Automatic computation of 3D angle of pulmonary artery based on Web3D for preoperative planning in cardiac surgery

Abstract

This paper proposes Web3D technology to improve the general, popular computation method of the 2D angle of the pulmonary artery for preoperative planning of children’s congenital cardiopathy. First, the Web3D technology automatically computes the 3D angle of pulmonary artery to remove the complex process of manual computation of the 3D angle of the pulmonary artery from the 2D angle. Second, due to the adoption of lightweight data transmission technology the computed 3D angle of the pulmonary artery is shown to the front client in the browser in less than 5 seconds in the case of a single 3D angle computation. At last, we test and compare computations of the 3D angle of the pulmonary artery with the mainstream Materialise Mimics. The experimental comparison reveals that our computation precision of the 3D angle of the pulmonary artery is 95 percent through the application of Web3D technology.
