We developed a suite of pre-trained 3D models, named SuPreM, that combined the best of large-scale datasets and per-voxel annotations, showing the transferability across a range of 3D medical imaging tasks.

An Extensive Dataset: AbdomenAtlas 1.1

The release of AbdomenAtlas 1.0 can be found at https://huggingface.co/datasets/AbdomenAtlas/AbdomenAtlas1.0Mini

AbdomenAtlas 1.1 is an extensive dataset of 9,262 CT volumes with per-voxel annotation of 25 organs and pseudo annotations for seven types of tumors, enabling us to finally perform supervised pre-training of AI models at scale. Based on AbdomenAtlas 1.1, we also provide a suite of pre-trained models comprising several widely recognized AI models.

Prelimianry benchmark showed that supervised pre-training strikes as a preferred choice in terms of performance and efficiency compared with self-supervised pre-training.

We anticipate that the release of large, annotated datasets (AbdomenAtlas 1.1) and the suite of pre-trained models (SuPreM) will bolster collaborative endeavors in establishing Foundation Datasets and Foundation Models for the broader applications of 3D volumetric medical image analysis.

The AbdomenAtlas 1.1 dataset is organized as

A Suite of Pre-trained Models: SuPreM

The following is a list of supported model backbones in our collection. Select the appropriate family of backbones and click to expand the table, download a specific backbone and its pre-trained weights (name and download), and save the weights into ./pretrained_weights/. More backbones will be added along time. Please suggest the backbone in this channel if you want us to pre-train it on AbdomenAtlas 1.1 containing 9,262 annotated CT volumes.
