Applications of digitized frequency modulated thermal wave imaging for bone diagnostics

In recent years, non-stationary, non-invasive imaging methodologies demonstrated as reliable, quantitative, remote characterization and evaluation methods for characterization of biological samples. This present work incorporates a digitized frequency modulated thermal wave imaging (DFMTWI) followed by time domain analysis for bone diagnostics, especially bone with tissue, skin and muscle over layers. With a view to find the potential of the proposed approach a multi layered skin-fat-muscle-bone structure is considered. Results are obtained as correlation coefficient, time delay and phase contrast images. The acquired images clearly shows the ability of the technique to detect the density variations with improved test resolution and sensitivity.
