Viscoelasticity imaging of biological tissues with phase-resolved photoacoustic measurement.
A method for noninvasive viscoelasticity imaging of biological tissues using phase-resolved photoacoustic measurement is presented. We deduced the process of photoacoustic effect on the basis of thermal viscoelasticity theory, and established the relationship between the photoacoustic phase delay and the viscosity-elasticity ratio for soft solids. Agar phantoms with different densities and diff...
متن کاملOptical characterization and imaging of biological tissues
The biological tissues exhibit their distinct optical characteristics. Their point-to-point compositional variation could either be determined by the optical parameters or reconstruction of the reflectance or tomographic images. The optical parameters, absorption and reduced scattering coefficients of goat tissues and human post-mastectomy breast specimen are determined by matching of their ref...
متن کاملMechanical Properties of Biological Tissues
The material response discussed in the previous chapters was limited to the response of elastic materials, in particular to linearly elastic materials. Most metals, for example, exhibit linearly elastic behavior when they are subjected to relatively low stresses at room temperature. They undergo plastic deformations at high stress levels. For an elastic material, the relationship between stress...
متن کاملMultiprobe laser reflectometry in imaging and characterization of biological tissues.
Laser backscattered radiation from human forearm and foot were measured by multi-probe reflectometer, which consisted of one input probe and three output probes placed at distances of 2, 4 and 6 mm from the input probe. The normalized backscattered intensity (NBI) signals from the tissue surface, measured by the output probes, after digitization, were used to reconstruct the reflectance images ...
متن کاملThe advantage of using a diode laser instead of a Q-switched laser in photoacoustic imaging of tissues
Photoacoustic (PA) imaging of biological tissues using laser diodes instead of conventional Q switched pulsed systems provides an attractive alternative for biomedical applications. However, the relatively low energy of laser diodes operating in the pulsed regime, results in generation of very weak acoustic waves, and low signal-to-noise ratio (SNR) of the detected signals. This problem can be ...
