An automated framework for brain vessel centerline extraction from CTA images

1 code implementation13 Jan 2024 Sijie Liu, Ruisheng Su, Jianghang Su, Jingmin Xin, Jiayi Wu, Wim van Zwam, Pieter Jan van Doormaal, Aad van der Lugt, Wiro J. Niessen, Nanning Zheng, Theo van Walsum

In this paper, we consider automatic lumen segmentation generation without additional annotation effort by physicians and more effective use of the generated lumen segmentation for improved centerline extraction performance.

AngioMoCo: Learning-based Motion Correction in Cerebral Digital Subtraction Angiography

no code implementations9 Oct 2023 Ruisheng Su, Matthijs van der Sluijs, Sandra Cornelissen, Wim van Zwam, Aad van der Lugt, Wiro Niessen, Danny Ruijters, Theo van Walsum, Adrian Dalca

This hinders the serial evaluation of blood flow, and often causes undesired vasculature and contrast flow alterations, leading to impeded usability in clinical practice.

Label Refinement Network from Synthetic Error Augmentation for Medical Image Segmentation

1 code implementation14 Sep 2022 Shuai Chen, Antonio Garcia-Uceda, Jiahang Su, Gijs van Tulder, Lennard Wolff, Theo van Walsum, Marleen de Bruijne

In this paper, we propose a novel label refinement method to correct such errors from an initial segmentation, implicitly incorporating information about label structure.

Deep learning-based retinal vessel segmentation with cross-modal evaluation

no code implementations MIDL 2019 Luisa Sanchez Brea, Danilo Andrade De Jesus, Stefan Klein, Theo van Walsum

The main goal is to analyse if a model trained in one of two modalities, Fundus Photography (FP) or Scanning Laser Ophthalmoscopy (SLO), is transferable to the other modality accurately.

Dynamic Coronary Roadmapping via Catheter Tip Tracking in X-ray Fluoroscopy with Deep Learning Based Bayesian Filtering

no code implementations11 Jan 2020 Hua Ma, Ihor Smal, Joost Daemen, Theo van Walsum

The proposed roadmapping and tracking approaches were validated on clinical X-ray images, achieving accurate performance on both catheter tip tracking and dynamic coronary roadmapping experiments.
