relationship among transmitted x-rays, photoelectrically absorbed x-rays, and compton scattered x-rays resulting in the x-ray image
scattering of very-low-energy x-rays with no loss of energy; also called coherent or Thompson scattering
quantity of matter per unit volume, usually specified in kilograms per cubic meter (kg/m3). Sometimes reported in grams per cubic centimeter (gm/cm3).
threshold energy required by a photon to undergo pair production
A high-atomic number material (for example, iodine and barium), or a low density, low-atomic number material (air) administered in liquid or gas form to improve the contrast resolution of an x-ray examination
X-ray ionization resulting in x-ray scattering
The reduction in x-ray beam intensity as a result of photoelectric absorption and compton scattering
Having a single energy. Characteristic x-rays are monoenergetic, and the effective x-ray energy of an x-ray beam is the monoenergetic equivalent of the actual beam.
electrons released in ionization as the result of photoelectric interaction and Compton scattering
an x-ray absorption interaction in which the x-ray is not scattered but totally absorbed. A photoelectron is then released from the atom.
