Abstract	Currently, echo imaging is widely used as a medical imaging method due to its portability, low cost and spatiotemporal resolution. Another tomography method using ultrasound, USCT (Ultrasound Computed Tomography) acquires reflected wave as well as transmitted wave, which can reconstruct the profile of medium sound speed. Greenleaf et al.1 showed that sound speed and attenuation index could be used to distinguish benign masses from cancer by measuring the sound property in a breast. However, this method was not used as populer clinical imaging method due to the limited performance of CPU in those days. Duric et al.2 developed the Computed Ultrasound Risk Evaluation (CURE) for the whole breast imaging system with high performance computing system. In this system, sound speed and attenuation profile in the breast is main target for diagnosis of breast cancer. On the other hand, the ring array transducer and ring synthetic aperture echo imaging3 as shown in Fig.1 was suitable for a shadow-less scatter imaging. From this point of view, the combination method of the ring array transducer and ring synthetic aperture imaging has a possibility for imaging of orthopedic applications. In this paper, preliminary trails to orthopedic applications using ring array was described.
