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 ...

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 ...

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 ...
