Rapid CNN-based needle localization for automatic slice alignment in MR-guided interventions using 3D undersampled radial white-marker imaging

CONCLUSION: The investigated approach enables passive biopsy needle localization in 3D. Acceleration of the localization to real-time applicability is feasible for needle orientations approximately perpendicular to B(0). The method can potentially facilitate MR-guided needle interventions by enabling automatic imaging slice alignment with the …
