Curated BUSI dataset - Curated Breast Ultrasound Images

The Curated BUSI dataset is a post-processed version presented in [2] of the original Breast Ultrasound Images (BUSI) dataset [1]. 

The original BUSI dataset consists of 780 breast ultrasound images collected from female patients aged 25–75 years, annotated for three classes (normal, benign, malignant) with corresponding segmentation masks for the lesions. Although widely used, the original BUSI dataset contains significant data quality issues, including duplicate images, inconsistent class labels, and annotation discrepancies, which can bias model training and evaluation.

To address these issues, Aumente-Maestro et al. (2025) curated the BUSI dataset by applying an automated duplicate detection algorithm followed by manual review to remove repeated and problematic cases. The resulting Curated BUSI dataset contains images with more reliable labels and segmentation masks, reducing the bias present in the original dataset and enabling more robust development and evaluation of machine learning models for breast ultrasound analysis.
