A comparison of fixed tube current (FTC) and automatic tube current modulation (ATCM) CT methods for abdominal scanning : implications on radiation dose and image quality
… The aim of this thesis is to evaluate Fixed Tube Current (FTC) and Automatic Tube Current Modulation (ATCM) on image quality and radiation dose during abdominal CT examinations across a range of scanning parameters. MATERIALS AND METHODS: Using a Toshiba Aquilion 16 CT scanner (120 kVp, 0.5 …

Dosisreduktion in der Multidetektor-Computertomographie
… this work by phantom- and patient studies.1. The tube-current-modulation system "CareDose 4D" (Siemens Medical Solutions, Forchheim, Germany) enabled a reduction of effective dosage of 56,1% up to 70,1%, depending on the orientation of the scanogram used, while image noise was elevated in turn.2. …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
… as followings: LDCT, 40mAs with automatic tube current modulation (ATCM) and 100kVp (body mass index (BMI) <25, n=51) or 120kVp (BMI>25, n=18); SDCT, 180mAs with ATCM and 120kVp. Transverse, coronal, saggital images were reconstructed with 3-mm slice thickness without gap for investigators. …

Individuelle Anpassung des Röhrenstroms zur Dosisreduktion bei CT-Untersuchungen
In der vorliegenden Arbeit sollte untersucht werden, welcher individuelle Röhrenstrom für unterschiedliche anatomische Regionen (Schädel, Hals, Thorax und Abdomen) nötig ist um diagnostisch aussagekräftige CT-Aufnahmen zu erzeugen. In diese prospektive Studie wurden 262 erwachsene Patienten …
