Query: Population-based Respiratory 4D Motion Atlas Construction and its
  Application for VR Simulations of Liver Punctures   Virtual reality (VR) training simulators of liver needle insertion in the
hepatic area of breathing virtual patients currently need 4D data acquisitions
as a prerequisite. Here, first a population-based breathing virtual patient 4D
atlas can be built and second the requirement of a dose-relevant or expensive
acquisition of a 4D data set for a new static 3D patient can be mitigated by
warping the mean atlas motion. The breakthrough contribution of this work is
the construction and reuse of population-based learned 4D motion models.
