Progressive Prompting for Robust Segmentation
RPFeaNet introduces three core components designed to overcome the inherent challenges of ultrasound imaging: speckle noise, low contrast, and boundary ambiguity. The Progressive Prompt Generation Module (PPGM) enriches multi-level spatial prior information, guiding the model to understand image characteristics from low to high levels. The High-Level Prompt-Guided Feature Interaction Module (HPGFIM) leverages Mamba blocks and stage-wise conditioning to fuse progressive prompts with backbone features, focusing on essential shape and texture. Finally, the Dynamic Selective-Frequency Decoder (DSFD) combines dynamic frequency selection with high-frequency detail fusion to suppress noise and refine edge details, delivering sharp and accurate segmentation boundaries.
Advanced Architecture: Mamba, Frequency, and Multi-level Priors
The innovation in RPFeaNet stems from its sophisticated integration of advanced AI components. The progressive prompt generation involves a hierarchical elevation that mines multi-level spatial priors from frozen CLIP encoders (low-level structural), patch-level encoders (middle-level dense), and SAM2's hierarchical features (high-level semantic). This creates a coherent prior system for ultrasound images. The HPGFIM utilizes Visual Mamba (SS2D) blocks for efficient and effective feature interaction, tailored to capture intricate shape and texture features. The DSFD employs a frequency-decomposed gating mechanism to dynamically select frequency transformations, enhancing the ability to convert high-level semantic features into low-level details for precise boundary recovery.
Unparalleled Accuracy Across Diverse Datasets
Extensive experiments on six benchmark datasets (CCAUI, CAMUS, DDTI, TN3K, HC-18, JNU-IFM) validate RPFeaNet's superior performance over state-of-the-art methods. On cardiac datasets (CCAUI, CAMUS), RPFeaNet achieved an average performance gain of 10% across Jaccard, Dice, ASSD, and MSE metrics, and maintained superior stability with the smallest standard deviations. For challenging thyroid nodule boundaries (TN3K), Dice coefficients increased by 1.4% to 1.2%, and ASSD was drastically reduced by 21.1%, demonstrating exceptional robustness. The model consistently provides more accurate and visually smooth segmentation contours, even in the presence of severe noise and blurred edges.
Considerations for Enterprise Deployment
While RPFeaNet demonstrates strong performance, certain limitations should be considered. Its generalization to niche clinical use cases and underrepresented imaging scenarios requires further verification. The fixed 256x256 input size may result in a loss of fine-grained details for very small lesions in high-resolution ultrasound images. Additionally, the Mamba-based SS2D blocks, while parameter-efficient, rely on sequential selective scan operations which are inherently less parallelizable than traditional CNN convolutions or Transformer self-attention, potentially impacting computational efficiency in scenarios requiring extreme parallelism.

Case Study: Overcoming Ultrasound Image Degradation
Challenge: Ultrasound images are inherently degraded by speckle noise, low contrast, and artifacts such as acoustic shadows, leading to ambiguous lesion boundaries and significantly increased segmentation difficulty. Traditional methods often struggle to maintain stability for low-saliency objects, small targets, and weak boundaries.
RPFeaNet Solution: Our framework directly tackles these challenges. The Progressive Prompt Generation Module provides stable, multi-level spatial guidance that refines structural priors. The High-Level Prompt-Guided Feature Interaction Module, powered by Mamba blocks, effectively captures target shape and texture features. Crucially, the Dynamic Selective-Frequency Decoder intelligently selects and fuses frequency information to suppress noise and precisely refine edges. This integrated approach enables RPFeaNet to achieve superior accuracy and robustness in delineating complex anatomical structures, even under adverse imaging conditions, ensuring higher diagnostic confidence and patient safety.
