摘要
Abstract
To address the issues of noise interference,low contrast,and blurred boundaries in thyroid nod-ule ultrasound images,an improved SAMUS was constructed based on the SAMUS framework.This model employs a shallow feature extraction module to obtain multi-scale detail information and intro-duces a shallow feature fusion strategy in the decoding stage to supplement shallow representations and enhance adaptability to morphological changes of nodules.A comparative experiment conducted between the improved SAMUS and four traditional models shows that compared with the U-Net,U-Net v2,DAE-Former and SAMUS,the improved SAMUS can more accurately restore the target shape,effectively re-duce mis-segmentation and under-segmentation phenomena;compared with the SAMUS,the IOU of the improved SAMUS increases by 0.89,the Dice increases by 0.73,and the HD95 decreases by 0.30.This indicates that the improved SAMUS can obtain shallow multi-scale detailed features and fuse them dur-ing the decoding stage,which can improve the overlap degree of thyroid nodule image segmentation and reduce boundary errors.关键词
