Population-based respiratory 4D motion atlas construction and its application for VR simulations of liver punctures
A Mastmeyer, M Wilms… - Medical Imaging 2018 …, 2018 - spiedigitallibrary.org
Virtual reality (VR) training simulators of liver needle insertion in the hepatic area of
breathing virtual patients often need 4D image data acquisitions as a prerequisite. Here, first
a population-based breathing virtual patient 4D atlas is built and second the requirement of
a dose-relevant or expensive acquisition of a 4D CT or MRI data set for a new 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.
