Automatic contour propagation along the motion states dimension in the

Download scientific diagram | Automatic contour propagation along the motion states dimension in the MIM software. Three contours (red: GTV, blue: duodenum-stomach, green: small bowel) are defined in the first phase (P1) by radiation oncologists, followed by an automatic propagation to other phases (P2-P10) using deformable image registration. The size and shape of the GTV (red) remain relatively stable across the phases, while significant changes are observed from P1 to P10 for the duodenum-stomach (blue) and small bowel (green) due to respiratory motion. from publication: Real-time 4D MRI using MR signature matching (MRSIGMA) on a 1.5T MR-Linac system | Objective: To develop real-time 4D MRI using MR signature matching (MRSIGMA) for volumetric motion imaging in patients with pancreatic cancer on a 1.5T MR-Linac system. Approach: Two consecutive MRI scans with 3D golden-angle radial stack-of-stars acquisitions were performed | Motion Tracking, Magnetic Resonance Imaging and Real Time | ResearchGate, the professional network for scientists.
