Medical Instrument Detection in Ultrasound-Guided Interventions: A Review

no code implementations9 Jul 2020 Hongxu Yang, Caifeng Shan, Alexander F. Kolen, Peter H. N. de With

Medical instrument detection is essential for computer-assisted interventions since it would facilitate the surgeons to find the instrument efficiently with a better interpretation, which leads to a better outcome.

Deep Q-Network-Driven Catheter Segmentation in 3D US by Hybrid Constrained Semi-Supervised Learning and Dual-UNet

no code implementations25 Jun 2020 Hongxu Yang, Caifeng Shan, Alexander F. Kolen, Peter H. N. de With

To train the Dual-UNet with limited labeled images and leverage information of unlabeled images, we propose a novel semi-supervised scheme, which exploits unlabeled images based on hybrid constraints from predictions.
