RTK: Reconstruction Toolkit

Objective

To develop an open-source software for fast cone-beam CT reconstruction compatible with ITK. Subsequently, the library could be extended to other modalities and geometries, and used for 2D/3D registration.

Requirements

• 2D pre-processing (raw-data to attenuation images, i.e. logarithm, ghosting and scatter correction, etc…);
• 2D Fourier filtering (or 1D per line/column);
• 3D => 2D forward projection;
• 2D => 3D backprojection;
• Respiratory signal extraction;
• 3D => 3D => 2D deformable forward projection;
• 2D => 3D => 3D deformable backprojection.

Other solutions

• Plastimatch
• STIR
• VTKEdge
• ITK
• Aspire
• OSCaR
