  author={Hao Xu and Steven A. Niederer and Steven E. Williams and David E. Newby and Michelle Claire Williams and Alistair A. Young},
Coronary computed tomography angiography (CCTA) provides detailed anatomical information on all chambers of the heart. Existing segmentation tools can label the gross anatomy, but addition of application-specific labels can require detailed and often manual refinement. We developed a U-Net based framework to i) extrapolate a new label from existing labels, and ii) parcellate one label into multiple labels, both using label-to-label mapping, to create a desired segmentation that could then be… 

Surface Analysis with Vision Transformers

Experiments show that the SiT outperforms many surface CNNs, while indicating some evidence of general transformation invariance, and validate the performance of the proposed Surface Vision Transformer on two brain age prediction tasks in the developing Human Connectome Project (dHCP) dataset.

Surface Vision Transformers: Flexible Attention-Based Modelling of Biomedical Surfaces

Surface Vision Transformers (SiT) demonstrate consistent improvement over geometric deep learning methods for brain age and fluid intelligence prediction and achieve comparable performance on calcium score classification to standard metrics used in clinical practice.



Multi-label Whole Heart Segmentation Using CNNs and Anatomical Label Configurations

Results on the MICCAI 2017 Multi-Modality Whole Heart Segmentation (MM-WHS) challenge show that the proposed architecture performs well on the provided CT and MRI training volumes, delivering in a three-fold cross validation an average Dice Similarity Coefficient over all heart substructures.

Four-Chamber Heart Modeling and Automatic Segmentation for 3-D Cardiac CT Volumes Using Marginal Space Learning and Steerable Features

An automatic four-chamber heart segmentation system for the quantitative functional analysis of the heart from cardiac computed tomography (CT) volumes is proposed and an efficient and robust approach for automatic heart chamber segmentation in 3D CT volumes is developed.

Left Atrial Appendage Segmentation Using Fully Convolutional Neural Networks and Modified Three-Dimensional Conditional Random Fields

A robust method for automatic LAA segmentation on computed tomographic angiography (CTA) data using fully convolutional neural networks with three-dimensional (3–D) conditional random fields (CRFs) is proposed.

Low-attenuation non-calcified plaque on coronary CT angiography predicts myocardial infarction Results from the multicenter SCOT-HEART trial

This post hoc analysis of a multicenter randomized controlled trial of CCTA in patients with stable chest pain investigated the association between the future risk of fatal or nonfatal myocardial infarction and low-attenuation plaque burden, cardiovascular risk score, coronary artery calcium score or obstructive coronary artery stenoses.

2019 ESC Guidelines for the diagnosis and management of chronic coronary syndromes.

The Guidelines presented here refer to the management of patients with CCS, which can be conveniently categorized as either acute coronary syndromes (ACS) or chronic coronary syndrome (CCS).

A High-Resolution Atlas and Statistical Model of the Human Heart From Multislice CT

This paper presents a detailed atlas and spatio-temporal statistical model of the human heart based on a large population of 3D+time multi-slice computed tomography sequences, and the framework for its construction.
