Quantitative Multi-Modal Optical Coherence Photoacoustic Elastography
Ekaterina Sherina, Lisa Krainz, Wolfgang Drexler +1
We present a novel multi-modal optical coherence photoacoustic elastography framework, which combines two imaging modalities, optical coherence tomography and photoacoustic tomogra…
On a PDE-based material parameter identification problem with contact constraints
Simon Hubmer, Stefan Kindermann, Ekaterina Sherina
We consider the identification of a scalar coefficient in a PDE-based parameter estimation problem with contact constraints. The considered problem can be used as an idealized mode…
On the Intensity-based Inversion Method for Quantitative Quasi-Static Elastography
Ekaterina Sherina, Simon Hubmer
In this paper, we consider the intensity-based inversion method (IIM) for quantitative material parameter estimation in quasi-static elastography. In particular, we consider the pr…
On Phase Unwrapping via Digital Wavefront Sensors
Simon Hubmer, Victoria Laidlaw, Ronny Ramlau +2
In this paper, we derive a new class of methods for the classic 2D phase unwrapping problem of recovering a phase function from its wrapped form. For this, we consider the wrapped…
