Heat capacity measurements of novel tissue-mimicking materials
2015 IEEE International Symposium on Medical Measurements and Applications (MeMeA) Proceedings, 2015In this work, innovative jelly tissue-mimicking materials (TMM) have been characterized measuring their specific heat capacity in the temperature range of (10 and 80) °C. These new specimens have improved acoustic characteristics and are promising for improving the efficacy of oncological treatments based on high intensity focused ultrasounds (HIFU ...

Experimental validation of predicted temperature rises in tissue-mimicking materials
Physics in Medicine and Biology, 1993Increasingly, it is recognised that diagnostic ultrasound is capable of causing temperature rises sufficient to damage tissue. Predictions of this heating are often based on simplified models of both the in vivo conditions and the relevant physical effects.

Differences of Ultrasound Propagation in Tissue and Tissue Mimicking Materials
1996The ultrasound images taken on homogeneous and isotropic tissue mimicking phantoms cannot be directly compared to the images taken from inhomogeneous and anisotropic tissues. For this purpose special comparison and measuring methods for the recognition and quantitative embracement of the propagation phenomena in inhomogeneous media were developed ...

Polyvinyl Alcohol Cryogel – Tissue Mimicking Material for Vascular Optical Elastography
Biomedical Optics, 2006We present a tissue-mimicking material for vascular optical elastography: polyvinyl alcohol (PVA) cryogel. Its optical and elastic properties are tunable and in the range that is relevant for biological tissue simulation. We report measurements of the elastic modulus, and of the optical properties, derived from quantitative analysis of optical ...

Tissue-mimicking phantom materials for narrowband and ultrawideband microwave applications
Physics in Medicine and Biology, 2005We propose and characterize oil-in-gelatin dispersions that approximate the dispersive dielectric properties of a variety of human soft tissues over the microwave frequency range from 500 MHz to 20 GHz. Different tissues are mimicked by selection of an appropriate concentration of oil.

Prospective tissue-mimicking materials for use in NMR imaging phantoms
Magnetic Resonance Imaging, 1982Water-based proteinaceous gels, which--with appropriate additives--are stable with time and possess a high melting point, have been used as base materials in ultrasonically tissue-mimicking materials. In the present work, versions of these gels having various concentrations of glycerol and graphite particles were studied regarding their NMR T1 and T2 ...

The Journal of the Acoustical Society of America, 1986
An apparatus and method of experimentation for measuring frequency-dependent angle scattering from in vitro tissue samples and tissue-like scattering media have been developed. Distinguishing features of this method are that data collection is rapid, data reduction is simple, and results, given in the form of the differential scattering cross section ...

Dielectric characterization study of liquid‐based materials for mimicking breast tissues
Microwave and Optical Technology Letters, 2011AbstractThe possibility of mimicking different types of breast tissues to realize experimental phantoms has been investigated by measuring the complex permittivity of polyethylene glycol mono phenyl ether (Triton X‐100) and distilled water solutions.

A reusable perfusion supporting tissue‐mimicking material for ultrasound hyperthermia phantoms
Medical Physics, 1990A new ultrasonically and thermodynamically tissue‐mimicking material is reported. The material is well suited for use in phantoms for testing ultrasound hyperthermia systems or related predictive models. Controlled convective heat transfer effects, mimicking to some extent perfusive heat transfer in tissues, can be instituted in the material with ...
