High-resolution ultrasound-modulated optical tomography in biological tissues.

We present a novel implementation of high-resolution ultrasound-modulated optical tomography that, based on optical contrast, can image several millimeters deep into soft biological tissues. A long-cavity confocal Fabry-Perot interferometer, which provides a large etendue and a short response time, was used to detect the ultrasound-modulated coherent light that traversed the scattering biologic...

Measurement of high frequency electrical transfer impedances from biological tissues

Introduction: Electrical impedance spectroscopy (EIS) is a non-invasive method for characterising human tissue. Because currents will pass either around or through cells depending on the frequency, EIS can be used to observe the structure and arrangement of cells. EIS has been used to identify precancerous changes in the oesophagus and cervix [1]. Many of the precancerous changes in tissue conc...

A high-frequency shear device for testing soft biological tissues.

Accurate mechanical property data obtained at large shear deformations and high frequencies are a fundamental component of realistic numerical simulations of soft tissue injury. Although many commercial systems exist for testing shear properties of viscoelastic materials with properties similar to soft biological tissue, none are capable of determining properties at high loading rates necessary...

Quantitative Assessment of First Annular Pulley and Adjacent Tissues Using High-Frequency Ultrasound

Due to a lack of appropriate image resolution, most ultrasound scanners are unable to sensitively discern the pulley tissues. To extensively investigate the properties of the A1 pulley system and the surrounding tissues for assessing trigger finger, a 30 MHz ultrasound system was implemented to perform in vitro experiments using the hypodermis, A1 pulley, and superficial digital flexor tendon (...

Quantification of Ultrasound Contrast Agents Using High Frequency Ultrasound

Ultrasound contrast agents (UCAs) are small microbubbles filled with gas. Because of their scattering properties, UCAs enhance the diagnostic capabilities of ultrasonic imaging. UCAs are associated with therapeutic or enhancing therapeutic applications of ultrasound and with possible adverse bioeffects. Quantification of the in vivo concentration of microbubbles is therefore essential to establ...
