TL;DR: In this article, a gray-scale-based deformable image registration (DIR) algorithm called demons and five of its variants were implemented on GPUs using the compute unified device architecture (CUDA) programming environment.

TL;DR: It is interesting to find out that the original passive force demons algorithms outperform subsequently proposed variants based on the combination of accuracy, efficiency and ease of implementation.

TL;DR: This paper has implemented the dose planning method (DPM) Monte Carlo dose calculation package on the GPU architecture under the CUDA platform and demonstrated adequate accuracy of the GPU implementation for both electron and photon beams in the radiotherapy energy range.

TL;DR: This work presents the implementation of an intensity-modulated radiation therapy (IMRT) optimization algorithm on graphics processing units (GPUs) using a penalty-based quadratic optimization model, which is solved by using a gradient projection method with Armijo's line search rule.

TL;DR: This work may help explain epidemiologic data regarding the pelvic floor impact of a first delivery and the models and simulation technique need refinement, but they may help study the effect of labor parameters on the pelvicfloor.
