2) Transformer的局部感应偏置不足会影响对模糊边界等细节特征的分割能力。因此,要将Vision Transformer机制应用于医学图像分割领域,需要充分克服上述挑战。 宾夕法尼亚大学的Jayaram团队提出了可变形状混合Transformer(VSmTrans),它集成了自注意和卷积,可以从自注意机制中学习复杂关系,也可以从卷积中学习局部先验知识。具体...

此外, Swin Transformers 的层次性使其非常适合需要多尺度建模的任务。 继领先的 UNETR 模型成功使用直接使用 3D 补丁嵌入的基于 ViT 的编码器之后, Swin UNETR 使用了具有金字塔结构的 3D Swin transformer 编码器。 在Swin UNETR 的编码器中,由于计算简单的全局自我注意对于高分辨率特征地图是不可行的,因此在本地...

To tackle these limitations, we propose a novel self-supervised learning framework for 3D medical image analysis. First, we propose a new architecture dubbed Swin UNEt TRansformers (Swin UNETR) with a Swin Transformer encoder that directly utilizes 3D input patches. Subsequently, the transformer encod...
Inspired by these results, we introduce a novel self-supervised learning framework with tailored proxy tasks for medical image analysis. Specifically, we propose: (i) a new 3D transformer-based model, dubbed Swin UNEt TRansformers (Swin UNETR), with a hierarchical encoder for self-supervised pre-...
The technology behind Swin UNETR Swin Transformers adopts a hierarchical Vision Transformer (ViT) for local computing of self-attention with nonoverlapping windows. This unlocks the opportunity to create a medical-specific ImageNet for large companies and removes the bottleneck of ne...
