title: Tube potential and CT radiation dose optimization.
abstract: OBJECTIVE
  This article describes tube potential and its effect on image quality and radiation dose for CT in different body regions and clinical indications.
  
  
  CONCLUSIONS
  Tube potential is an important scanning parameter for radiation dose optimization. Reduction of tube potential results in increased image contrast of iodine-enhanced CT as well as increased image noise.
