Generating 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 کاملMR-guided multi-atlas based synthetic CT for MR-only radiotherapy of head and neck cancer patients
S71 ______________________________________________________________________________________________________ provided by dual-energy CT (DECT) compared to singleenergy CT (SECT) can be clinically used to reduce CT-based range uncertainties and to analyze intraand interpatient tissue variations. First, a DECT scan protocol was optimized and clinically introduced. Second, in a first analysis patien...
متن کاملMR-based synthetic CT generation using a deep convolutional neural network method.
PURPOSE Interests have been rapidly growing in the field of radiotherapy to replace CT with magnetic resonance imaging (MRI), due to superior soft tissue contrast offered by MRI and the desire to reduce unnecessary radiation dose. MR-only radiotherapy also simplifies clinical workflow and avoids uncertainties in aligning MR with CT. Methods, however, are needed to derive CT-equivalent represent...
متن کاملComparison 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 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...
