摘要

The potential critical influence of impingement angle and scanndirection on B-scan imaging for tissue classification is explored innthis work. The effects of variations of other system parameters onnB-scan images are also investigated. Particular attention is paid to theninfluence of the direction of propagation of the interrogating wavenwithin the tissue structure. This is done in order to explore thenhypothesis that the detection of malignant areas embedded inside a hostnordered tissue can be improved by exploiting the disordered structure ofnthe diseased region. Results of preliminary experiments performed on anphantom give an indication that speckle pattern variations due tonimpingement angle and/or scan direction can occur that relates to thenstructural properties of the tissue from a scattering point of view.nSample problems are presented to differentiate the structural variationsnwithin a tissue by analyzing a phantom constructed of unidirectionalnfibers arranged in layers that are staggered with respect to each other
