Abstract:
n 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.
