Assessment of bone condition by acoustic emission technique: A review

Abstract

The paper deals with the review of acoustic emission technique in biomedical field. The re- view is done with the aim to provide an ov erview of the use of AE technique in biomedical field, mainly co ncentrated on the AE beha vior o f bone under different loading conditions, its depend- ence on strain rate, in osteoporosis, monitoring the fracture healing process of bone. The over- all conclusion from the review was that almost all the studies in bone indicated that the initial AE occurs only in the plastic region and just prior to yield. That means the use of AE tech- nique for clinical application cannot be consid- ered as a safe technique, but the early occur- rence of AE events from callus promises the application of AE technique for monitoring the fracture healing process. The negligible effect of soft tissues on AE response of bone prom- ises AE to become a non-invasive method for assessment of bone condition
