Ultrasound and elasticity imaging of joints and other soft tissues

Summary

Elisa E Konofagou, Ph.D.

Technology Benefits

Non-invasive for analysis of tissue properties without physical contact Provides information on mechanical properties over time for analysis of complex, viscoelastic tissuesCan be used for time-dependent imaging of displacement and strain distributionsCapable of measuring fundamental mechanical properties including Young's modulus, shear modulus, and Poisson's ratioPatent information:Patent Pending (WO/2007/067987 &maxRec=44) )Patent Pending (US/2009/0221916)Tech Ventures Reference: IR 1877

Technology Application

Monitoring replacement graft mechanical properties following reconstruction of the ACL or other ligaments and soft tissuesFull characterization of mechanical properties of joints and soft tissuesDiagnosis and monitoring of abnormalities in joint or tissue stiffnessTool for helping to develop and monitor physical therapy programs for joint rehabilitationUse in guiding graft placement in ACL repair or the repair of other ligaments and tendonsProbe for use in arthroscopic surgeryDiagnosis of joint diseases including osteoarthritis or osteoporosis
