A phantom study to create synthetic CT from orthogonal twodimensional cine MRI and evaluate the effect of irregular breathing.
Published 2018-07-01An 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 ...Open AccessConference paper -
Image-based retrospective 4D MRI in external beam radiotherapy: A comparative study with a digital phantom.
Published 2018-07-01PURPOSE: 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 ...Open AccessArticle -
An in silico performance characterization of respiratory motion guided 4DCT for high-quality low-dose lung cancer imaging.
Published 2018-07-01This work aims to characterize the performance of an improved 4DCT technique aiming to overcome irregular breathing-related image artifacts. To address this, we have developed respiratory motion guided (RMG) 4DCT, which ...Open AccessArticle -
Feasibility study on 3D image reconstruction from 2D orthogonal cine-MRI for MRI-guided radiotherapy.
Published 2018-06-01INTRODUCTION: In-room MRI is a promising image guidance strategy in external beam radiotherapy to acquire volumetric information for moving targets. However, limitations in spatio-temporal resolution led several authors ...Open AccessArticle -
A CBCT study of the gravity-induced movement in rotating rabbits.
Published 2018-05-01Fixed-beam radiotherapy systems with subjects rotating about a longitudinal (horizontal) axis are subject to gravity-induced motion. Limited reports on the degree of this motion, and any deformation, has been reported ...Open AccessArticle
