Radiation therapy planning can benefit from the superior
display of soft tissue contrasts and the delineation of
tumor and critical organs in magnetic resonance imaging.
In this study, an advanced approach on the basis of
Dixon MR techniques with subsequent reconstruction
workflow is introduced for soft tissue and bone
classification in order to generate MR-derived simulated
computed tomography (CT) maps. For the first time, this
method is evaluated in patients with corresponding true
CT data and radiation therapy plans.
