Segmentation of Striatal Brain Structures from High Resolution PET Images

Figure 3

HRRT phantom. (a), (b), and (c) represent the transaxial, sagittal, and coronal views of the HRRT phantom with the ideal noise level, while (d), (e), and (f) represent to the same phantom with the more realistic noise level. Figures 3(g) to 3(l) are the zoomed (400%) to the striata in the images presented in (a) to (f).
