Effect of Profile Width on Spatial Resolution
| Direction | Profile width = 1 mm | Profile width = 2 × FWHM | ||||
|---|---|---|---|---|---|---|
| FWHM (mm) | FWTM (mm) | FWHM (mm) | FWTM (mm) | |||
| Y | 4.4 ± 0.1 | 9.1 ± 0.1 | 4.9 ± 0.3 | 12.2 ± 0.5 | ||
| X | 4.6 ± 0.2 | 11.8 ± 2.0 | 5.4 ± 0.1 | 11.5 ± 0.7 | ||
| Average (X, Y) | 4.5 ± 0.2 | 10.5 ± 2.0 | 5.2 ± 0.4 | 11.9 ± 0.7 | ||
Data were taken on ADAC UGM C-PET scanner. Values are for x = y = 0 cm, averaged over Z = 0 and Z = ¼ axial FOV. Overall average is over X and Y values for 2 axial positions (4 numbers).
