CT patient positioning [Centering Rational]
Check out the BEST NEW RADIOGRAPHY BOOK https://tinyurl.com/RadPhysicsMastery , to help one your ARRT registry. CT positioning is less sensitive than x-ray for image quality due to the power of 3D reconstruction. However one important topic is centering the patient within the scan field of view. The bowtie filters used on CT scanners attenuate outer rays more, and when the patient is not centered one region of the volume will get extra dose and the other region will have higher noise.
