Atlas-guided generation of pseudo-CT images for MRI-only and hybrid PET-MRI-guided radiotherapy treatment planning
TL;DR: A two-step (segmentation and fusion) atlas-based algorithm focusing on bone tissue identification to create a pseudo-CT image from conventional MRI sequences with improved bone extraction accuracy is proposed and is promising for potential use in PET AC and MRI-only or hybrid PET/MRI-guided RT treatment planning.
Journal ArticleDOI
Comparative study of algorithms for synthetic CT generation from MRI: Consequences for MRI-guided radiation planning in the pelvic region.
Hossein Arabi,Jason Dowling,Ninon Burgos,Xiao Han,Peter B. Greer,Nikolaos Koutsouvelis,Habib Zaidi +6 more
TL;DR: Machine learning and advanced atlas-based methods exhibited promising performance by achieving reliable organ segmentation and synthetic CT generation and the challenge of electron density estimation from MR images can be resolved with a clinically tolerable error.
Journal ArticleDOI

Conde-Moreno,Felipe Couñago,F. Vanhoutte,Els Goetghebeur,Dries Reynders,Thomas Zilli,Piet Ost +25 more
TL;DR: This is the first prospective multicentre randomized phase II trial assessing the potential of combined WPRT and MDT as compared to MDT alone on MFS for patients with nodal oligorecurrent PCa.
Journal ArticleDOI

TL;DR: Aim of this paper is to present the phase I results of a 19 Gy single fraction urethra-sparing SBRT with real-time electromagnetic tracking.
Journal ArticleDOI
Comparison of the incidence of osteoradionecrosis with conventional radiotherapy and intensity‐modulated radiotherapy
Thibault De Maesschalck,Nicolas Dulguerov,Francesca Caparrotti,Paolo Scolozzi,Cristina Picardi,Nicolas Mach,Nikolaos Koutsouvelis,Pavel Dulguerov +7 more
TL;DR: In this paper, the authors compared the incidence of osteoradionecrosis of the mandible after intensity-modulated radiotherapy (IMRT) in comparison to conventional 3D conformal radiotherapy techniques (conventional RT).
