Abstract :
An investigation is conducted of the possibility of reconstructing images of current dipoles in a volume conductor from data obtained by the magnetoacoustic technique. A modified form of the algebraic reconstruction technique (ART) is used. Reconstruction results of simulated data show that it is possible to find the location, relative magnitude, and orientation of the dipoles with reasonable accuracy for simple dipole configurations.<>
