Auditory Spatial Saliency and Its Effects on Perceptual Noisiness
Autor: Yuki Nakatani, Masayuki Watanabe, Naoko Yorozu
Publikováno v: IEEE Access, Vol 10, Pp 10160-10175 (2022)
Environmental noise affects significantly our health and quality of life. Simple techniques, such as A-weighted decibels, have been applied commonly to the real issues of environmental noise. More elaborate techniques, considering mechanisms in the c

Improved Detection of Lung Fluid With Standardized Acoustic Stimulation of the Chest
Autor: Adam Rao, Simon Chu, Neil Batlivala, Samuel Zetumer, Shuvo Roy
Publikováno v: IEEE Journal of Translational Engineering in Health and Medicine, Vol 6, Pp 1-7 (2018)
Accumulation of excess air and water in the lungs leads to breakdown of respiratory function and is a common cause of patient hospitalization. Compact and non-invasive methods to detect the changes in lung fluid accumulation can allow physicians to a

Analytical methods for evaluating reliability and validity of mobile audiometry tools
Autor: Mona Kelkar, Zhaoxun Hou, Gary C. Curhan, Sharon G. Curhan, Molin Wang
Publikováno v: J Acoust Soc Am
Statistical approaches that could be used as standardized methodology for evaluating reliability and validity of data obtained using remote audiometry are proposed. Using data from the Nurses' Health Study II ( n = 31), the approaches to evaluate the

Three-dimensional echo decorrelation monitoring of radiofrequency ablation in ex vivo bovine liver
Autor: E. Ghahramani Z, P. D. Grimm, K. J. Eary, M. P. Swearengen, E. G. Sunethra K. Dayavansha, T. D. Mast
Publikováno v: J Acoust Soc Am
Three-dimensional (3D) echo decorrelation imaging was investigated for monitoring radiofrequency ablation (RFA) in ex vivo bovine liver. RFA experiments ( N = 14) were imaged by 3D ultrasound using a matrix array, with in-phase and quadrature complex

Ultrasonic backscatter coefficient estimation in nonlinear regime using an in situ calibration target
Autor: Andres Coila, Michael L. Oelze
Publikováno v: J Acoust Soc Am
Tissue characterization based on the backscatter coefficient (BSC) can be degraded by acoustic nonlinearity. Often, this degradation is due to the method used for obtaining a reference spectrum, i.e., using a planar reference in water compared to a r

Numerical simulation of wave propagation through interfaces using the extended finite element method for magnetic resonance elastography
Autor: Quanshangze Du, Aline Bel-Brunon, Simon Auguste Lambert, Nahiène Hamila
Publikováno v: J Acoust Soc Am
Magnetic resonance elastography (MRE) is an elasticity imaging technique for quantitatively assessing the stiffness of human tissues. In MRE, finite element method (FEM) is widely used for modeling wave propagation and stiffness reconstruction. Howev

Identifying and overcoming limitations with in situ calibration beads for quantitative ultrasound
Autor: Jenna Cario, Andres Coila, Yuning Zhao, Rita J. Miller, Michael L. Oelze
Publikováno v: J Acoust Soc Am
Ensuring the consistency of spectral-based quantitative ultrasound estimates in vivo necessitates accounting for diffraction, system effects, and propagation losses encountered in the tissue. Accounting for diffraction and system effects is typically

Robust and durable aberrative and absorptive phantom for therapeutic ultrasound applications
Autor: Alex T, Peek, Gilles P L, Thomas, Daniel F, Leotta, Petr V, Yuldashev, Vera A, Khokhlova, Tatiana D, Khokhlova
Publikováno v: J Acoust Soc Am
Phase aberration induced by soft tissue inhomogeneities often complicates high-intensity focused ultrasound (HIFU) therapies by distorting the field and, previously, we designed and fabricated a bilayer gel phantom to reproducibly mimic that effect.
