Course Learning Goals
Students will:
- discuss practical considerations in setting standards for acceptable image quality;
- define contrast, density, detail, and distortion on radiographs;
- distinguish the relationships of factors that control and affect image densities and contrast;
- select beam limiting devices, compare and summarize grid types;
- select the most appropriate grid for a given clinical situation; and
- define exposure factor considerations involved in technique selection.
