Measurement of BMD in Dual-Energy X-ray Absorptiometry - A Review

Application of DEXA scan in healthcare applications have recently become one of the most active research platforms. Since the DEXA exhibit novel and superior properties compared to conventional scan and create a new challenging boom in medical era. Having a deeper look into the specific features of DEXA, this paper provides a literature survey on DEXA. DEXA is the most common method used for the Bone mineral density (BMD) estimation to assess fracture risk. Only a very few papers explain the importance of DEXA and this paper explains the need of DEXA and its role in BMD. The objective of this paper is to present a survey on DEXA that appeared in the literature over the past decade under all severe conditions that were not discussed in the previous survey. The paper focuses on the Principles, fundamentals and modalities, techniques and salient contributions of DEXA.
