Evaluation of MRI-based Polymer Gel Dosimetry for Measurement of CT Dose Index (CTDI) on 64 slices CT Scanners
Introduction: Computed tomography (CT) has numerous applications in clinical procedures but its main problem is its high radiation dose to the patients compared to other imaging modalities using x-ray. CT delivers approximately high doses to the nearby tissues due to the scattering effect, fan beam (beam divergence) and limited collimator efficiency. The radiation dose from multi-slice scanners...
متن کاملoving Beam Helical CT Scanning
Images generated with helical scanning are degraded by partial volume artifacts caused by an increased slice thickness when compared to conventional computed tomography (CT) scanning. The slice thickness for a helical scan is proportional to the sum of the thickness of the fan of radiation and the distance the patient moves during data acquisition. We present a method called moving beam helical...
متن کاملCT dose reduction applications: available tools on the latest generation of CT scanners.
Increasing concerns about radiation dose have led CT manufacturers to further develop radiation dose reduction tools in the latest generation of CT scanners. These tools include automated tube current modulation, automated tube potential selection, and iterative reconstruction. This review details the principles underlying each of these 3 dose reduction utilities and their different permutation...
متن کاملCT radiation dose awareness among paediatricians
BACKGROUND The radiation dose delivered from computed tomography (CT) scanning and the risks associated with ionising radiation are major concerns in paediatric imaging. Compared to adults, children have increased organ sensitivity and a longer expected lifetime in which cancer may develop. Therefore, it is important to investigate the awareness of paediatricians (referring physicians) regardin...
متن کاملDesigning CT scanning rooms and estimating patient and personnel absorbed dose using code (MCNPX 2.6)
One of the most widely used diagnostic devices in medical imaging is computed tomography scanning with the use of X-ray ionization. After years of using this tool in the diagnosis and treatment, external doses of these beams can pose a risk of secondary cancer, which is significant in terms of radiation safety and protection. In this paper, using the Monte Carlo code MCNPX2.6 performed over thr...
