提出了一种简单的技术，可以确定阻尼的程度和阻尼的导管换能器系统的谐振频率。根据这些数据，可以确定液压正弦频率响应以及无阻尼（自然）频率。该技术包括在无气泡、充满液体的导管传感器系统中突然释放压力，同时用条形图记录仪记录压力。
A simple technique is presented that allows determination of the degree of damping and the damped resonant frequency of catheter-transducer systems. From these data, the hydraulic sinusoidal frequency response, as well as the undamped (natural) frequency can be determined. The technique consists of suddenly releasing pressure in a bubble-free, fluid-filled catheter-transducer system while recording pressure with a stripchart recorder.
