A GPU approach for accelerating 3D deformable registration (DARTEL) on brain biomedical images
Pedro Valero‐Lara · 2013
Medical image processing is becoming a significant discipline in bioinformatic. Particularly, deformable registration methods are one of the field most important in the biomedical image processing, due to the valuable information provided. However, these methods consume a considerable processing time and memory requirements. Current GPUs have a high number of cores and high memory bandwidth providing an excellent platform for reducing the cost of these methods in terms of processing time. In this work, it is proposed a Graphics Processing Units (GPU)-based implementation of one of the most sophisticated deformable registration algorithms, DARTEL. The experimental results show a processing time reduction higher than 2 hours in typical cases of study. Moreover, the power consumption is also reduced in a significant amount.
