Reliability and validity of quantifying absolute muscle hardness using ultrasound elastography. [PDF]

PLoS ONE, 2012
Muscle hardness is a mechanical property that represents transverse muscle stiffness. A quantitative method that uses ultrasound elastography for quantifying absolute human muscle hardness has been previously devised; however, its reliability and ...

Thermal characteristics of non-biological vessel phantoms for treatment of varicose veins using high-intensity focused ultrasound. [PDF]

PLoS ONE, 2017
The ultrasonic treatment of varicose veins uses high-intensity focused ultrasound, in which a blood vessel is contracted by converting acoustic energy into thermal energy.

The Effect of Tissue-Mimicking Phantom Compressibility on Magnetic Hyperthermia

Nanomaterials, 2019
During hyperthermia, magnetite nanoparticles placed in an AC magnetic field become a source of heat. It has been shown that in fluid suspensions, magnetic particles move freely and generate heat easily.

Acoustical Characterization of Tissue - Mimicking Materials

2019 IEEE International Symposium on Medical Measurements and Applications (MeMeA), 2019
Ultrasonic devices are today widely used in hospitals for diagnosis and treatment purposes. Quality controls of ultrasonic devices used in the field of health must be performed on phantoms that simulate human tissue with similar acoustic properties to human tissue in terms of both safety and proximity to reality.

Mechanical behaviour of tissue mimicking breast phantom materials [PDF]

Biomedical Physics & Engineering Express, 2017
The mechanical properties of soft tissue have long been of interest in biomedical research and applications, and increasingly for breast cancer imaging. In this paper, the mechanical properties of three different materials used to emulate the mechanical behaviour of real breast tissue are measured: agar, gelatine, and silicone, to assess their ...

Tissue mimicking materials for imaging and therapy phantoms: a review [PDF]

Physics in Medicine & Biology, 2020
Tissue mimicking materials (TMMs), typically contained within phantoms, have been used for many decades in both imaging and therapeutic applications. This review investigates the specifications that are typically being used in development of the latest TMMs.

Tissue-mimicking materials assessment through ultrasound velocity measurement

SPIE Proceedings, 2003
Ultrasound characterization of biological tissues is facing the challenge of accurate sound velocity determination in soft materials of poorly controlled shape. In this work, an original method based on a through-transmission configuration is proposed to accurately determine the sound velocity cs in non-parallel bio-mimetic specimens.

T 1-mapping and dielectric properties evaluation of a 3D printable rubber-elastomeric polymer as tissue mimicking materials for MRI phantoms

Materials Research Express, 2020
In this study, a new series of 3D printable rubber-elastomeric polymer called PORO-LAY materials have been investigated regarding their suitability to serve as tissue mimicking materials (TMMs) for MRI phantoms.

Biometric Identity Based on Intra-Body Communication Channel Characteristics and Machine Learning

Sensors, 2020
In this paper, we propose and validate using the Intra-body communications channel as a biometric identity. Combining experimental measurements collected from five subjects and two multi-layer tissue mimicking materials’ phantoms, different machine
