Item Future research directions with Acoustic Emission and Acousto–Ultrasonic technique(Inderscience, 2015) Shrivastava, SharadThe paper deals with the existing research gap in medical field by the application of non-destructive testing technique. The paper gives an general idea about the various non-destructive testing techniques used in Biomedical field. It also covers the disadvantages of various techniques and how these disadvantages can be taken care by Acoustic emission and Acousto–ultrasonic technique. Based on literature review the gaps have been identified for the future research by these techniques. The assessment of bone condition can be effectively done by using acoustic emission and acousto–ultrasonic technique. Acousto–ultrasonic technique has already proved its usefulness in the assessing the composite materials. As bone is also a composite material, definitely this technique might give good results while assessing the bone condition.Item Assessment of bone condition by acoustic emission technique: A review(Scientific Research Publishing, 2009-03) Shrivastava, SharadThe 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
