Megjegyzések:Parallelization methods and modern OpenGL based visualization in multimodal medical imaging were two different techniques until the appearance of the new generation Graphics Processing Unit (GPU). The increased calculation and memory capacity of this new hardware allows using it as parallelization and visualization tool, as well. Given this facility, we also investigated the applicability of the latest G80 chip based VGA card in iterative image reconstruction and image algebra. Considering the above, we implemented real-time multimodal visualization tasks using the shading languages and iterative image reconstruction running on the GPU with CUDA. Several test applications have been developed using our MultiModal Medical Imaging (M3I) software environment for this study. In these applications GPU shaders were implemented and applied to 2D and 3D multimodal image processing and visualization methods related to digital brain atlas technique and tensor imaging. We found that the full 3D texture based rendering methods, coming with the recent GPU hardware, have further opportunities to improve and combine the implemented image processing and visualization components. However, effective application of these features on the large output data acquired from the most advanced imaging devices such as PET/CT scanners requires further examination. The implemented parallel 2D iterative reconstruction programs running on GPU and a multiprocessor system resulted the same reconstruction time, which falls off from the expected speed growth for the good of GPU.
