Mammogram Image Dataset for Breast Cancer Detection

The dataset was retrospectively compiled following approval from the relevant Institutional Review Board (IRB) or Ethics Committee. Data were sourced from de-identified patient biopsy records at a tertiary hospital, encompassing a defined collection window from January 1, 2023, to October 31, 2023. The dataset comprises 614 original ((361 benign and 253 malignant cases)) breast X-ray images (mammograms) sourced exclusively from a single institution: a hospital in Polokwane, Limpopo, South Africa. All images have been clinically validated to establish the ground truth by a panel of radiologists and specialized medical practitioners. The acquisition process utilized a dedicated breast X-ray system equipped with specialized accessories to minimize radiation exposure, adhering to safety protocols. All data is standardized in the PNG format with a uniform resolution of 1920 × 1080 pixels.本数据集经相关机构审查委员会（Institutional Review Board，IRB）或伦理委员会批准后进行回顾性汇编。数据来源于南非林波波省波罗克瓦尼的一家三级医院的去标识化患者活检档案，采集周期明确设定为2023年1月1日至2023年10月31日。本数据集共包含614张原始乳腺X线摄影（mammograms）图像，其中良性病例361例、恶性病例253例，所有图像均仅来自该单一家医院。所有图像均经由放射科医师及专科医疗人员组成的专家组临床验证，以确立其真值标签。图像采集过程采用配备专用配件的专用乳腺X线摄影系统，以最大限度降低辐射暴露，并严格遵循安全操作规范。所有数据均标准化为PNG格式，统一分辨率为1920×1080像素。
