A synthetic data pipeline that inserts anatomy-guided shapes and cut-paste objects into chest X-rays trains foreign-object segmentation models to match fully supervised performance with 93 percent fewer manual masks.
We integrate expert knowledge by plotting structures that models either generalize from or can directly find as a target
