体育科研教学中肌肉影像测量技术比较

Comparison of Muscle Image Measurement Techniques in Sports

采用比较分析法等,对肌肉形态非侵入性量化方法比较,认为肌肉形态测量方法互补,为体育科研、教学提供多种需求。CT康价,应用广,但具有使人体被辐射风险;超声波仪亦便宜,应用便捷,但精度较差、耗时较长;MRI可避免辐射,对软组织分辨和空间定位具有较高的敏感度,可连续的进行三维扫描身体任何部位、器官,目前仍被认为是肌肉影像学中一个"金标准",但价格昂贵。近几年出现的三堆超声、全景超声、实时超声等新技术,使得超声技术有望进一步发展。

Comparative analysis method for non--invasive method to quantify muscle morphology comparison, it shows that muscle morphometry methods complement each other and providing a variety of needs for sports research and teaching. CT is cheap and wide application, it has the body exposed to particle radiation risks; Ultrasonic instrument is also cheap and with good results for muscle dynamic image, but has poor accuracy and time. consuming I Although the high cost and time-consuming of MRI technology, but it is still considered to be a ＂gold standard＂. New technology is expected to make further development, such as real--time ultrasound.
