A method for constrained focusing or shaping of the Specific Absorption Rate deposition is proposed and discussed. The approach contemporarily takes advantage from multifre-quency applicators, which allow a better control of possible hot-spots, as well as from the proposed formulation, which allows to reduce the problem to a single or a series of Convex programming problems.

Abstract
A method for constrained focusing or shaping of the Specific Absorption Rate deposition is proposed and discussed. The approach contemporarily takes advantage from multifre-quency applicators, which allow a better control of possible hot-spots, as well as from the proposed formulation, which allows to reduce the problem to a single or a series of Convex programming problems. The approach is presented for the case of scalar fields but it can be extended to vector fields as well.File in questo prodotto:
