abstract = {The suppression of motion artefacts from MR images is a
challenging task. The purpose of this paper was to develop a
standalone novel technique to suppress motion artefacts in
MR images using a data-driven deep learning approach. A
simulation framework was developed to generate
motion-corrupted images from motion-free images using
randomly generated motion profiles. An Inception-ResNet deep
learning network architecture was used as the encoder and
was augmented with a stack of convolution and upsampling
layers to form an encoder-decoder network. The network was
trained on simulated motion-corrupted images to identify and
suppress those artefacts attributable to motion. The network
was validated on unseen simulated datasets and real-world
experimental motion-corrupted in vivo brain datasets. The
trained network was able to suppress the motion artefacts in
the reconstructed images, and the mean structural similarity
(SSIM) increased from 0.9058 to 0.9338. The network was also
able to suppress the motion artefacts from the real-world
experimental dataset, and the mean SSIM increased from
0.8671 to 0.9145. The motion correction of the experimental
datasets demonstrated the effectiveness of the motion
simulation generation process. The proposed method
successfully removed motion artefacts and outperformed an
iterative entropy minimization method in terms of the SSIM
index and normalized root mean squared error, which were
$5–10\%$ better for the proposed method. In conclusion, a
novel, data-driven motion correction technique has been
developed that can suppress motion artefacts from
motion-corrupted MR images. The proposed technique is a
standalone, post-processing method that does not interfere
with data acquisition or reconstruction parameters, thus
making it suitable for routine clinical practice.},
