| Outline of Final Research Achievements |
Ultrasound elastography is an imaging method that measures tissue elasticity based on tissue displacement or elastic wave velocity that is induced by external force. The elastography is classified according to the type of the external force, and we used strain elastography and shear wave elastography. By using the strain elastography, we revealed the validity and reliability of a quantitative method for muscle hardness using two types of tissue mimicking materials, and showed the feasibility of concurrent measurement of muscle hardness and muscle architecture. By using the shear wave elastography, we investigated the relationship between muscle elasticity and thickness of adipose tissue or muscle and the relationship between muscle elasticity and joint flexibility.
