GlaS Dataset

The dataset used in this challenge consists of 165 images derived from 16 H&E stained histological sections of stage T3 or T42 colorectal adenocarcinoma. Each section belongs to a different patient, and sections were processed in the laboratory on different occasions. Thus, the dataset exhibits high inter-subject variability in both stain distribution and tissue architecture. The digitization of these histological sections into whole-slide images (WSIs) was accomplished using a Zeiss MIRAX MIDI Slide Scanner with a pixel resolution of 0.465µm.

本挑战所使用的数据集由来自16张T3或T4期结直肠癌H&E染色组织切片的165幅图像构成。每一切片均来自不同患者，且切片在实验室的不同时间进行处理。因此，该数据集在染色分布和组织结构方面均表现出较高的个体间差异性。这些组织切片经过数字化处理生成全切片图像（WSI），所采用的设备为配备0.465µm像素分辨率的蔡司MIRAX MIDI切片扫描仪。
