N1 - Funding Information:
Of the several thoracic inhomogeneities the high conductivity intracavitary blood is considered to be most influential, and its effect best understood. In order to analyze this effect, Brody 1 used an idealized model in which the intracavitary blood mass was represented by a perfectly conducting sphere immersed in an infinite homogeneous medium (the surrounding tissues of the thorax). The effect of this perfectly conducting sphere on a dipole source located in the outer tissue is determined by utilizing image theory. 2 From the Department of Biomedical Engineering, Case Western Reserve University, Cleveland, Ohio. *Graduate student tProfessor of Biomedical Engineering Supported by N.I.H.

N2 - The effect of a perfectly conducting sphere simulating the intracavitary blood mass on a dipole source located at the interface with the outer tissue (myocardium) is studied, utilizing image theory. The resulting enhancement factor is found to be a function of the field point location and is not a constant, as previously reported by Brody and by Rush and Nelson.
