Karol Karnowski, Air induced deformations for sample properties assessment

PhD, Senior Researcher in Physical Optics and Biophotonics Group, Institute of Physical Chemistry

The need for understanding the mechanical properties of the tissue in its natural conditions paved the way for the development of a new medical imaging modality – elastography. Generally, in elastography, information on biomechanical properties is extracted from the displacement of the tissue due to its mechanical loading. Combination of mechanical excitation and visualization of tissue reaction to the load was pioneered with the imaging technologies like ultrasound and magnetic resonance. Later on, optical modalities such as Brillouin microscopy, Scheimpflug imaging, or atomic force microscopy, enabled mapping the biomechanical properties of the tissue at different organizational levels and scales. It this talk I’ll focus on mechanical excitation with air pulses for ophthalmology applications.
