Abstract: The present disclosure provides a computer-implemented method, a device, and a storage medium. The method includes inputting an image into an attention-enhanced high-resolution network (AHRNet) to extract feature maps for generating a first feature map; generating a first probability map which is concatenated with the first feature map to form a concatenated first feature map, and updating the AHRNet using the first segmentation loss; generating a second feature map, and scaling the second feature map to form a third feature map; generating a second probability map which is concatenated with the third feature map to form a concatenated third feature map, and updating the AHRNet using the second segmentation loss; generating a fourth feature map, and scaling the fourth feature map to form a fifth feature map; updating the AHRNet using the third segmentation loss and the regional level set loss; and outputting the third probability map.

Abstract: The present disclosure provides a method, a device, and a computer program product using a self-supervised anatomical embedding (SAM) method.

Abstract: The present disclosure provides a method, a device, and a storage medium for prior-guided dual-path network (PDNet). The method includes inputting an image into a split-attention network to extract a feature map at each scale and compressing the feature map to form a compressed feature map of each scale, by an image encoder, inputting the compressed feature map and a three-channel image into a prior encoder to generate an attention enhanced feature map of each scale, and outputting the attention enhanced feature map to a decoder; concatenating, by the decoder, an attention enhanced feature map at a current scale, in combination with up-sampled feature maps and/or down-sampled feature maps from other scales, to form a concatenated feature map of the current scale; and attaching a deconvolutional layer to a highest-level scale SA to segment a lesion and predict a RECIST diameter based on concatenated feature maps.
