Documentation of complex pathologies requires fast and easy assessment of all findings. To acquire information from large body regions, large fields-of-view (FOV) and multi-channel coils must be applied. Images with large FOV can also be characterized by inhomogeneous illumination, potentially more pronounced at higher field strengths. Therefore, a simple applicable and robust post-processing approach is required to improve signal homogeneity, consequently avoiding manual adjustments. In their article, Jellus et al. provide background information about filtering implemented in syngo composing software.
