2015 journal article
Thrombolysis using multi-frequency high intensity focused ultrasound at MHz range: an in vitro study
PHYSICS IN MEDICINE AND BIOLOGY, 60(18), 7403–7418.
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.
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.

Design, Fabrication, and Characterization of a Single-Aperture 1.5-MHz/3-MHz Dual-Frequency HIFU Transducer
IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 60(7), 1519–1529.
MeSH headings : Animals; Equipment Design; High-Intensity Focused Ultrasound Ablation / instrumentation; Meat; Models, Biological; Swine; Transducers
TL;DR:
Tissue ablation tests demonstrated that higher temperature rise can be achieved with dual-frequency ultrasound than with single-frequency ablation at the same acoustic power.

2013 journal article
Temperature Rise in Tissue Ablation Using Multi-Frequency Ultrasound
IEEE TRANSACTIONS ON ULTRASONICS FERROELECTRICS AND FREQUENCY CONTROL, 60(8), 1699–1707.
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.

2012 conference paper
Multi-frequency focused ultrasound for tissue ablation
Proceedings of the ASME International Mechanical Engineering Congress and Exposition, vol 2, 665–670.
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.
