Liu Y, Maruvada S
J Acoust Soc Am
. 2022 Jun;
151(5):3043.
PMID: 35649924
A polyurethane-based tissue mimicking material (TMM) and blood mimicking material (BMM) for the acoustic and thermal characterization of high intensity therapeutic ultrasound (HITU) devices has been developed. Urethane powder and...

J Magn Reson Imaging
. 2021 May;
54(4):1119-1125.
PMID: 33942934
Background: Auditory and non-auditory safety concerns associated with the appreciable sound levels inherent to magnetic resonance imaging (MRI) procedures exist for neonates. However, current gaps in knowledge preclude making an...

Phys Med Biol
. 2018 Dec;
63(24):245008.
PMID: 30523987
A well-characterized ultrasound tissue-mimicking material (TMM) can be important in determining the acoustic output and temperature rise from high intensity therapeutic ultrasound (HITU) devices and also in validating computer simulation...

J Acoust Soc Am
. 2018 Jul;
143(6):3365.
PMID: 29960483
Time delay spectrometry (TDS) is extended for broadband characterization of plastics (low-density polyethylene, LDPE) and tissue-mimicking material (TMM). The results suggest that TDS and the conventional broadband pulse method give...

Int J Hyperthermia
. 2016 Apr;
32(3):239-43.
PMID: 27099078
Purpose The purpose of this study was to (1) develop a novel tissue-mimicking thermochromic (TMTC) phantom that permanently changes colour from white to magenta upon heating above ablative temperatures, and...

J Acoust Soc Am
. 2015 Apr;
137(4):1704-13.
PMID: 25920823
For high intensity therapeutic ultrasound (HITU) devices, pre-clinical testing can include measurement of power, pressure/intensity and temperature distribution, acoustic and thermal simulations, and assessment of targeting accuracy and treatment monitoring....

Wear K, Liu Y, Gammell P, Maruvada S, Harris G
IEEE Trans Ultrason Ferroelectr Freq Control
. 2015 Jan;
62(1):152-64.
PMID: 25585399
Nonlinear acoustic signals contain significant energy at many harmonic frequencies. For many applications, the sensitivity (frequency response) of a hydrophone will not be uniform over such a broad spectrum. In...

Wear K, Gammell P, Maruvada S, Liu Y, Harris G
IEEE Trans Ultrason Ferroelectr Freq Control
. 2014 Jan;
61(1):62-75.
PMID: 24402896
The traditional method for calculating acoustic pressure amplitude is to divide a hydrophone output voltage measurement by the hydrophone sensitivity at the acoustic working frequency, but this approach neglects frequency...

Cardiovasc Ultrasound
. 2012 Jul;
10:29.
PMID: 22805356
Background: Ultrasound (US) imaging can be enhanced using gas-filled microbubble contrast agents. Strong echo signals are induced at the tissue-gas interface following microbubble collapse. Applications include assessment of ventricular function...
