2011 2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society  
In this work we propose to initialize our previously introduced model based 3D level set esophagus segmentation method with a principal curve tracing (PCT) algorithm, which we adapted to solve the esophagus  ...  Our results show improvement in esophagus segmentation when initialized by PCT compared to our previous work, where an ad hoc centerline initialization was performed.  ...  We initialize our 3D level set segmentation algorithm from this PCT centerline estimate.  ...
