pass through. X ray electromagnetic radiation of extremely short wavelength and high frequency with wavelengths ranging from about 10 8 to 10 12 metre.
