Calibration of the fat and muscle hyperelastic material parameters for the assessment of the internal tissue deformation in relation to pressure ulcer prevention

Abstract

Presented work shows the possibility of using the US data for the assessment of the soft tissues’ material properties. This is clinically relevant, since US allows to obtain a subject-specific anatomical data, while being much more accessible and less costly than MRI. Results also imply the importance of using several parameters representing different types of soft tissues for the inverse optimization of the material properties.
