Résumé
In Selective Internal Radiation Therapy (SIRT), The tool realigns the barycenter of SPECT projection images and shifts them to obtain a fine registration with the attenuation map. The tool was validated using a modified dynamic phantom with several breathing patterns. We compared the absorbed dose distributions derived from uncorrected(D In the phantom study, the agreement between D The proposed tool allowed the correction of
