About the Project
This proposal is designed to use transient wave method and phase sensitive OCT (PhS-OCT) system to provide localized and quantitative mechanical property of layered biological tissues, especially skin. The velocities of transient waves, i.e. shear wave (SW) and surface acoustic wave (SAW) are closely correlated to material stiffness, i.e. transient waves are propagating faster in hard material and slower in soft material. SAW and SW can be generated by a Q-switched laser pulse. SW is propagating in epidermis and upper dermis of skin (1-~1.5 mm), while broad-band SAWs have the nature of dispersion (different frequency contents penetrate into different depth with different velocities), by analysis the different velocities of different frequency contents of SAW signals we can obtain the quantitative elasticity information of dermis and subcutaneous fat layer of skin (~1 mm-~4 mm). A PhS-OCT is used to measure the both SW and SAW signals propagating on the sample surface, in addition to provide high resolution structure image of skin. This method is feasible to provide the bulk quantitative Young’s modulus value of all epidermis, dermis and subcutaneous subcutaneous fat layer, and skin structure analysis, i.e. surface condition and skin layer thickness measurement at the same time. It would be possible to use in clinical diagnosis and treatment of different kinds of skin diseases with various requirements.
This proposal aims to develop a novel non-contact transient OCE system capable of quantitatively measuring the biomechanical properties of tissue to aid a rapid and accurate diagnosis and assessment of tissue abnormalities. This study involves collaborative and multidisciplinary research to create a new imaging technology capable of accurate quantitative measurement of human skin layers with ultrahigh resolution in real time.
