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.

Prior-knowledge-informed deep learning for lacune detection and quantification using multi-site brain MRI

no code implementations18 Jun 2023 Bo Li, Jeroen de Bresser, Wiro Niessen, Matthias Van Osch, Wiesje M. van der Flier, Geert Jan Biessels, Meike W. Vernooij, Esther Bron

Lacunes of presumed vascular origin, also referred to as lacunar infarcts, are important to assess cerebral small vessel disease and cognitive diseases such as dementia.

A hybrid deep learning framework for integrated segmentation and registration: evaluation on longitudinal white matter tract changes

no code implementations26 Aug 2019 Bo Li, Wiro Niessen, Stefan Klein, Marius de Groot, Arfan Ikram, Meike Vernooij, Esther Bron

Registration between time-points is used either as a prior for segmentation in a subsequent time point or to perform segmentation in a common space.

Segmentation

Reproducible White Matter Tract Segmentation Using 3D U-Net on a Large-scale DTI Dataset

no code implementations26 Aug 2019 Bo Li, Marius de Groot, Meike Vernooij, Arfan Ikram, Wiro Niessen, Esther Bron

As a consequence, there is a large interest in the automatic segmentation of white matter tract in diffusion tensor MRI data.

Weakly Supervised Object Detection with 2D and 3D Regression Neural Networks

no code implementations5 Jun 2019 Florian Dubost, Hieab Adams, Pinar Yilmaz, Gerda Bortsova, Gijs van Tulder, M. Arfan Ikram, Wiro Niessen, Meike Vernooij, Marleen de Bruijne

For comparison, we modify state-of-the-art methods to compute attention maps for weakly supervised object detection, by using a global regression objective instead of the more conventional classification objective.

Hydranet: Data Augmentation for Regression Neural Networks

no code implementations12 Jul 2018 Florian Dubost, Gerda Bortsova, Hieab Adams, M. Arfan Ikram, Wiro Niessen, Meike Vernooij, Marleen de Bruijne

The proposed method reached an intraclass correlation coefficient between ground truth and network predictions of 0. 73 on the first task and 0. 84 on the second task, only using between 25 and 30 scans with a single global label per scan for training.

GP-Unet: Lesion Detection from Weak Labels with a 3D Regression Network

no code implementations22 May 2017 Florian Dubost, Gerda Bortsova, Hieab Adams, Arfan Ikram, Wiro Niessen, Meike Vernooij, Marleen de Bruijne

We train a regression network with a fully convolutional architecture combined with a global pooling layer to aggregate the 3D output into a scalar indicating the lesion count.

A Discriminative Event Based Model for Alzheimer's Disease Progression Modeling

1 code implementation21 Feb 2017 Vikram Venkatraghavan, Esther Bron, Wiro Niessen, Stefan Klein

To evaluate the accuracy, we performed extensive experiments on synthetic data simulating the progression of Alzheimer's disease.
