17. Exploring Deep Learning Frameworks for Multiclass Segmentation of 4D Cardiac Computed Tomography
University essay from Linköpings universitet/Institutionen för hälsa, medicin och vårdAbstract : By combining computed tomography data with computational fluid dynamics, the cardiac hemodynamics of a patient can be assessed for diagnosis and treatment of cardiac disease. The advantage of computed tomography over other medical imaging modalities is its capability of producing detailed high resolution images containing geometric measurements relevant to the simulation of cardiac blood flow.
