Thrombolysis using multi-frequency high intensity focused ultrasound at MHz range: an in vitro study

PHYSICS IN MEDICINE AND BIOLOGY, 60(18), 7403–7418.

By: D. Suo n, S. Guo n, W. Lin *, X. Jiang n  & Y. Jing n

Contributors: D. Suo n, S. Guo n, W. Lin *, X. Jiang n  & Y. Jing n

author keywords: thrombolysis; multi-frequency HIFU; ultrasound
MeSH headings : Animals; Cattle; High-Intensity Focused Ultrasound Ablation / instrumentation; High-Intensity Focused Ultrasound Ablation / methods; In Vitro Techniques; Mechanical Thrombolysis / methods; Stroke / diagnostic imaging; Stroke / therapy; Thrombolytic Therapy; Ultrasonography
TL;DR: Multi-frequency acoustic waves at MHz range were introduced as HIFU excitations to reduce the required power for treatment as well as the treatment time and it was found that dual-frequency thrombolysis efficiency was statistically better than single-frequency under the same acoustic power and excitation condition.

2014 article

Thrombolysis enhanced by dual-frequency high-intensity focused ultrasound

2014 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IUS), pp. 2173–2176.

By: S. Guo n, D. Suo n, Y. Jing n, X. Jiang n , J. Frank*, W. Lin*, Ieee

Contributors: S. Guo n, D. Suo n, Y. Jing n, X. Jiang n , J. Frank*, W. Lin*, Ieee

author keywords: dual-frequency ultrasound; thrombolysis; cavitation; high-intensity focused ultrasound (HIFU)
TL;DR: It was found that dual-frequency results in more efficient thrombolysis, with the aim to reduce the acoustic power required to achieve the same lysis rate as single-frequency ultrasound. (via Semantic Scholar)

Temperature Rise in Tissue Ablation Using Multi-Frequency Ultrasound

IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 60(8), 1699–1707.

By: S. Guo n, Y. Jing n & X. Jiang n 

Contributors: S. Guo n, Y. Jing n & X. Jiang n 

MeSH headings : Ablation Techniques / methods; Animals; Body Temperature / physiology; Body Temperature / radiation effects; Breast / physiopathology; Breast / radiation effects; Breast / surgery; Chickens; Dose-Response Relationship, Radiation; High-Energy Shock Waves; High-Intensity Focused Ultrasound Ablation / methods; Radiation Dosage
TL;DR: It is believed that the more effective tissue ablation using multi-frequency ultrasound is likely attributed to the enhanced cavitation, a promising result for HIFU applications. (via Semantic Scholar)

2011 conference paper

Multi-frequency focused ultrasound for tissue ablation

Proceedings of the ASME International Mechanical Engineering Congress and Exposition, vol 2, 665–670.

By: S. Bakshi n, S. Guo n & X. Jiang n 

TL;DR: It was found that multi-frequency tissue ablation gives a higher maximum temperature accompanied by a faster rise, and a larger ablation lesion volume, compared with single frequency ablation, under the same input conditions of electrical power, exposure time and depth of focus.
