Study of the Contrast Mechanism in an Acoustic Image for Thickly Sectioned Melanoma Skin Tissues with Acoustic Microscopy
Summary
This chapter presents the results of a study to use broadband frequency acoustic microscopy to carry out digital imaging and computer simulation to characterize tissue. Since contrast in an acoustic image for skin tissue including a cancerous portion is formed by attenuation differences within the tissue, prediction of the amplitude of a transducer output is important for the field of medical ultrasound. An abnormal skin tissue was selected as a specimen, and compared to a normal skin tissue. The technique suggests the use of this approach as a diagnostic tool and opens the door for more sophisticated analysis. The author develops a mathematical modeling for a five-layer acoustic wave propagation system. The results indicate both qualitative and quantitative differences between normal and abnormal melanoma tissue, thus paving the way for a potentially useful diagnostic medical tool without the need for staining tissue as is most often required in optical imaging.
