Comparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction
Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...
متن کاملDevelopment of MR-Only Planning for Prostate Radiation Therapy Using Synthetic CT
The department of Radiation Oncology at Calvary Mater Newcastle, treats approximately 1,800 new patients per year. When it comes to prostate treatments, MR scans are used in addition to CT for treatment planning. Having to undergo two scans however is a burden both to patients as well as the health system. We have looked into addressing this by replacing the CT by an MR-only workflow when treat...
متن کاملMR-OPERA: A Multicenter/Multivendor Validation of Magnetic Resonance Imaging-Only Prostate Treatment Planning Using Synthetic Computed Tomography Images.
PURPOSE To validate the dosimetric accuracy and clinical robustness of a commercially available software for magnetic resonance (MR) to synthetic computed tomography (sCT) conversion, in an MR imaging-only workflow for 170 prostate cancer patients. METHODS AND MATERIALS The 4 participating centers had MriPlanner (Spectronic Medical), an atlas-based sCT generation software, installed as a clou...
متن کاملGenerating the synthetic CT (sCT) and synthetic MR (sMR: sT1w/sT2w) images of the brain using atlas based method
Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...
متن کاملDosimetric evaluation of synthetic CT for magnetic resonance-only based radiotherapy planning of lung cancer
BACKGROUND Interest in MR-only treatment planning for radiation therapy is growing rapidly with the emergence of integrated MRI/linear accelerator technology. The purpose of this study was to evaluate the feasibility of using synthetic CT images generated from conventional Dixon-based MRI scans for radiation treatment planning of lung cancer. METHODS Eleven patients who underwent whole-body P...
