摘要: The threshold dosages for high-intensity focal lesion production were determined at 3 MHz in the cat liver exposure durations covering range 0.003-35 s. was found to parallel that brain over of 0.1 10 s, but be more than twice intensity level, approximately following relation IT/sup 0.5/=460 W-cm/sup 2//s/sup 2/, where I is peak and T duration. At shorter curve deviates from this relation, probably due a change transient cavitation mechanism damage. >
