An Expert-Annotated Dataset of Bone Marrow Cytology in Hematologic Malignancies

The dataset contains a collection of over 170,000 de-identified, expert-annotated cells from the bone marrow smears of 945 patients stained using the May-Grünwald-Giemsa/Pappenheim stain. The diagnosis distribution in the cohort included a variety of hematological diseases reflective of the sample entry of a large laboratory specialized in leukemia diagnostics. Image acquisition was performed using a brightfield microscope with 40x magnification and oil immersion.

本数据集收录了来自945名患者骨髓涂片的17万余张经去标识化（de-identified）、专家标注的细胞显微图像，所有样本均采用梅-格-吉（May-Grünwald-Giemsa）/帕彭海姆（Pappenheim）染色法进行染色。该研究队列的诊断分布涵盖多种血液系统疾病，其样本来源自一家专注于白血病诊断的大型实验室，契合该类专业实验室的样本收录特征。图像采集采用明场显微镜（brightfield microscope），以40倍放大倍率搭配油浸物镜完成。
