SA-Med2D-20M

Image

The largest benchmark dataset for segmentation in the field of medical imaging.

As is well known, the emergence of ImageNet has greatly propelled the development of AI, especially deep learning. It has provided massive data and powerful baseline models for the computer vision community, enabling researchers to achieve breakthroughs in tasks such as natural image classification, segmentation, and detection. However, in the medical image realm, there lack of such a large dataset for developing powerful medical models.

To address the gap in the medical field, we are introducing the largest benchmark dataset for medical image segmentation. This initiative aims to drive the rapid development of AI in healthcare and accelerate the transformation of computational medicine towards a more inclusive direction.

Please visit the GitHub page and further exploit the dataset!

Due to data privacy and ethical requirements, we currently only provide access to a 16M dataset. We will keep updating and maintaining this database. Please stay tuned for further updates from us.

The SA-Med2D-20M dataset is named following the convention below:

-images
  -{modality_sub-modality}--{dataset name}--{ori name}--{dimension_slice}.png

-masks
  -{modality_sub-modality}--{dataset name}--{ori name}--{dimension_slice}--{class instance_id}.png

Note: "sub-modality" applies only to 3D data, and when "sub-modality" is "00," it indicates either the absence of a sub-modality or an unknown sub-modality type. "dataset name" refers to the specific dataset name that the case is from. "ori name" is the original case name in its dataset. "dimension slice", e.g., "x_100", indicates the dimension along which we split a 3D case as well as the slice ID in this dimension. If we split a 3D case with axis x and the current slice is 100, then the term can be "x_0100". For 2D datasets, the "dimension_slice id" is uniformly set to "2d_none". "class instance_id", unique to masks, encapsulates both category information and instance id, and the detailed information is stored in the "SAMed2D_v1_class_mapping_id.json" file. For instance, if the category "liver" is assigned the ID "0003" and there is only one instance of this category in the case, the "class instance_id" can be denoted as "0003_000". Besides, the category "liver" in the "SAMed2D_v1_class_mapping_id.json" file is formulated as key-value pair with python-dict format: {"liver": "0003"}.

The file "SAMed2D_v1_class_mapping_id.json" stores the information for converting class instances. The file "SAMed2D_v1.json" contains the path information for all image and mask pairs.
