Computational medicine is an emerging field that uses quantitative approaches to solving problems in human health and disease including diagnosis, treatment, and understanding causative mechanisms. In recent years, the advent of big data has sprouted approaches to understanding mechanisms of disease by combining traditional algorithms with data-driven approaches.
At HeartFlow, we have built one of the largest databases of human coronary artery trees with associated clinical information. I have developed AI based algorithms to predict both anatomic and hemodynamic information in real time with high accuracy compared to annotated “ground truth” data.
