TY - THES N2 - Proper use of computed tomography (CT) imaging systems depends heavily on accurate patient positioning. Patient misalignment with respect to scanner isocenter generates deleterious effects on both the quality of the resulting image and the radiation output of the CT scanner. Alignment errors produce pixel intensity inaccuracies and increases in noise which degrade the quality of the image. In terms of radiation dose, distorted approximations of patient size emanating from improper positioning result in misallocations of radiation output. The mission of this study is to increase patient alignment accuracy in an effort to optimize CT dose and image quality through an education initiative.
