Shear wave elasticity imaging: a new ultrasonic technology of medical diagnostics.

Ultrasonic micro-elastography on assessing corneal biomechanics

The cornea, the window of the eye, provides approximately two-thirds of the total refractive power. The unique set of corneal biomechanical properties determined by its complex structure plays an important role in maintaining corneal function and human vision system [1]. Many factors, like ageing, trauma, diseases or clinical refractive surgery would affect the corneal biomechanics and finally ...

Monitoring thermally-induced lesions with supersonic shear imaging.

Thermally-induced lesions are generally stiffer than surrounding tissues. We propose here to use the supersonic shear imaging technique (SSI) for monitoring high-intensity focused ultrasound (HIFU) therapy. This new elasticity imaging technique is based on remotely creating shear sources using an acoustic radiation force at different locations in the medium. In these experiments, an HIFU probe ...

Medical Physics International

As ultrasonic waves penetrate deep into tissues ultrasound imaging is able to image invisible things by “seeing through tissues” in real time. With the advent of ultrafast ultrasound imaging, the modality can reach thousands of frames per second, much faster than what the human eye can see. A completely new world is revealed as most important physiological processes in the human body occur in t...

Medical ultrasound: imaging of soft tissue strain and elasticity.

After X-radiography, ultrasound is now the most common of all the medical imaging technologies. For millennia, manual palpation has been used to assist in diagnosis, but it is subjective and restricted to larger and more superficial structures. Following an introduction to the subject of elasticity, the elasticity of biological soft tissues is discussed and published data are presented. The bas...
