Effectiveness of Biomaterial Coating on Bone Density Diagnosis Using Modulated Thermal Wave Imaging: A Numerical Study

Active thermography is one of the promising painless techniques for bone density detection. It can defeat constraints of conventional diagnostic techniques such as X-ray. However, it has limited depth penetration in the body which has limited resolution. Despite the fact that, to further develop depth penetration, a modulated thermal excitation utilized alongside various postprocessing methods is utilized, it is still restricted. Thus, in this work, we propose a nanoparticle coating method alongside linear frequency modulated excitation (LFM). This work centers around testing the impact of nanoparticle coating along with LFM on the bone FEM model which has various bone densities. Further, we compare various coating results with post-processing methods using signal to noise ratio (SNR). After comparing all we conclude that for bone density detection both the silver and iron-based nanoparticle coating are capable to enhance the depth penetration however the silver nanoparticle along with pulse compression based post-processing gives a higher SNR value.
