Measurement of organ dose in chest CT examination using Monte Carlo simulation
Background: Exposure conditions in CT examinations are quite different from conventional Xray. In CT examination higher dose is given to patient in comparison with the dose in other diagnostic examinations. In order to calculate organ effective dose in chest CT, Monte Carlo simulation has been used in this study. Materials and Methods: The Impact survey data were used to determine the ...
متن کاملInvestigation into the effects of lead shielding for fetal dose reduction in CT pulmonary angiography.
This work aims to determine whether lead shielding can be used to decrease the radiation dose to the fetus during CT scans for the diagnosis of pulmonary embolism during early stage pregnancy. An anthropomorphic phantom was modified to contain a 15 cc ionization chamber at the site of the uterus to enable fetal dose to be measured. The effects of a range of scan parameters, positioning of lead ...

متن کاملDose Reduction Methods in Chest Computed Tomography
Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...
متن کاملRotation Time and Dose Reduction in Chest CT scans
Computed tomography is associated with exposing patients with high radiation doses. This study was conducted to evaluate the effect of reducing the rotation time to reduce the dose without compromising the image quality. Two types of CT scanners were involved in this study: a 4-slice and a 16-slice scanner. A significant reduction in CTD Ivol and DLP were observed with the 4-slice scanner, with...
