MATLAB implementation of the one-dimensional unwrapping algorithm and post-processor

Visualization 4

Visualization of the overlay between the histological image and registered stiffness map of a WHO grade I meningioma brain tumor. The histology image is also displayed in grayscale for better visualization and differentiation from the stiffness map

Visualization 2

Simulation of the proposed unwrapping algorithm. The figure shows the displacement curve of a WHO grade IV glioblastoma brain tumor sample caused by a 370 µN strong force of the air-jet for a specific axial depth in blue. The corresponding force distribution of the air-jet is shown in light gray

Visualization 3

Phase-sensitive OCE measurement of a WHO grade IV glioblastoma brain tumor. The force curve of the air-jet, the displacement curve for a given axial depth, and the displacement maps with their corresponding B-scans are shown. The position of the exemplary displacement curve is marked by a white star in the B-scans

Visualization 1

Demonstration of the effect of high forces on biological tissues through the example of a glioblastoma brain tumor tissue. In total, 1000 B-scans with 2048 A-scans were recorded, corresponding to a measurement time of 1.63 s. A mechanical stress of 10 mN and a 600 ms long air pulse were applied to the sample using the air-jet system described in chapter 2

Supplementary document for Phase unwrapping for MHz optical coherence elastography and application to brain tumor tissue - 6792313.pdf

Investigation of the impact of applying a constant force between 31 and 33 µN on diverse PVA phantoms with various elastic moduli ranging from 875 Pa to 16.38 kPa. The applied force values are specified for each measurement
