超声成像的原理是使用声波来生成全身肌肉、肌腱、韧带和关节的影像。它可以帮助医生诊断软组织扭伤、拉伤、撕裂和其他软组织疾病。超声波的优势在于安全、无创、不含辐射。超声还可以帮助医生对关节进行动态检查，从而实现更准确和功能性的诊断！

Ultrasound   imaging uses soundwaves to produce pictures of muscles, tendons, ligaments   and joints throughout the body. It is often the gold standard to diagnose   sprains, strains, tears, and other soft tissue conditions. Ultrasound is   safe, noninvasive, and does not use radiation. For orthopedic and sports   injuries your pain often occurs only when you are moving. The ultrasound   allows the doctor to visualize the body while you are moving the joint in   real time, allowing a much more accurate and functional diagnosis.
