| 摘要 |
The present invention provides an apparatus for non-invasive determination of bone mass, said apparatus having a platform for supporting a bone to be measured, a spring having a selected stiffness which connects the platform to a sensor capable of measuring vibration velocity and force, and a vibrating means connected to the sensor, wherein the vibrating means exposes the sensor, the spring and the platform to vibration so that vibration velocity and force can be measured by the sensor and the mass of the bone determined. A second apparatus for non-invasive determination of bone mass having a gripping means, a spring having a selected stiffness which connects the gripping means to a platform for positioning of a bone, a sensor capable of measuring vibration velocity and force which connects the platform to a vibrating means, and a vibrating means which vibrates the sensor, the platform, the spring, and the gripping means so the vibration velocity and force can be measured by the sensor is also provided. In addition, a method of non-invasively determining mass of a bone with these apparatuses is provided.
