intraobserver variabilities การใช้

• Often the results show a great deal of interobserver and intraobserver variability leading to much debate on the number of unique hues.
• These harmonic signals may arise differently at anatomic sites with similar impedances and thus lead to higher contrast resolution .  Along with higher contrast resolution it has an elevated signal-to-noise ratio and significantly reduced inter-and intraobserver variability compared with conventional US . Additionally it is possible to nearly eliminate ordinary US artifacts, i . e . side-lobe, near-field artifacts, reverberation artifacts.
