本文介绍了一种用换能器振动法测量骨声阻抗的方法，该方法可以缩短测量时间而不使病人受到束缚。在基于干涉的反射型测量方法中，身体运动是一个问题;因此，期望在短时间内完成测量。此外，为了消除运动的影响，通常将待测量的身体部位牢固地捆绑起来。然而，考虑到受试者的负担，这是不可取的。这种方法允许在不牢固地束缚患者的情况下，在传统方法所需时间的1/6内测量声阻抗。
In this paper, we describe about a transducer vibration method for the measurement of acoustic impedance of bone, which enables to shorten the time of measurement without binding the patient. In the interference-based reflection-type measurement method, body motion is a problem; therefore, it is desirable to complete measurement in a short time. In addition, to eliminate the effect of motion, the part of the body to be measured is usually bound firmly. However, considering the burden on the subject, this is not desirable. This method allows acoustic impedance to be measured in 1/6 the time required by the conventional method without binding the patient firmly.
