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.

Tissue engineering a fetal membrane [PDF]

, 2011
The aim of this study was to construct an artificial fetal membrane (FM) by combination of human amniotic epithelial stem cells (hAESCs) and a mechanically enhanced collagen scaffold containing encapsulated human amniotic stromal fibroblasts (hASFs ...

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.

Impedance of tissue-mimicking phantom material under compression [PDF]

Journal of Electrical Bioimpedance, 2013
Abstract The bioimpedance of tissues under compression is a field in need of study. While biological tissues can become compressed in a myriad of ways, very few experiments have been conducted to describe the relationship between the passive electrical properties of a material (impedance/admittance) and its underlying mechanical ...

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.

Freeze-drying platforms design for batch fabrication of Haversian system mimicking scaffolds with enhanced osteogenesis

Frontiers in Bioengineering and Biotechnology, 2022
The Haversian system is one of the most important pathways to repair bone defects, and it is the basic guarantee for the repair of bone defects, which means that the formation of the Haversian system indicates repairing of the defects. The integration of

Cylindrical illumination with angular coupling for whole-prostate photoacoustic tomography [PDF]

, 2019
Current diagnosis of prostate cancer relies on histological analysis of tissue samples acquired by biopsy, which could benefit from real-time identification of suspicious lesions.

A brief review for common doppler ultrasound flow phantoms

Journal of Medical Ultrasound, 2020
In this review, the flow phantoms and the wall-less flow phantoms with recognized acoustic features (attenuation and speed of sound), interior properties, and dimensions of tissue were prepared, calibrated, and characterized by Doppler ultrasound (US ...

Myocardial Architecture and Patient Variability in Clinical Patterns of Atrial Fibrillation [PDF]

, 2016
Atrial fibrillation (AF) increases the risk of stroke by a factor of four to five and is the most common abnormal heart rhythm. The progression of AF with age, from short self-terminating episodes to persistence, varies between individuals and is poorly ...

Poro-viscoelastic material parameter identification of brain tissue-mimicking hydrogels

Frontiers in Bioengineering and Biotechnology, 2023
Understanding and characterizing the mechanical and structural properties of brain tissue is essential for developing and calibrating reliable material models. Based on the Theory of Porous Media, a novel nonlinear poro-viscoelastic computational model was recently proposed to describe the mechanical response of the tissue under different loading ...
