2009 Summer Project Week Cone Beam backprojection

Key Investigators

• U Michigan: Zhou Shen, Jeff Fessler, James Balter
• MGH: Greg Sharp

Objective

We will be taking an inventory of 2d/3d registration algorithms available between our groups, and accelerating at least one using CUDA for NVIDIA hardware.

Approach, Plan

A commmonly used algorithm for Cone Beam CT reconstruction is the Feldkamp backprojection method. We plan to implement this in CUDA to evaluate the speed, and wrap it into an interface that will accept as input Varian Cone Beam CT projection images,

Progress

To be filled in later.
