44 Assessing the impact of key preprocessing concepts on the pseudo CT generation

Introduction. Magnetic Resonance Imaging (MRI) only radiotherapy workflows have been increasingly appealing as they ensure a reduction of the dose received by the healthy tissues and thus a higher patient safety. We used state-of-the-art 3D neural networks [1] to map any high-resolution T1-weighted MRI (T1) or enhanced T1 weighted MRI (T1Gd) to a pseudo Computed Tomography (pCT). The goal of this study was to quantify the impact of critical preprocessing steps on the 3D pCT generation.
