Feasibility of using a novel automatic cardiac segmentation algorithm in the clinical routine of lung cancer patients
Fig 5
Examples of results from our proposed automatic heart segmentation method (blue), compared to manual contouring (red), shown here for the best (top), median (middle) and worst (bottom) performing patient image sets, as ranked using the mean absolute surface-to-surface distance (MASD).
We display each binned respiratory phase image, 0% - 90% in 10% increments going left to right. Overall, our method provides consistently accurate delineations. Some variations from manual contouring can be seen, for example in the 60% in the bottom row, where deviations in manual contouring can be seen on the borders of the heart.
