Abstract

Coronary artery diseases such as atherosclerosis are the leading cause of death in the industrialized world. In this project, we develop computational tools for segmentation and registration problems on intravascular images including IVUS (Intravascular Ultrasound) and OCT (Optical Coherence Tomography). One sample component of this project is Automatic Stent Implant Follow-up from Intravascular OCT Pullbacks. The stents are automatically detected and their distribution is analyzed for monitoring of the stents: their malpositioning and/or tissue growth over stent struts.

Clinical Relevance

Coronary Artery Disease (CAD) still remains the leading cause of morbidity and mortality among western countries. The appearance of CAD can range from stable angina pectoris to acute coronary syndromes (ACS), which are associated with increased mortality. Acute coronary syndromes are usually caused by acute plaque rupture, which leads to local thrombosis and occlusion of the respective coronary vessel. The localization of atherosclerotic lesions is not randomly distributed but show a characteristic pattern with preferred location at branches or bends. This results in locally different shear stress levels and flow-tissue interaction which can promote atherosclerosis.
