       abstract = "A common task in medical image analysis is the alignment of data from different
         sources, e.g., X-ray images and computed tomography (CT) data. Such a task is generally known as
         registration. We demonstrate the applicability of automatic differentiation (AD) techniques to a
         class of 2D/3D registration problems which are highly computationally intensive and can therefore
         greatly benefit from a parallel implementation on recent graphics processing units (GPUs). However,
         being designed for graphics applications, GPUs have some restrictions which conflict with
         requirements for reverse mode AD, in particular for taping and TBR analysis. We discuss design and
         implementation issues in the presence of such restrictions on the target platform and present a
         method which can register a CT volume data set (512 × 512 × 288 voxels) with three X-ray
         images (512 × 512 pixels each) in 20 seconds on a GeForce 8800GTX graphics card.",
