Reconstructing a Vector Current Distribution from its Magnetic Field Using Linear Estimation Theory

Abstract

Several methods currently exist for exploring the three-dimensional structure of the organs of the human body. They include x-ray computed tomography (CT),1 magnetic resonance imaging (MRI),2 and emission computed tomography (ECT).3,4 These techniques provide spatial information about an organ's attenuation coefficient, proton density, or the ability of the organ to take up a radioactive pharmaceutical, respectively.
