Research Abstract

A newly developed high-frequency ultrasound imaging system (HFUIS) provides noncontact high-resolution 3D ultrasound (US) imaging. A Transducer with central frequency of 120 MHz and a focal length of 3.2 mm was most appropriate for evaluating the articular cartilage. We divided the articular cartilage in three layers (superficial, middle and deep layers) and compare the images with those of scanning acoustic microscope (SAM). A high relative intensity by HFUIS and high sound speed area by SAM had strong correlations (Pearson product moment correlation, superficial layer: 0.704, middle layer: 0.731).
