Figures
- FIGURE 1.
Theoretic average-based and maximum-based BRT curves (solid lines) and respective measured BRT values (symbols). Values within parentheses are smoothing levels used in image reconstruction.
- FIGURE 2.
Percentage differences between segmented and true volume (symbols) as function of signal level for small (A) and large sphere (B). Numbers within parentheses are sphere diameters in units of spatial resolution. Solid lines indicate zero percentage deviations from true volume. 95% CIs are represented by dashed lines.
- FIGURE 3.
Percentage differences between segmented and true volume (symbols) as function of SBR for small (A) and large sphere (B). Numbers within parentheses are sphere diameters in units of spatial resolution. Solid lines indicate zero percentage deviations from true volume. 95% CIs are represented by dashed lines.
- FIGURE 4.
Percentage differences between segmented and true volume (symbols) as function of prepared hemisphere AC ratio using avg-ITM (A) and max-ITM (B). Gray solid lines are obtained by fitting measured data points with sigmoidal function. Upper solid line indicates zero percentage deviation from true values when both hemispheres were filled with equal AC, whereas lower solid line is expected percentage deviation from total volume when only single hemisphere contained radioactivity. 95% CIs are represented by dashed lines.
- FIGURE 5.
18F-FDG PET/CT transverse views of abdominal tumor (left; A, C, and E) and 124I PET/MRT transverse views of thyroid tumor (right; B, D, and F). Red lines indicate tumor boundaries. (A color version of this figure is available as a supplemental file online at http://tech.snmjournals.org/.)
