Structural and functional synergy for quantitative PET images

使用基于小波的分辨率恢复方法SFS-RR(结构和功能协同分辨率恢复)，我们已经证明了结构图像有效地恢复了大脑皮层区域的真实信号(Shidahara等人，2009)。在目前的工作中，我们评估了在纹状体区域多巴胺功能量化的情况下恢复策略的性能。事实证明，所提出的方法在恢复大脑微小结构的拉克洛必利PET图像方面是有效的，并且这种改进在模拟人群的解剖变异中是一致的。

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.
