In order to let the doctor carry on the coronary artery diagnosis and preoperative planning in a more intuitive and more natural way, and to improve the training effect for interns, an augmented reality system for coronary artery diagnosis planning and training (ARS-CADPT) is designed and realized in this paper. At first, a 3D reconstruction algorithm based on computed tomographic (CT) images is proposed to model the coronary artery vessels (CAV). Secondly, the algorithms of static gesture recognition and dynamic gesture spotting and recognition are presented to realize the real-time and friendly human-computer interaction (HCI), which is the characteristic of ARS-CADPT. Thirdly, a Sort-First parallel rendering and splicing display subsystem is developed, which greatly expands the capacity of student users. The experimental results show that, with the use of ARS-CADPT, the reconstruction accuracy of CAV model is high, the HCI is natural and fluent, and the visual effect is good. In a word, the system fully meets the application requirement.
