Abstract

Reconstruction of Computed Tomography (CT) images is a computationally and memory demanding tool. The creation of new algorithms for the reduction of the X-Ray dose and the increasing resolution of the detectors have complicated the obtaining of a good performance. Accelerators have become essential for the processing of the algorithm in a reasonable time. Nowadays, with the emergence of new mobile architectures that are not only powerful but also energy efficient and the possibility of easily porting the already existing code thanks to different programming models they could become an alternative to desktop and high performance accelerators. We evaluate four different platforms for our simulation framework for CT images. The evaluation results demonstrate that although in terms of performance, low-power platforms are still far from GPGPUs, the reduction of the energy consumption to almost a half in the case of the Jetson TK1 is an evident incentive that can lead to the creation of smaller and mobile medical image scanners.
