More Knowledge Is Better: Cross-Modality Volume Completion and 3D+2D Segmentation for Intracardiac Echocardiography Contouring
[chapter]
2018
Lecture Notes in Computer Science
Preserved Fulltext

However, it is a challenge to build an automatic contouring algorithm because ICE is noisy and provides only a limited 2D view of the 3D anatomy. ...
Experimental results show that our model is significantly better than a direct 2D image-to-image deep neural network segmentation, especially for less-observed structures. ...
It uses 3D geometry and cross-modality appearance knowledge for better anatomical understanding and structural consistency. ...

Conclusions: Real-time 3D binding sites assessment is feasible and improves transvenous lead extraction outcomes. ...
Results: CartoSound was able to detect more intracardiac binding sites compared to fluoroscopy (RA 17.4% vs. 4.3%, p = 0.04; RV 43.5% vs. 21.7%, p = 0.04), but was unable to assess the subclavian/innominate ...
