Core Concepts
Proposing a Spatial-Temporal Progressive Fusion Network (STPFNet) for accurate breast lesion segmentation in ultrasound videos.
Abstract
The article introduces the STPFNet, focusing on spatial-temporal fusion for lesion detection. It addresses challenges like blurred boundaries and irregular shapes in ultrasound data. The network utilizes a unified architecture capturing spatial and temporal dependencies. A Multi-Scale Feature Fusion module is proposed to enhance lesion detection by fusing spatial and temporal cues. The network leverages prior knowledge from previous frames to suppress noise and improve representation. A new dataset, UVBLS200, is introduced for breast lesion segmentation tasks with 200 videos containing benign and malignant lesions.
Stats
UVBLS200 dataset contains 200 videos with 80 benign and 120 malignant lesions.
STPFNet achieves better performance than state-of-the-art methods.
