| Summary: | The long-term goal of this project is to develop Electrical Impedance Tomography (EIT) to improve the diagnosis of breast cancer. Electrical Impedance Imaging is the technology for making images of the electrical properties of the interior of a body from measurements of voltage and current made at electrodes applied to the body's surface. When these measurements are made across a wide spectrum of frequencies, the term "impedance spectroscopy" is used. EIT offers promise as a diagnostic adjuvant in breast cancer, since several investigators have reported clear distinctions between carcinoma, benign lesions and normal tissues in freshly-obtained mastectomy tissue samples. We have designed, built, tested and applied an EIT system (ACT4) to perform regional impedance spectroscopy on breasts simultaneously and in-register with 3-D mammograms. This poster reports preliminary regional spectral findings, and relates them to the pathology found at biopsy of those regions.
