From: Breast tumor movements analysis using MRI scans in prone and supine positions
The origin of the bottom center of the sternum and the tumor center (red point) in 3D coordinates were obtained in the prone (A–C) and supine (D–F) positions. (A) The origin of the bottom center of the sternum (red point) was manually placed on coronal images. (B) The tumor center (yellow point) was evaluated through the center of gravity function and the distance from the tumor center to the chest wall was measured (red line). (C) The distance from the origin of the bottom center of the sternum to the tumor center were measured in 3D coordinates.
