ABSTRACT:
The invention discloses a bone examination apparatus which includes a shaking module, a multi-mode ultrasonic detecting module, and a processing module. The shaking module is disposed close to a distal end of an examinee's femur, for inputting a shaking signal to the distal end. The multi-mode ultrasonic detecting module is disposed close to a near end of the examinee's femur, for detecting the shaking signal through the examinee's femur at the near end and generating a detecting signal. Additionally, the processing module is connected to the shaking module and the multi-mode ultrasonic detecting module respectively, for determining the examinee's bone density in accordance with the shaking signal, the detecting signal, and a first criterion.
