Dose Reduction in CT by Anatomically Adapted Tube Current Modulation: First Patient Studies

  • Conference paper
Advances in CT IV

Abstract

The physical principles of dose reduction in computed tomography (CT) by anatomy-oriented attenuation-based tube current modulation, as discussed elsewhere in this volume (see Chap. 4), were tested in a first clinical patient study. Our aim was to reduce the dose applied in CT by current modulation and without a loss of image quality. Dose reduction was measured by the reduction of the mAs product, and image quality was assessed subjectively by experienced radiologists.
