Region-Based Partial Volume Correction Techniques for PET Imaging: Sinogram Implementation and Robustness
Figure 5
Plots of accuracy and precision of RC values using four PVC methods for the simulated sphere phantom (a), simulated brain phantom (b), and the physical sphere phantom (c). The error bars are standard deviations. The ideal values for RC are shown as green lines. RC: recovery coefficient, PVC: partial volume correction, GTM: geometric transfer matrix, sGTM: symmetric GTM, GTMo: GTM implemented in sinogram-space, sGTMo: sGTM implemented in sinogram-space, VOI: volume of interest, puta: putamen, caud: caudate nucleus, gry: grey matter, and wht: white matter.
