GPU accelerated algebraic iterative reconstruction for cone beam x-ray micro CT

Will Thompson (University of Manchester)

Frank Adams Room 1, School of Mathematics, Alan Turing Building,

Cone beam x-ray micro CT is a technique for imaging objects from their x-ray projections, using a single x-ray source and a flat panel detector. Well-known analytical methods exist for reconstruction, but these perform poorly under less than ideal data acquisition conditions, such as limited numbers of projections or reduced exposure time. Algebraic iterative reconstruction methods offer the potential for much better image quality under such conditions, but are generally considered unfeasible for reconstruction of real data sets due to their high computational demands. The talk will discuss a new algorithm for calculating the key discrete forward and back projection steps, and its efficient implementation on GPU.
