2009 Summer Project Week Cone Beam backprojection

Key Investigators

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

Objective

We will be providing infrastructure for investigation of modifications to cone beam Ct reconstruction methods to support future research in image-guided radiation therapy (IGRT)

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.
