    • The density of a discrete piece of hard tissue such as a bone in a patient may be determined by either of two methods. In a first method, an impulse of energy is introduced into the tissue, and the resulting vibration in the hard tissue is sensed and analyzed to compute the modal damping factor of the tissue, the modal damping factor being directly related to the density of the tissue. In a second method, a continuous energy input is introduced into the hard tissue. The resulting vibration in the tissue is measured with a mechano-electrical vibration transducer (26) and a modal damping factor is calculated. The electro-mechanical vibration transducer (26) of the preferred embodiment measures the pressure with which the transducer (26) is pressed against the patient's flesh and only produces the continuous energy input when a predetermined pressure is achieved which is sufficient to prevent any significant vibration of the flesh surrounding the bone.
    • 诸如患者体内的骨骼的分散的硬组织的密度可以通过两种方法中的任一种来确定。 在第一种方法中,将能量脉冲引入到组织中,并且感测和分析硬组织中产生的振动以计算组织的模态阻尼因子,模态阻尼因子与组织的密度直接相关 。 在第二种方法中,将连续的能量输入引入硬组织。 用机械电振动传感器(26)测量组织中产生的振动,并计算模态阻尼系数。 优选实施例的机电振动换能器(26)测量换能器(26)被压靠在患者肉上的压力,并且仅在达到预定压力时才产生连续能量输入,这足以防止任何明显的振动 的骨头周围的肉体。
