| 内容記述 | The aim of this study is to estimate tube current modulation (TCM) profiles in paediatric computed tomography (CT) exami-nations with a TCM scheme (Volume-EC) and evaluate the estimation accuracy of TCM profiles. Another aim is to validateorgan doses calculated using Monte Carlo-based CT dosimetry software and estimated TCM profiles by comparing themwith those measured using 5-year-old and 10-year-old anthropomorphic phantoms and radio-photoluminescence glass dose-meters. Dose calculations were performed by inputting detailed descriptions of a CT scanner, scan parameters and CT imagesof the phantoms into the software. Organ doses were evaluated from the calculated dose distribution images. Average relativedifferences (RDs) between the estimated and actual TCM profiles ranged from−3.6 to 5.6%. RDs between the calculatedand measured organ doses ranged from−4.2 to 13.0% and−18.1 to 4.9% for 5-year-old and 10-year-old phantoms, respect-ively. These results validate dose calculations for paediatric CT scans using TCM. | |||||
