| Research Abstract |
Using a wavelet-based resolution recovery method named SFS-RR (structural and functional synergy for resolution recovery), we have demonstrated that the structural image effectively recovers the true signal in cortical areas (Shidahara et al., 2009). In the current work, we evaluate the performance of the recovery strategy in the case of the quantification of dopaminegic function in striatal regions. The proposed methodology proved effective in the resolution recovery of small structures of brain [^<11>C]raclopride PET images and the improvement is consistent across the anatomical variability of a simulated population.
