Attenuation and speed of ultrasound in lung: dependence upon frequency and inflation.
نویسنده
چکیده
The dependence of the speed of sound and the attenuation coefficient upon exposure frequency, in the range of 1-5 MHz, and upon level of inflation, in the range of mass density 0.35-0.7 g/cm3, are reported. The speed of sound decreases linearly and the attenuation coefficient increases exponentially, for all levels of inflation studied.

The Ability of Ultrasonic Characterization to Extract the Dose Distribution of MAGIC-f Polymer Gel
Background & Aims: Today, different imaging techniques have been studied in the reading of radiationsensitive polymer gels dosage. Due to limitations of imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT), ultrasound techniques are proposed for dose-dependent parameter extraction. In this study, using MAGIC-f (methacrylic and ascorbic acid in gelatin initiat...

The aim of this study is to evaluate the effect of edible gelatin concentration as a polymerization agent on MAGIC-f polymer gel dose-response sensitivity irradiated by 1.25 MeV energy of cobalt-60. To investigate the dose-dependent polymerization, ultrasonic parameters of propagation speed of sound and broadband ultrasound attenuation coefficient were evaluated. To read-out of the radiation-in...
متن کاملMeasurement of the ultrasound attenuation and dispersion in whole human blood and its components from 0-70 MHz.
The ultrasound attenuation coefficient and dispersion from 0-70 MHz in whole human blood and its components (red blood cells and plasma) at 37°C is reported. The measurements are made using a fixed path substitution technique that exploits optical mechanisms for the generation and detection of ultrasound. This allows the measurements to cover a broad frequency range with a single source and rec...
متن کاملThe Energy Dependence of the Photoelectric Attenuation Coefficient of Substances
Introduction: The photoelectric attenuation coefficient of substances is known to depend upon the energy E of the photon and the effective atomic number of substances (Zeff) as (Zeffx/Ey). No definitive values about these indices x, y are given in the literature. The index x is said to lie between, 3.0 and 4.0, while for ‘y’ different values have been assigned, between 3.0 and 4.0. Method...
متن کاملAttenuation and speed of ultrasound in lung.
An earlier study established that the attenuation of z0 ultrasound in freshly excised dog lung at 1 MHz was unusually high, viz., more than an order of magnitude greater than air and greatly in excess of that exhibited by other soft tissues. • The opportunity to conduct such measurements as a function of frequency has since become available and the following is an initial reporting of this inve...
