Transillumination techniques in ophthalmic imaging
… is typically performed in a reflection geometry. Images are formed from light that has backscattered off corneal microstructures or backreflected from the retina. In this configuration, artifacts caused by superficial surface reflections are often encountered. These unwanted reflections can either …

PET-imaging in depression and antidepressant therapies : focus on the serotonin system and the cerebral glucose metabolism
… distribution and to define the appropriate image quantification methods. Subsequently, this radiotracer was used to perform a dose-occupancy in the dog to estimate the optimal dosing regimen to treat dogs with behavioural disorders with escitalopram. A second part of the dissertation focuses …

Improved quantification in small animal PET/MR
… the use of sequentially acquired PET and MR images to improve the quantification of small animal PET data. The primary focus was to improve image-based estimates of the arterial input function (AIF), which defines the amount of PET tracer within blood plasma over time. The AIF is required to …

A Translational Approach to Modeling Unique Aspects of Germ Cell Development During Self-Organization of the Primate Embryo
… embryo. We harness this power, using single cell image quantification and genetic tools including CRISPR-Cas9 to probe further into the signaling environment of the hPGC niche in the gastruloid model. We elucidate the role of each leg of the BMP4 – WNT – ACTIVIN/NODAL signaling cascade in …

Development of Quantitative Tools for the Characterization and Analysis of the Blood Brain Barrier in Normal and MPS IIIB Mice
… technologies in confocal microscopy and 3D image analysis to develop and utilize methodologies to analyze each of the components of the BBB in wild type mice with the goal to quantify their relationship with the cerebral microvascular endothelial cells. In doing so valuable image processing …

Improved Visualization and Quantification for Hyperpolarized 129Xe MRI
… both visualizing and qualifying the resulting images. Before that, a standardized acquisition with a well-understood relationship between 129Xe dose and image quality needs to be established for efficient and cost-effective acquisitions. Moreover, we also seek to understand the origins of …

The Mechanism of Action of Hyaluronan Therapy as a Treatment for Osteoarthritis and the Assessment of Osteoarthritic Articular Cartilage Using Ultrasound
… across multiple modalities. B-mode ultrasound images were analysed using Grey Level Co-occurrence Matrix (GLCM) textural features to quantify cartilage surface integrity and internal microstructural organisation. This approach was validated in 30 human participants, enabling identification of …
