An Interactive Virtual Reality System for Cardiac Modeling
To help medical colleges train students better, help physicians achieve a better preoperative preparation, and help patients understand their condition better, an interactive virtual reality (VR) system is proposed in this paper for cardiac modeling. First of all, we processed the cardiac images acquired by the gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) to generate the MPI color model in Matlab. Secondly, the MPI color model is fused with the computed tomography (CT) surface model in Matlab. Thirdly, the fused model is imported into Unity3D. Finally, we constructed an interactive VR system with the operating room environment and operated on the fused model virtually. The experimental results show that this system can achieve satisfying performance as expected.
