Learn about HeartFlow's unique approach for better diagnosis and treatment of cardiovascular disease. From CT images, HeartFlow creates a complete geometric and physiologic model of the patient's coronary anatomy. Blood flow is simulated using computational fluid dynamics to functionally assess narrowings of the coronary artery. HeartFlow's approach is approved by regulatory bodies and in commercial use around the world today. We'll focus on DeepLumen, the fast and highly accurate method for extracting coronary arteries from a CT scan. It is formulated as a novel 3D rotational CNN that exploits translational and cyclic symmetries. DeepLumen is shown to be at least as accurate as expert radiologists in quantifying disease compared to invasive catheterization measurements.
