TL;DR: The physical processes underlying tissue mechanical response based on static and dynamic displacement methods and the assumptions commonly used to interpret displacement and strain measurements in terms of tissue elasticity for static OCE and propagating wave modes in dynamic OCE are described.

TL;DR: A fundamentally new approach to dynamic elastography using non-contact mechanical stimulation of soft media with precise spatial and temporal shaping is presented, called acoustic micro-tapping (AμT) because it employs focused, air-coupled ultrasound to induce significant mechanical displacement at the boundary of a soft material using reflection-based radiation force.

TL;DR: A signal filtering algorithm for OA image contrast enhancement has been proposed following a numerical approach to characterize the following parameters of an OA imaging system: resolution, maximum depth at which the tumor can be detected, and image contrast.

TL;DR: This technique was used for measuring of plane residual stress in welds and for in-depth testing of subsurface residual stresses in metals and the results are in good agreement with the laser ultrasonic method.

TL;DR: An integrated PA/US (PAUS) imaging system is presented operating at frame rates >30 Hz, and real-time (30 Hz frame rate) imaging of an 18-gauge needle inserted into a piece of chicken breast with subsequent delivery of an absorptive agent at more than 1-cm depth to mimic PAUS guidance of an interventional procedure is demonstrated.
