Keywords: Myocardium, SegmentationObtaining databases with expert’ manual segmentations to train U-Net is an essential but also a time-consuming operation. We explore here the effect of expanding such a database to other cases with a demon co-registration algorithm. The purpose is to speed up the manual steps but also to allow the development of segmentation algorithms for new cases. We illustrate our approach with MOLLI’ masks expanded to T2 and perfusion data.
