A phantom study to create synthetic CT from orthogonal twodimensional cine MRI and evaluate the effect of irregular breathing

Autor: Chiara Paganelli, Paul J. Keall, Marco Muller

Publikováno v: EMBC

An exciting innovation in radiotherapy is the use of real-time MRI for treatment adaptation. This study proposes an in-silico framework for the generation of 3D synthetic CT (sCT) from orthogonal interleaved 2D cine MRI data to overcome the lack of e

Image-based retrospective 4D MRI in external beam radiotherapy: A comparative study with a digital phantom

Autor: John Kipritidis, Guido Baroni, Chiara Paganelli, Danny Lee, Marco Riboldi, Paul J. Keall

Purpose Several image-based retrospective sorting methods of 4D magnetic resonance imaging (4D MRI) have been proposed for respiratory motion reconstruction in external beam radiotherapy. However, the optimal strategy for providing accurate and artif
