Evaluation of Computed Tomography X-Ray Beam Dose Profiles

Computed tomography (CT) is an imaging procedure that uses X-rays to create detailed pictures, or cross-section scans, of areas inside the body. Benefits of the CT have been proven over the past decades, but they come with a price high radiation doses to patients. Understanding how doses depend on technical parameters is a necessary step towards an optimized imaging procedure. Aim of this study was to assess the air kerma distribution and size of the X-ray beam of a conventional computed tomography scanner.
