Architecture Analysis and Benchmarking of 3D U-shaped Deep Learning Models for Thoracic Anatomical Segmentation

1 code implementation5 Feb 2024 Arash Harirpoush, Amirhossein Rasoulian, Marta Kersten-Oertel, Yiming Xiao

We conduct the first systematic benchmark study for variants of 3D U-shaped models (3DUNet, STUNet, AttentionUNet, SwinUNETR, FocalSegNet, and a novel 3D SwinUnet with four variants) with a focus on CT-based anatomical segmentation for thoracic surgery.

Weakly supervised segmentation of intracranial aneurysms using a novel 3D focal modulation UNet

1 code implementation6 Aug 2023 Amirhossein Rasoulian, Arash Harirpoush, Soorena Salari, Yiming Xiao

In the paper, we propose FocalSegNet, a novel 3D focal modulation UNet, to detect an aneurysm and offer an initial, coarse segmentation of it from time-of-flight MRA image patches, which is further refined with a dense conditional random field (CRF) post-processing layer to produce a final segmentation map.

Towards multi-modal anatomical landmark detection for ultrasound-guided brain tumor resection with contrastive learning

no code implementations26 Jul 2023 Soorena Salari, Amirhossein Rasoulian, Hassan Rivaz, Yiming Xiao

Specifically, two convolutional neural networks were trained jointly to encode image features in MRI and US scans to help match the US image patch that contain the corresponding landmarks in the MRI.

In brain tumor resection, accurate removal of cancerous tissues while preserving eloquent regions is crucial to the safety and outcomes of the treatment.

Weakly Supervised Intracranial Hemorrhage Segmentation using Head-Wise Gradient-Infused Self-Attention Maps from a Swin Transformer in Categorical Learning

1 code implementation11 Apr 2023 Amirhossein Rasoulian, Soorena Salari, Yiming Xiao

With a mean Dice score of 0. 44, our technique achieved similar ICH segmentation performance as the popular U-Net and Swin-UNETR models with full supervision and outperformed a similar weakly supervised approach using GradCAM, demonstrating the excellent potential of the proposed framework in challenging medical image segmentation tasks.
