ECVT (Electrical Capacitance Volume Tomography) is an imaging technique that utilizes the capacitance value of the volume-shaped object surrounded by a multi-sensor. Sensors which surround the object is to measure the value of electric capacitance is influenced by the permittivity distribution contained in the object which is then reconstructed with the appropriate algorithm to obtain the image using the software MATLAB R2008a. While making the object model of breast tumor tissue and the sensor is obtained through FEM or known by the Finite Element Method using the software COMSOL Multiphysics 3.4. Ill-posed problems arising in the reconstruction process, handled using methods ILBP or Landweiber equation. Testing breast cancer sensor based electrical capacitance is done on an object by using the human breast 24 electrodes placed around the object. From the experimental results can be shown that the image of the results of reconstructing the permittivity distribution has the same pattern with the distribution of permittivity on the object model and can diagnose the physical presence of symptoms in patients with breast cancer.
Key words: ECVT, MATLAB R2008a, FEM, ILBP, Breast Cancer, image Reconstruction.
