[解]
Although this is adequate to achievenlocalization only to within a few centimeters, images reconstructed from datanacquired at this level of timing resolution have a higher signal-to-noise rationthan images reconstructed without time-of-flight information.
[補]
Time-of-flight PET:
This technique, which would allow the formation ofntomographic images without
mathematical reconstruction algorithms.
