Development of an Optical Elastomicroscopy for Imaging Tissue Elasticity in High Resolution
Articular cartilage is a thin but crucial tissue layerwhich plays an important role in diarthrodial joints. During thelast decade, the quantitative ultrasound technique, especially thehigh frequency ultrasound elasticity measurement technique,called as ultrasound elastomicroscopy (UEM), has been widelyemployed as a versatile modality to investigate the articularcartilage. Ultrasound elastomicroscopy can measure thedeformation of different layers of articular cartilage undercompression, but whether the propagation of ultrasound intissues was changed or not with the imposed load is still unknown.In this study, we developed a new optical method to validate theaccuracy and reliability of the ultrasound elastomicroscopy.Layered sponge phantoms were prepared for the experiments.During the compression, both the ultrasound and opticalelastomicroscopy systems were employed to record theultrasound signals and optical images from inside and the font of the phantoms. The deformations of the phantoms from differentlayers were tracked from both ultrasound and optical signals andwere then compared. The preliminary results suggest that themeasurements of the ultrasound elastomicroscopy system couldbe validated.
