ULTRASONIC SYSTEM AND METHOD FOR MEASUREMENT OF OCULAR BIOMECHANICS

摘要

A system and a method for non-invasively ultrasonically measuring biomechanical properties of ocular tissue in vivo is presented. The method comprises positioning an ultrasonic transducer proximally to the ocular tissue. Reflections of the ocular tissue can be ultrasonically obtained using the ultrasonic transducer. The ultrasonic reflections can be converted into reflection spectra. Biomechanical properties of the ocular tissue, such as, for example, thickness, corneal stiffness, density, and longitudinal modulus, can be determined based on the reflection spectra. A wave propagation model can be developed to simulate ultrasound propagation of ocular tissue in vivo. The ultrasonic non-destructive evaluation method and system for the non-invasive measuring of reflection spectra and determining biomechanical properties of ocular tissue in vivo can provide information for ocular disease management and therapeutic and refractive procedures.
