Developing Artificial intelligence-based approach for automated reporting of CT Coronary Angiogram and computation of Fractional flow reserve from Coronary CT Angiography and Invasive Coronary Angiography in patient with coronary artery disease. Currently Fractional Flow Reserve is done by invasively inserting a pressure wire in artery to determine the FFR values. It is very invasive, costly and time-consuming processing. Our Chief Medical Officer is interventional cardiologist from past three decades and based on his and his collegue experience he defined the need to us.
