    ¡¾Abstract¡¿ AIM: To reconstruct the electrical impedance parameter tomogram of tissues. METHODS: Backprojection was utilized to reconstruct the electrical impedance tomogram at every driving frequency before the Coleª²Cole model of bioelectrical spectroscopy was analyzed and computed in complex plane. Then, image reconstruction was performed. RESULTS: The image of the dispersion parameter of Coleª²Cole model was reconstructed using the data acquired from a 32ª²electrode phantom. CONCLUSION: The reconstructed image of the scheme is acceptable and the method used in this study can yield better images after some optimization. ......
