The iterative Time Domain Inversion tomographic algorithm (TDI) proposed by Chalmers University of Technology is compared in terms of image quality to the UWB Magnitude Combined tomographic algorithm (MC-UWB) proposed by the Universitat Politècnica de Catalunya (UPC). The first is able to provide quantitative permittivity images of the object under test, while the second provides quantitative images, being its major strength the short reconstruction time (real time) and robustness. The comparison between the algorithms will be performed based on experimental measurements acquired with two tomographic setups, available at both universities. The Chalmers setup provides a short acquisition time but a narrow band behavior due to the monopole antennas, while the UPC setup is slower but uses broadband antennas.
