生物力学 Biomechanics


 

生物力学研究人员正在研究大鼠胫骨前肌的收缩。 他们期望快速准确地量化整体运动以及局部变化。

Biomechanic researchers were studying the contractions of a rat Tibialis Anterior muscle.  It was desirable to quickly and accurately quantify the overall movements, as well as localized variations

 

技术挑战 Challenges

由于实验涉及活体组织,因此常规测量手段很难应用,并可能干扰研究中的运动。 测量的关键点是如何尽可能快的获取尽可能多的数据。 标记跟踪方法已被使用,但只能提供总平均值。 而研究人员处理这类信息也费时费力。

Because the experiments involved live tissues, conventional gauges were difficult to apply and tended to interfere with the motion under study.  It was important to capture data quickly, and for as many points as possible.  Marker tracking had been used, but provided only gross averages.  It was also time-consuming and tedious for the researchers to process this type of  information.

CSI公司的VIC-3D系统可快速捕捉整个肌肉表面的收缩数据。 由于系统的速度和易用性,可以在精确的时间间隔内进行多次测量。 该方法与被测标本没有相互作用,全场数据也使得实验人员无须提前猜测哪些区域的测量更有意义。

Correlated Solutions’ VIC-3D system was used to rapidly capture contraction data over the entire muscle surface.  Due to the system’s speed and simplicity, it was possible to make numerous measurements at precisely timed intervals.  There was no interaction with the specimen, and no need to guess which areas would be of greatest interest.

测量结果提供了很高空间分辨率,并且请易可以识别肌肉组织的“聚集”引起肌肉收缩的显着变化的许多区域。 这些地区以前无法用传统的方法确定。 最后,所有结果的计算都自动完成。 这节省了大量时间并避免了数据处理中出现人为错误的可能性。

The resulting measurements provided high spatial resolution and made it possible to identify numerous areas where “bunching” of the muscle tissue caused significant variations in muscle contraction.  These areas had not been previously identified with conventional methods.  Finally, all calculations were done automatically.  This saved considerable time and avoided the possibility of human error in the data processing.
