Article Synopsis
  • The study introduces a new preclinical device that uses Torsional Wave Elastography (TWE) to measure the stiffness of elastic materials and soft tissues.
  • The device consists of a rotational actuator and a piezoceramic receiver, allowing shear waves to interact with tissue before being collected for analysis.
  • Experimental tests showed that the device provides reliable, accurate stiffness measurements, with over 95% correlation to established techniques, suggesting potential for medical applications, especially in studying cervical properties during pregnancy.

Estimating the tissue parameters of skin tumors is crucial for diagnosis and effective therapy in dermatology and related fields. However, identifying the most sensitive biomarkers require an optimal rheological model for simulating skin behavior this remains an ongoing research endeavor. Additionally, the multi-layered structure of the skin introduces further complexity to this task.

This paper presents a novel method for reconstructing skin parameters using Probabilistic Inverse Problem (PIP) techniques and Torsional Wave Elastography (TWE) rheological modeling. A comprehensive examination was conducted to compare and analyze the theoretical, time-of-flight (TOF), and full-signal waveform (FSW) approaches. The objective was the identification of the most effective method for the estimation of mechanical parameters.
