Casper van Leeuwen successfully defended his thesis ‘Spatial-temporal pathline clustering based on FTLE fields‘ in our group on the 14th of May.
In his work, Casper worked with cardiac flow acquisition data consisting of 3D blood flow of the heart featuring 4D vector fields. These 4D vector fields of the heart are used in clinical research to gain insight in the flow patterns within the heart which in turn can be used to gain a better understanding of the pathogenesis of cardiovascular diseases. He implemented a visualization technique called Spatial-temporal Clustering based on Finite Time Lyapunov Exponents, that aims to circumvent the challenges posed by the structural complexity of the flow and give a concise and insightful representation of the blood flow patterns within the heart. Aside from the main visualization technique this works also introduces a novel probing technique that highlights the base principles of the FTLE fields to provide the user with a better understanding of how a FTLE field works.
We would like to congratulate Casper with his achievement and new title and wish him all the best for the future!
