我们提出了一个高度并行的方法,准确和高效的消费级图形处理单元(GPU)上的变分变形3D图像配准。我们建立在最近的无矩阵变分方法和专门的概念,以并行的多核架构的GPU提供的。与并行和优化的CPU实现相比,这使我们能够在986次真实CT胸腹随访扫描中实现32:53的平均加速比。在大约2563体素的分辨率下,完整配准的平均运行时间为1:99秒。在公开的DIR实验室基准测试中,我们的方法在平均运行时间0:32秒时的平均地标误差方面排名第三。
We present a highly parallel method for accurate and efficient variational deformable 3D image registration on a consumer-grade graphics processing unit (GPU). We build on recent matrix-free variational approaches and specialize the concepts to the massively-parallel manycore architecture provided by the GPU. Compared to a parallel and optimized CPU implementation, this allows us to achieve an average speedup of 32:53 on 986 real-world CT thorax-abdomen follow-up scans. At a resolution of approximately 2563 voxels, the average runtime is 1:99 seconds for the full registration. On the publicly available DIR-lab benchmark, our method ranks third with respect to average landmark error at an average runtime of 0:32 seconds.
