Development of a free anthropomorphic voxel model of human body for wide-band computational electromagnetics dosimetry
To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولQuantitative estimates of tissue perfusion using simple initial upslope measures in DCE-CT and DCE-MRI
Mathematical models based on CT and MRI dynamic contrast-enhanced imaging data have become essential tools for the purpose of quantification of organ perfusion. Although several well-established mathematical models have been introduced for the analysis of dynamic contrast-enhanced data, the application of microsphere theory (also known as the upslope method USM) has attracted the attention of m...
متن کاملMAP-based kinetic analysis for voxel-by-voxel compartment model estimation: detailed imaging of the cerebral glucose metabolism using FDG.
We propose a novel algorithm for voxel-by-voxel compartment model analysis based on a maximum a posteriori (MAP) algorithm. Voxel-by-voxel compartment model analysis can derive functional images of living tissues, but it suffers from high noise statistics in voxel-based PET data and extended calculation times. We initially set up a feature space of the target radiopharmaceutical composed of a m...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
