A cortical-bone structural geometry phantom: dental plaster as a convenient and radiologically similar fabrication material

Abstract: Areal bone mineral density (aBMD), derived from dual-energy X-ray absorptiometry (DXA) scanners is used routinely to infer bone strength. With DXA hip scans there is growing acceptance of the advantages of also measuring bone structural geometric variables, that complement conventional aBMD to improve understanding of bone modelling, remodelling and processes of metabolic bone disease. However, phantoms for assessing structural geometric variables from DXA scans are not widely available, unlike those for aBMD.… Show more

“…We have not yet published the method but we showed an in vivo comparison between a 64 slice GE MDCT scanner and JHU HSA using Hologic DXA scans at the 2007 ASBMR meeting(3). In collaboration with Dr. Benjamin Khoo of the University of Western Australia we have also developed a femur geometry phantom to provide an absolute reference standard for both DXA and QCT(4). …”
