Abstract
As CT scanning is a very common medical imaging method, we propose new
hardware-based algorithms using GPU (Graphical Processor Unit) programming
for rapid visualization. Firstly, 3D volumes are constructed from CT scans.
Then volume rendering is used to display anatomical structures via
algorithms founded on improved ray casting and 2D textures. Our methods
achieve interactive rendering rates and require an ordinary PC with an
off-the-shelf graphics card. We expect our approach to be useful to medical
practitioners for handling modern, large-scale medical datasets.
