Title:
マイクロバブル強化超音波処置における超音波周波数およびマイクロバブルサイズの最適化
Document Type and Number:
Japanese Patent JP7232204
Kind Code:
B2
Abstract:
Various approaches for enhancing treatment of target tissue using a source of focused ultrasound while limiting damage to non-target tissue include selecting a frequency of ultrasound waves transmitted from the source of focused ultrasound for generating a focus in the target tissue; providing microbubbles having the first size distribution such that at least 50% of the microbubbles have a radius smaller than a critical radius corresponding to a resonance frequency matching the selected frequency of ultrasound waves; and applying the ultrasound waves at the selected frequency to treat the target tissue.
