Size‐based protocol optimization using automatic tube current modulation and automatic kV selection in computed tomography
Size-based diagnostic reference ranges (DRRs) for contrast-enhanced pediatric abdominal computed tomography (CT) have been published in order to establish practical upper and lower limits of CTDI, DLP, and SSDE. Based on these DRRs, guidelines for establishing size-based SSDE target levels from the SSDE of a standard adult by applying a linear correction factor have been published and provide a...
متن کاملAttenuation-based automatic tube voltage selection and tube current modulation for dose reduction at contrast-enhanced liver CT.
PURPOSE To retrospectively determine whether the combined use of automatic tube voltage selection (ATVS) and automatic tube current modulation (ATCM) can effectively reduce radiation dose at contrast material-enhanced liver computed tomography (CT) while maintaining acceptable image quality compared with the use of ATCM alone. MATERIALS AND METHODS This study was approved by an institutional ...
متن کاملDevelop Optimal Tube Voltage and Tube Current Chart for Radiation Reduction in Pediatric CT Examinations
Many different techniques and researches on reducing the radiation dose for computed tomography (CT) examinations have been reported and developed in recent 30 years. However, most those technologies are not practical enough to enable them to be directly and easily implemented in clinic real applications because there is no directly relationship between those techniques and the actual CT scanni...
متن کاملEstimation of Absorbed and Effective Doses in Organs through Computed Tomography Examinations Using Automatic Exposure Control and Fixed Tube Current Techniques: A Phantom Case Study
Introduction: The study aimed to assess absorbed and effective doses in organs through computed tomography (CT) examinations using automatic exposure control (AEC) and fixed tube current (FTC) techniques. Material and Methods: Scanning parameters were obtained for routine adult CT examinations and used to estimate the organ absorbed and effec...
متن کاملAssessment of an organ‐based tube current modulation in thoracic computed tomography
Recently, specific computed tomography (CT) scanners have been equipped with organ-based tube current modulation (TCM) technology. It is possible that organ-based TCM will replace the conventional dose-reduction technique of reducing the effective milliampere-second. The aim of this study was to determine if organ-based TCM could reduce radiation exposure to the breasts without compromising the...
