Background, Motivation and Objective It is important to evaluate the elasticity of tissue-engineered cartilage, for evaluating its structural strength. However, in vivo evaluation of tissue-engineered cartilage elasticity has not been established. Although the elastography is the one of promising technique for evaluating tissue elasticity, it might be difficult to apply to the tissueengineered cartilage because its size is small and internal echo from normal cartilage is weak. On the other hand, the speed of sound (SOS) is available for elasticity evaluation. We have proposed in vivo measurement method of SOS using ultrasound and MR images. This method determines the SOS based on the thickness measurement using the MR image and the time-of-flight (TOF) measurement using the ultrasound. In this study, this method was applied to the SOS measurement of tissue-engineered cartilage.
