Real time stereographic rendering and display of medical images with programmable GPUs

摘要

The study was to explore the power and feasibility of using programmable graphics processing units (GPUs) for real-time rendering and displaying large 3-D medical datasets for stereoscopic display workstation. Lung cancer screening CT images were used for developing GPU-based stereo rendering and displaying. The study was run on a personal computer with a 128 MB NVIDIA Quadro FX 1100 graphics card. The performance of rendering and displaying was measured and compared between GPU-based and CPU (central processing unit)-based programming. The results indicate that GPU-based programming was capable of rendering large 3-D datasets at real-time interactive rates with stereographic displays.
