已经开发了大量的算法来执行非刚性配准，并且它是医学图像分析中常用的工具。自由变形算法是一种成熟的技术，但非常耗时。在本文中，我们提出了一个并行友好的制定适合图形处理单元执行的算法。使用我们的方法，我们在不到1分钟的时间内完成了T1加权MR图像的配准，并且在执行分割传播时显示出与经典串行实现相同的准确度。这项技术在时间紧迫的应用中可能具有重要的实用价值，例如图像引导干预或处理大型数据集。(C)2009爱思唯尔爱尔兰有限公司保留所有权利。
A large number of algorithms have been developed to perform non-rigid registration and it is a tool commonly used in medical image analysis. The free-form deformation algorithm is a well-established technique, but is extremely time consuming. In this paper we present a parallel-friendly formulation of the algorithm suitable for graphics processing unit execution. Using our approach we perform registration of T1-weighted MR images in less than 1min and show the same level of accuracy as a classical serial implementation when performing segmentation propagation. This technology could be of significant utility in time-critical applications such as image-guided interventions, or in the processing of large data sets. (C) 2009 Elsevier Ireland Ltd.
