电流测量探头采用自积分的罗柯夫斯基线圈，自积分电阻的电感、电容要尽可能的小，并采用同轴结构。

The Rogowski coil ranged in the same axis was used as current sensor, in which the self-integral resistance should has smaller inductance and smaller capacitance as possible.

另外，超声检查过程中，自探头输出射频回声数据积分和非在线弹性影像重建。

In addition, the radiofrequency echo data stored during us were exported from the scanner and used for off-line strain image reconstruction.
