“…The lateral resolution is determined by the aperture of the transducer, which is on the order of millimeters. In this scheme, PA signal amplitudes and spectra, depth profiles, and B-mode images may provide useful information [27][28][29][30][31][32][33][34][35][36][37]. (2) PA computed tomography (PACT).…”

“…In addition, the defects and their depth in the graphite epoxy composites can also be determined by conducting a PA spectral and correlation analysis [29]. Podymova et al [33] demonstrated the measurement of phase velocities, which can be utilized to determine the local porosity of SiC-particle-reinforced siluminmatrix composites. The local Young's modulus of the composites can be determined by the pulsed PA method, and the effect of the porosity on the local Young's modulus was quantitatively evaluated [36].…”

Photoacoustic (PA) imaging has been widely used in biomedical research and preclinical studies during the past two decades. It has also been explored for nondestructive testing and evaluation (NDT/E) and for industrial applications. This paper describes the basic principles of PA technology for NDT/E and its applications in recent years. PA technology for NDT/E includes the use of a modulated continuous-wave laser and a pulsed laser for PA wave excitation, PA-generated ultrasonic waves, and all-optical PA wave excitation and detection. PA technology for NDT/E has demonstrated broad applications, including the imaging of railway cracks and defects, the imaging of Li metal batteries, the measurements of the porosity and Young’s modulus, the detection of defects and damage in silicon wafers, and a visualization of underdrawings in paintings.

“…Historically, the problems of laser photoacoustics have been the subject of studies by both individual scientists and scientific schools [1][2][3][4][5][6][7]. This interest is due to the fact that the effect of photostimulated generation of mechanical (acoustic) waves in radiation-exposed media is widely used for various applications.…”

“…Laser medicine occupies one of the central positions among these applications. Various areas are successfully developing here, such as high-resolution tomography [4,7], so-called 'cold' (low temperature or cavitation) laser microsurgery [1][2][3][4][5][6], and also optoacoustic control of medical treatment processes. This work is devoted to development of the physical fundamentals of a novel medical application of laser photoacoustics, namely, enhancement of the hydraulic permeability of biological tissues through their 'loosening' of sorts by cavitation microbubble fields.…”

Thermomechanical effect of pulse-periodic laser radiation on cartilaginous and eye tissues

et al. 2013

View full text Add to dashboard Cite

This paper is devoted to theoretical and experimental studies into the thermomechanical action of laser radiation on biological tissues. The thermal stresses and strains developing in biological tissues under the effect of pulse-periodic laser radiation are theoretically modeled for a wide range of laser pulse durations. The models constructed allow one to calculate the magnitude of pressures developing in cartilaginous and eye tissues exposed to laser radiation and predict the evolution of cavitation phenomena occurring therein. The calculation results agree well with experimental data on the growth of pressure and deformations, as well as the dynamics of formation of gas bubbles, in the laser-affected tissues. Experiments on the effect of laser radiation on the trabecular region of the eye in minipigs demonstrated that there existed optimal laser irradiation regimens causing a substantial increase in the hydraulic permeability of the radiation-exposed tissue, which can be used to develop a novel glaucoma treatment method.
