In urban centres of industrialising countries, the majority of houses are served by on-site sanitation systems such as septic tanks and unsewered toilets. The faecal sludges (FS) collected from these systems are usually discharged untreated into the urban and peri-urban environment, posing great risks to water resources and to public health. Contrary to wastewater management, the development of...
متن کاملTBI lung dose comparisons using bilateral and anteroposterior delivery techniques and tissue density corrections
This study compares lung dose distributions for two common techniques of total body photon irradiation (TBI) at extended source-to-surface distance calculated with, and without, tissue density correction (TDC). Lung dose correction factors as a function of lateral thorax separation are approximated for bilateral opposed TBI (supine), similar to those published for anteroposterior-posteroanterio...
متن کاملDose calculations accuracy of TiGRT treatment planning system for small IMRT beamlets in heterogeneous lung phantom
Background: Accurate dose calculations in small beamlets and lung material have been a great challenge for most of treatment planning systems (TPS). In the current study, the dose calculation accuracy of TiGRT TPS was evaluated for small beamlets in water and lung phantom by comparison to Monte Carlo (MC) calculations. Materials and Methods: The head of Siemens Oncor-impression linac...
