视网膜色素变性病变区域分割数据集

该数据集供课题三元学习自推断医学影像诊断系统的眼科影像数据分类与分割部分使用 数据集内容:150例RP患者的301张眼底彩照图像和800张正常的眼底彩照图像。 数据来源:由沈阳何氏眼科医院提供，使用设备为DRS眼底照相机。 采集地点与时间:2022沈阳何氏眼科医院。 采集方案：使用DRS眼底照相机对患者进行影像采集，整个过程严格按照医学影像数据采集规范，挑选确诊为视网膜色素变性的RP患者，并纳入部分正常眼底患者作为对照组，确保数据的对比性和代表性。在暗光环境下进行拍摄，调整设备参数以优化成像质量。通过DRS眼底照相机对每位患者的眼底进行多角度、多区域的拍摄，捕捉病变区域的详细特征。影像以JPEG格式保存，并记录对应的患者编号、病史信息及影像拍摄参数。对采集图像进行分组标注，RP患者的眼底图像作为病变组，正常患者的眼底图像作为对照组，确保分割模型训练的有效性。影像采集完成后，由眼科专家进行检查，剔除模糊或干扰影像。眼底彩照保存为JPEG格式，记录了病变区域的详细特征及眼底整体结构信息。 设备说明：使用的DRS眼底照相机具有高分辨率和广视野特性，为视网膜病变区域的精准分割提供了可靠的数据基础。This dataset is intended for the classification and segmentation subtasks of ophthalmic imaging data in a triplet learning-based inferential medical image diagnosis system for research projects. Dataset Content: A total of 301 color fundus photographs from 150 patients with retinitis pigmentosa (RP) and 800 color fundus photographs from healthy individuals. Data Source: Provided by Shenyang He Eye Hospital, with images captured using DRS fundus cameras. Collection Location and Time: Shenyang He Eye Hospital, 2022. Collection Protocol: The DRS fundus cameras were used to acquire images from participants, with the entire process strictly following medical imaging data collection standards. Patients diagnosed with retinitis pigmentosa (RP) were included as the case group, while healthy participants with normal fundus were recruited as the control group to ensure data comparability and representativeness. Imaging was performed in a dim environment, with device parameters adjusted to optimize imaging quality. Multi-angle and multi-region fundus imaging was conducted for each participant to capture detailed features of lesion regions. All images were saved in JPEG format, with corresponding patient identification numbers, medical history information, and imaging capture parameters recorded. Collected images were grouped and annotated: fundus images from RP patients were categorized as the lesion group, while those from healthy participants were categorized as the control group, to guarantee the effectiveness of segmentation model training. Upon completion of image collection, ophthalmologists performed inspections to eliminate blurry or interfering images. The color fundus photographs, saved in JPEG format, record both the detailed features of lesion areas and the overall structural information of the fundus. Equipment Description: The employed DRS fundus cameras feature high resolution and wide field of view, providing a reliable data foundation for precise segmentation of retinal lesion regions.
