Impact of Exposure Dose Reduction of Radiation Treatment Planning CT Using Low Tube Voltage Technique

Purpose: The aim of this study was to reduce the exposed dose of radiotherapy treatment planning computed tomography (CT) by using low tube voltage technique. Materials and Methods: We used tube voltages of 80 kV, 100 kV, and 120 kV, respectively. First, we evaluated exposure dose with CT dose index...
