Abstract :
The application of linear reconstruction techniques, namely, the algebraic reconstruction technique (ART) and the simultaneous algebraic reconstruction technique (SART), to the reconstruction of the microwave attenuation coefficient distribution of 2D and 3D lossy dielectric objects is investigated. The reconstructed 2D and 3D images using both techniques are compared for noiseless data and for data with a finite signal-to-noise ratio. It shows that the ART generally produces better images. However, the SART has a less effect from the noise.
