Abstract: Highlights•Bolus segmentation model based on preprocessing ensemble and cascaded inference.•Preprocessing ensemble network to enhance VFSS image in contrast and sharpness.•Cascaded inference network to reduce ambiguity in bolus segmentation using contexts.•PECI-Net outperformed four existing models in bolus segmentation by large margins.
