Ultrasound high-resolution (HR) and low-resolution (LR) Hand arm Tissue image data (B-mode)
Description
Ultrasound B-Mode High-Resolution and Low-Resolution Hand/Arm Tissue Image Data. This dataset comprises grayscale B-mode ultrasound images of soft tissues in the human hand and forearm, captured under both high-resolution (HR) and low-resolution (LR) imaging conditions. The data is designed to support image enhancement, super-resolution, and tissue structure analysis tasks. High-Resolution (HR) Images: Acquired using wide-angle apertures (e.g., 75°) or high-frequency probes (>15 MHz). Provide superior spatial resolution with clear tissue boundaries, muscle layers, and skin-fat interfaces. Represent the target domain in image enhancement models. Low-Resolution (LR) Images: Captured using narrow-angle apertures (e.g., 1° to 15°) or low-frequency probes, or synthetically downsampled from HR images. Exhibit blurring, loss of anatomical detail, and reduced contrast. Serve as input for reconstruction or learning-based enhancement pipelines (e.g., TransCycleGAN, U-Net). The total has 42 .mat files. Each file has 100 Frames.
