Electrical impedance tomography (EIT) is a non-invasive technique for imaging the electrical conductivity and permittivity in the body by measuring the electrical potential on the surface. One of the EIT applications in the medical field is breast cancer detection. The study proposed a rectangular geometry EIT multi-frequency device based on the Finite Volume Method (FVM) reconstruction method. This device can be used to complement mammography images into dual EIT-mammography modalities. The EIT device built of DDS AD9850 as a programmable multi-frequency sinusoidal generator, AD620 as instrument amplifier, AD536 as an AC converter, and ADS1115 as an ADC 16 bit. These devices can scan at the maximum frequency of 100 kHz. The device has been tested with a phantom of distilled water and carrots in the center and on the sides. The reconstruction methods one step different frequency produces a rectangular geometric image with anomalies in the depth and at the surface clearly.
