  Radon Transformation is generally used to construct optical image (like CT
image) from the projection data in biomedical imaging. In this paper, the
concept of Radon Transformation is implemented to reconstruct Electrical
Impedance Topographic Image (conductivity or resistivity distribution) of a
circular subject. A parallel resistance model of a subject is proposed for
Electrical Impedance Topography(EIT) or Magnetic Induction Tomography(MIT). A
circular subject with embedded circular objects is segmented into equal width
slices from different angles. For each angle, Conductance and Conductivity of
each slice is calculated and stored in an array. A back projection method is
used to generate a two-dimensional image from one-dimensional projections. As a
back projection method, Inverse Radon Transformation is applied on the
calculated conductance and conductivity to reconstruct two dimensional images.
These images are compared to the target image. In the time of image
reconstruction, different filters are used and these images are compared with
each other and target image.
