Magnetic Susceptibility Tomography with Nonuniform Field

Abstract

Imaging systems that generate slice views of the body are called tomographicscanners. Several modalities of scanners that generate such crosssectional images have been developed for biomedical applications,such as Xray tomography, PET and MRI. Magnetic susceptibility tomography(MST) may be a new tool for visualizing the interior of the body,Previous works have shown that it is possible to reconstruct a 4x4x4susceptibility distribution from the perturbation produced undera uniform field. In this paper the solution to the inverse problemis addressed in the framework of reconstruction from projections.A nonuniform field is considered together with uniform field.
