Abstract :
Electrical impedance tomography (EIT) is an undeveloped medical imaging technology which permits regional assessment of the electrical properties of organs within the body based on measurements made from electrodes on the surface of the body. This method is about a thousand times cheaper, a thousand times smaller and requires no ionizing radiation compared with other medical imaging techniques. However, the resolution obtained from this technique is not enough good and the image reconstruction algorithms are not efficient. The present article provides an introduction and analysis on a new approach for EIT process as "block method in electrical impedance tomography". This method is used to enhance image resolution and also, to improve reconstruction algorithm.
