The Importance of Optimal Patient Positioning in CT
The aim of this presentation is to demonstrate the consequences of poor patient gantry positioning in CT, to both image quality and patient dose. I will investigate the effect of scanning off-isocentre versus optimal, central gantry positioning. I will discuss the options radiographers might meet to help get this right. I will also consider patient straightness and whether pursuing this is preferable to retrospective multiplane reconstruction straightening. At the end of the presentation, the audience will be able to fully understand the importance of patient positioning on a CT scanner, whilst improving acquisition workflow, and to leverage new technological advancements for correct patient positioning and acquisition to the fullest.
