3D-EffiViTCaps: 3D Efficient Vision Transformer with Capsule for Medical Image Segmentation

Core Concepts
Proposing a U-shaped 3D-EffiViTCaps model combining capsule and EfficientViT blocks for improved medical image segmentation efficiency and performance.
Introduction to Medical Image Segmentation (MIS) Evolution of CNNs, Capsule Networks, and Transformers in MIS Proposal of 3D-EffiViTCaps model combining capsule and EfficientViT blocks Experiments on iSeg-2017, Hippocampus, and Cardiac datasets Comparison with SOTA models on different datasets Ablation study on different model components Loss functions used in training the model Visualization of segmentation results in iSeg-2017 dataset
"Our model performs better overall and on average with a considerable gap." "The average DSC has risen by 0.71%, and the segmentation performance of WM and GM has enhanced even more significantly." "For both datasets, 3D-EffiViTCaps has a greater advantage than the 3D Transformer-based SOTA 3D MIS model nnFormer."
"Our experiments show that it outperforms previous SOTA 3D CNN-based, 3D Capsule-based, and 3D Transformer-based models." "The segmentation results of our 3D-EffiViTCaps are quite similar to the ground truth."
