Skin Cancer Diagnosis Using Torsional Wave Elastography: A New Approach
54º Congreso Español de Acústica — Tecniacústica 2023
Abstract
A new technique based on propagation of shear elastic waves into the skin tissue, called Torsional Wave Elastography (TWE) for diagnosis of skin cancer and characterization of skin mechanical properties is presented. Non-invasive diagnostic methods are desirable to avoid invasive procedures and potential complications. The technique evaluates three biomarkers: elasticity, viscosity, and anisotropy. A TWE device able to generate shear elastic waves at 0.4-1 kHz was developed providing information about the mechanical properties of the tissue. TWE tests were conducted on patients and the results were evaluated by considering Histopathology as the gold standard.
