This study takes a look at different DRR generation methods for use in intensity based 2D/3D Image Registration. A specific emphasis is placed on whether the methods are trivially paral-lelisable with the aim to take advantage of hardware systems with more than one CPU. The ray casting algorithm and light field rendering are found to be suitable for this(More)
At iThemba Labs, we are constructing a patient positioning system for proton therapy. This system will use stereo vision techniques to accurately position the patient relative to the beam line. To do this, we need to be sure that the vision system is functioning correctly. In addition to various procedural checks, we implement a variety of software tests to(More)
In previous work, we demonstrated that a linearity condition was sufficient for us to estimate distortion from the output of the Synthetic Discriminant Function (SDF). However , many variants of the SDF have been developed. We extend the linear interpolating property to a class of SDF variants and use this result to analyse the properties of two of these(More)
