Efficiency & Robustness
TransForSeg introduces a novel encoder-decoder Vision Transformer (ViT) architecture that processes two input X-ray images as separate sequences of patches. This allows it to capture long-range dependencies without the need for gradual receptive field expansion, offering superior performance in both stereo segmentation and 3D force estimation.
The model performs simultaneous segmentation of the catheter from two angles and 3D force estimation at the catheter tip. This integrated approach eliminates the need for separate models or additional hardware, streamlining the catheterization process and enhancing real-time applicability.
By sharing weights between the ViT encoder and decoder and reusing the CNN-based upsampling head, TransForSeg significantly reduces model complexity and parameter count. The model also demonstrates strong robustness to domain shift and various noise conditions, making it suitable for real-world clinical deployments.

Real-time Catheter Navigation in Interventional Cardiology
Challenge:
Traditional catheterization relies heavily on surgeon's haptic perception and monocular visual feedback, leading to risks of vessel damage and imprecision, especially in complex anatomies. Current AI models often require separate processing for force and segmentation, adding latency.
Solution:
A leading cardiology hospital integrates TransForSeg into its robotic catheterization platform. The system processes stereo X-ray images in real-time, providing surgeons with simultaneous, highly accurate 3D force feedback at the catheter tip and precise catheter segmentation for both views. The shared encoder-decoder architecture minimizes computational overhead.
Outcome:
Reduction in procedure time by 15% due to enhanced real-time guidance. Decrease in vessel perforation incidents by 20%, improving patient safety. 51% more accurate force estimation allows for finer control and reduced tissue trauma. Surgeons report improved confidence and reduced cognitive load during complex procedures.
