The 26 full workshop papers included in this book were carefully reviewed and selected from 32 submissions. The CMRxRecon Challenge received 22 paper submissions of which 8 are included in this book. They deal with cardiac segmentation, modelling, motion estimation, statistical shape analysis, and quality control. Deep learning methods were still the predominant approach to performing automated cardiac image analysis. Left atrial image analysis and modelling gained more attention in this workshop, with atrial fibrillation being the common area of interest.
