Methods and Materials: We collected 606 esophageal cancer patients from four institutions. 252 institution-1 patients had a treatment planning-CT (pCT) and a pair of diagnostic FDG-PETCT; 354 patients  ...  The current clinical workflow for esophageal gross tumor volume (GTV) contouring relies on manual delineation of high labor-costs and interuser variability.  ...  Fig. 2 . 2 The two-streamed 3D deep learning model for esophageal gross tumor volume (GTV) segmentation using treatment planning CT (pCT) and FDG-PET/CT scans. pCT stream takes the pCT as input and produces  ...

Clinical target volume (CTV) is defined as the gross tumor and intraductal component detected by MRI images.  ...  Three-field C-ion beams with 290 MeV/n energy are used by means of passive broad beam methods using individual collimators and a compensation bolus absorber.  ...  Fusion of PETCT with Planning CT permits to reduce the planning target volume according to the activity of the tumor rather than to define the volumes with anatomy only.  ...
