VCA technology enables ultrasound elastography

VISTA, Calif, − March 4, 2015 – BEI Kimco Magnetics has risen to the challenge of meeting the demanding requirements for an ultrasound elastography application using voice coil actuator (VCA) technology.  Elastography is a painless and non-invasive medical imaging technique that measures the elasticity of tissue to provide diagnostic information about the presence or status of disease.  It functions by vibrating the underlying tissue through mechanical excitation to propagate shear waves. These waves can then be measured to assess – for example, liver tissue elasticity – aiding in the diagnosis of various stages of liver fibrosis. This method of mechanical vibration has proven particularly more effective in evaluating tissue stiffness of obese patients over other ultrasound elastography technologies.
