Breast MRI segmentation for density estimation: Do different methods give the same results and how much do differences matter?
Doran, SJ; Hipwell, JH; Denholm, R; Eiben, B; Busana, M; et al. (WILEY, 2017-09-01)PURPOSE: To compare two methods of automatic breast segmentation with each other and with manual segmentation in a large subject cohort. To discuss the factors involved in selecting the most appropriate algorithm for ... -
Consistent and invertible deformation vector fields for a breathing anthropomorphic phantom: a post-processing framework for the XCAT phantom.
Eiben, B; Bertholet, J; Menten, MJ; Nill, S; Oelfke, U; et al. (IOP PUBLISHING LTD, 2020-08-13)Breathing motion is challenging for radiotherapy planning and delivery. This requires advanced four-dimensional (4D) imaging and motion mitigation strategies and associated validation tools with known deformations. Numerical ... -
Evaluation of MRI-derived surrogate signals to model respiratory motion.
Tran, EH; Eiben, B; Wetscherek, A; Oelfke, U; Meedt, G; et al. (IOP PUBLISHING LTD, 2020-07-01)An MR-Linac can provide motion information of tumour and organs-at-risk before, during, and after beam delivery. However, MR imaging cannot provide real-time high-quality volumetric images which capture breath-to-breath ... -
Real-time intrafraction motion monitoring in external beam radiotherapy.
Bertholet, J; Knopf, A; Eiben, B; McClelland, J; Grimwood, A; et al. (IOP PUBLISHING LTD, 2019-08-07)Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is constantly moving due to respiratory, ... -
Respiratory motion modelling for MR-guided lung cancer radiotherapy: model development and geometric accuracy evaluation.
Eiben, B; Bertholet, J; Tran, EH; Wetscherek, A; Shiarli, A-M; et al. (IOP Publishing Ltd, 2024-02-19)Objective.Respiratory motion of lung tumours and adjacent structures is challenging for radiotherapy. Online MR-imaging cannot currently provide real-time volumetric information of the moving patient anatomy, therefore ... -
Tumour auto-contouring on 2d cine MRI for locally advanced lung cancer: A comparative study.
Fast, MF; Eiben, B; Menten, MJ; Wetscherek, A; Hawkes, DJ; et al. (ELSEVIER IRELAND LTD, 2017-12-01)BACKGROUND AND PURPOSE: Radiotherapy guidance based on magnetic resonance imaging (MRI) is currently becoming a clinical reality. Fast 2d cine MRI sequences are expected to increase the precision of radiation delivery by ...
