Relational Reasoning Network (RRN) for Anatomical Landmarking

Abstract: Accurately identifying anatomical landmarks is a crucial step in deformation analysis and surgical planning for craniomaxillofacial (CMF) bones. Available methods require segmentation of the object of interest for precise landmarking. Unlike those, our purpose in this study is to perform anatomical landmarking using the inherent relation of CMF bones without explicitly segmenting them. We propose a new deep network architecture, called relational reasoning network (RRN), to accurately learn the local and the g… Show more

“…Nevertheless, their approach strongly relies on previous segmentation results and an underperformed outcome at this level would inevitably lead to inferior localization performance. To get rid of segmenting the regions of interest, a relational reasoning network is designed to infer other landmarks given locations of several representative ones (Torosdagli et al, 2019b). Although excellent localization results are obtained, the initial landmarks must be deliberately selected which limits the application in the real clinical setting.…”
