Ultrasonic Evaluation of Local Biological Tissue Anisotropy

Popis výsledku v původním jazyce

Anisotropy level of human skin is typically obtained by multi-axial tensile test, cutometry, elastography, ultrasonic imaging, etc. Most of the methods are time-consuming, expensive, or not suitable for in-vivo measurements. In this paper a new easily-applicable method for immediate evaluation of human skin local anisotropy is described. Results in this area are of great interest in dermatology, plastic surgery, and cosmetics. The method is also utilizable in many industrial applications for anisotropyevaluation of various materials like composites, etc. Proposed system exploits a special flexible multi-directional circular probe with built-in piezoelectric elements (ultrasonic array) for elastic waves propagation measurement. The anisotropy level ofthe tested structure is determined from directional dependence of elastic wave velocity related with complex elastic modules of the specimen. The method was tested on human skin tissue in-vivo and a composite sample. Comparative tests on
