How to solve inverse problem in electrical resistance tomography using optimization module?

Please login with a confirmed email address before reporting spam

The Electrical Resistance Tomography has been divided into two problems. The forward problem and the inverse problem. The forward problem consists of creating a virtual model of a phantom with a tumour like impurity and consisting of electrodes surrounding the phantom and we pass alternating current to the one electrode in each cycle and the voltage across all other electrodes is been calculated. This is done for all electrodes.

The inverse problem involves using these voltages and reconstructing the images of phantom so that the exact location of the impurity has to be located. How to solve the inverse problem using optimiation module in this technique using the obtained voltages from the forward problem?
