Question

What features of the high-transmission cellular grid allow these grids to maintain equal or less radiation dose to the patient compared with linear grids?

A. these grids use lead as strips and wood as the interspace material
B. they have copper as the strips and air as the interspace material
C. they use aluminum as the strips and air as the interspace material
D. they use wood as the strips and copper as the interspace material

Answer 1

High-transmission cellular grids maintain equal or less radiation dose to the patient by using copper strips and air as the interspace material.

Step-by-step explanation:

The features of high-transmission cellular grids that allow them to maintain equal or less radiation dose to the patient compared with linear grids are the use of copper as the strips and air as the interspace material (Option B). Copper is an effective shield against radiation, and air as the interspace material helps to minimize the range of radiation. The greater the density of electrons within a material, the smaller the range of radiation, which is why high-density materials like copper are used.
