Quantitative Photo-Acoustic Imaging of Small Absorbers∗

چکیده
In photo-acoustic imaging, energy absorption causes thermo-elastic expansion of optical absorbers, which in turn leads to propagation of a pressure wave. Recently, we have developed an efficient method for locating small absorbing regions inside a bounded domain from boundary measurements of the induced pressure wave and reconstructing the absorbed density. However, it is the absorption coefficient, not the absorbed energy, that is a fundamental physiological parameter. In this paper, we propose two methods for reconstructing the normalized optical absorption coefficient of a small absorber from the absorbed density. AMS subject classifications. 31B20, 35B37,35L05

Mathematical Modeling in Photoacoustic Imaging of Small Absorbers
This paper is devoted to mathematical modelling in photo-acoustic imaging of small absorbers. We propose a new method for reconstructing small absorbing regions inside a bounded domain from boundary measurements of the induced acoustic signal. We also show the focusing property of the backpropagated acoustic signal. Indeed, we provide two different methods for locating a targeted optical absorb...
متن کاملEffect of porosity on the characteristics of underwater acoustic sound absorbers using theoretical models
Porous materials have good acoustic damping characteristics over a wide frequency range. As for sound waves, many small-scale pores in the coating materials can convert underwater-coating to rough surfaces. The main property of porous absorbents is their resistance against incident sound wave that leads to damping effect. From a physical point of view, damping occurs due to friction between flu...
متن کاملInvestigation on acoustic behavior of acoustic porous absorbers to absorb sound energy and transmission loss index
In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.
متن کاملInvestigation of acoustic properties of silica coated gold nanoparticle as contrast agent for Ultrasonography
Interoduction: Ultrasound images have often low contrast due to small differences in acoustic impedance between different tissues. Air or gas microbubbles that surrounded by membrane are most of the contrast agents in ultrasound imaging. Problems such as instability in sound pressure and inability in penetrating from the blood vessel into body tissues limited the use of microbubbles into the in...
متن کاملContrast-enhanced magneto-photo-acoustic imaging in vivo using dual-contrast nanoparticles☆
By mapping the distribution of targeted plasmonic nanoparticles (NPs), photoacoustic (PA) imaging offers the potential to detect the pathologies in the early stages. However, optical absorption of the endogenous chromophores in the background tissue significantly reduces the contrast resolution of photoacoustic imaging. Previously, we introduced MPA imaging - a synergistic combination of magnet...
