State and Civil Society in Central America,the performance of the ESM is analyzed for experimental data. Images are obtained for the case of a single source and seven (7) detector locations, an unusually limited number of source/detector pairs. These images are verified by numerical simulation. A new approach to data fitting (at the detectors) is introduced.

https://doi.org/10.1007/978-3-030-05438-0cuss alternative photon transport models and measurement schemes. We develop the inverse problem as the optimisation of an objective functions and develop three classes of algorithms fors its solution: Newton methods, linearised methods, and gradient methods. We concentrate on the use numerical meth

Football Research in an Enlarged Europee the body. The gamma rays are attenuated and scattered in complicated ways before they emerge from the body, and it is essential to have a good theoretical description of these processes before attempting the inverse problem. In this paper we make use of the Boltzmann transport equation to describe

International Political Economy Seriesdetect the presence of cancer by microwave imagining. In this paper we survey recent results we have obtained on the use of microwaves to detect leukemia in the bone marrow of the leg that suggest that this is possible. Our emphasis in this paper is on the mathematical problems that arise in this in

Ralph da Costa Nunez Ph.D.,Matthew Adamsivered dose can be approximated by the dual attenuated x-ray transform of the filtered beam profile function. The number of intensity-modulated beams required for dose conformation to a tumor is derived. The sampling requirement is at most (2π.... + 5/2) beams for a 2D tomotherapy geometry, where ..
