Conventional 3D ultrasound data reconstruction algorithms have low computational complexity but the huge amount of data generated makes it difficult to compute results within reasonable time on classical computers. In this project we investigate the possibilities of regenerating a 3D isotropic volume from thousands of localized 2D ultrasound images with the help of GPUs.

The Imactis CT-Navigation system consists in a sensor that is inserted into a needle holder which allows to know in real time the position and orientation of the needle. The radiologist moves the needle holder directly on the patient’s skin and visualizes in real time the anticipated trajectory of the needle. So far, the system does only allow to display rectilinear trajectories, 2D slices reconstructed from preoperatory Computed Topography (CT) images. However, the real needle bends under the pressure of various tissues and the radiologist. Needle bending implies that the extracted slices are not flat slices anymore.

Submarine scene demo in OpenGL and CUDA, featuring, animated bubbles as a CUDA particle system with procedural sprites, animated seeweeds as a CUDA mass-spring system, animated water, and finally real time procedural terrain and cave generation (shader based marching cube and procedural marble texture). This project was the opportunity to explore OpenGL and CUDA interoperability.
