The external body deformation caused a mean dose reduction of 0.6 ± 0.3 Gy, while the coverage reduced by 22% ± 13% and 27% ± 6% in V98 and V100, respectively. A dedicated MR simulation setup for prostate radiotherapy is essential to ensure the agreement between planning anatomy and treatment anatomy. The image signal was reduced after applying the coil mount, but no significant effect was found on prostate contouring.]]> Wed 11 Apr 2018 09:52:08 AEST ]]> MRI-guided prostate radiation therapy planning: investigation of dosimetric accuracy of MRI-based dose planning https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12469 Sat 24 Mar 2018 08:16:30 AEDT ]]> Does the planning dose-volume histogram represent treatment doses in image-guided prostate radiation therapy?: assessment with cone-beam computerised tomography scans https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12323 Sat 24 Mar 2018 08:11:36 AEDT ]]> Automatic MRI atlas-based external beam radiation therapy treatment planning for prostate cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11723 Sat 24 Mar 2018 08:07:24 AEDT ]]> Fast automatic multi-atlas segmentation of the prostate from 3D MR images https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17686 Sat 24 Mar 2018 07:57:43 AEDT ]]> A magnetic resonance imaging-based workflow for planning radiation therapy for prostate cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17685 Sat 24 Mar 2018 07:57:27 AEDT ]]> Treatment-related morbidity in prostate cancer: a comparison of 3-dimensional conformal radiation therapy with and without image guidance using implanted fiducial markers https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20180 Sat 24 Mar 2018 07:51:39 AEDT ]]> An atlas-based electron density mapping method for Magnetic Resonance Imaging (MRI)-alone treatment planning and adaptive MRI-based prostate radiation therapy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21552 p > 0.9) were found between CT and pseudo-CT Hounsfield units for organs of interest. Mean ± standard deviation DSC scores for the atlas-based segmentation of the pelvic bones were 0.79 ± 0.12, 0.70 ± 0.14 for the prostate, 0.64 ± 0.16 for the bladder, and 0.63 ± 0.16 for the rectum. Conclusions: The electron-density atlas method provides the ability to automatically define organs and map realistic electron densities to MRI scans for radiotherapy dose planning and DRR generation. This method provides the necessary tools for MRI-alone treatment planning and adaptive MRI-based prostate radiation therapy.]]> Sat 24 Mar 2018 07:50:23 AEDT ]]> MRI simulation: end-to-end testing for prostate radiation therapy using geometric pelvic MRI phantoms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27970 Sat 24 Mar 2018 07:38:43 AEDT ]]>
