Resumo: Abstract This paper presents a solution for sphere-shaped heterogeneities applied to the bioimpedance test. Such an approach has applicability for electrical impedance tomography, considering the impedance response for electrodes at the skin level, a healthy tissue composing a half-space, and a spherical anomaly representing a malignant or even benign tumor. The presented methodology consists of an inverse solution; however, it has high computational performance and can be later applied to an optimization procedure for generating medical images. The proposed formulation does not require a domain discretization and is validated in the paper using Finite Element Analysis.
