In other to achieve higher levels of X-ray attenuation than observed for biological tissue,elements of higher atomic number(Z) are incorporated into the contrast agent molecule. Lithium iodide (LiI) was among the first water-soluble imaging agents. Compare mass attenuation coefficients for soft tissues and for lithium iodide

Identify the fundamental mechanisms for x-ray absorption and the relationship for the attenuation of a narrow beam of photons. Define the linear attenuation coefficient and half value thickness. For a typical steel identify how many half-layer values are needed to reduce transmitted energy to 3.1%. Select an example of a steel and determine this samples physical thickness needed to reduce radiation to 3.1 % at 100 keV. [Be sure to identify the steel used including the details of composition and...
