PPT-Chest X-rays

Basic to Intermediate Interpretation Phillip Smith BA RRT Relative Densities The images seen on a chest radiograph result from the differences in densities of the materials in the body The hierarchy of relative densities from least dense dark on the radiograph to most dense light on the radiograph include.
