An imaging pipeline for extracting atrial tissue architecture

The 3D architecture of atrial myocardium and its tissue-level variations associated with heart disease are investigated using image-based computer models. Recent studies focus on identification of mechanisms behind longstanding rhythm disorders and optimization of existing treatment strategies. Due to the inherent complexity of atrial geometry, detailed structure-based models require finer aspects of myofiber organisation and anisotropic electrical conduction to be incorporated into them.

In this project, a comprehensive analysis of atrial structure is conducted on 3D images acquired from a dilated sheep atria. This extensive dataset - composed of serial stained block-face images - provides a unique combination of excellent tissue contrast and detailed fiber architecture at high resolution. Novel analytical approaches and visualisation techniques are developed to improve our knowledge about structural coupling in atrial myocardium. Image analysis/processing piplelines are refined/developed throughout using machine learning techniques.
