Object detection has witnessed significant progress by relying on large, manually annotated datasets.
Few-shot semantic segmentation (FSS) has great potential for medical imaging applications.
Cardiac MR image segmentation is essential for the morphological and functional analysis of the heart.
In this work, we propose a deep learning approach for parallel magnetic resonance imaging (MRI) reconstruction, termed a variable splitting network (VS-Net), for an efficient, high-quality reconstruction of undersampled multi-coil MR data.
Deep unsupervised domain adaptation (UDA) aims to improve the performance of a deep neural network model on a target domain, using solely unlabelled target domain data and labelled source domain data.

At the highest level of this hierarchy, a two-dimensional latent space is simultaneously optimised to discriminate distinct clinical conditions, enabling the direct visualisation of the classification space.
Accurate segmentation of heart structures imaged by cardiac MR is key for the quantitative analysis of pathology.
We look into robustness of deep learning based MRI reconstruction when tested on unseen contrasts and organs.

Motion analysis is used in computer vision to understand the behaviour of moving objects in sequences of images.
The proposed pipeline is fully automated, due to network's ability to infer landmarks, which are then used downstream in the pipeline to initialise atlas propagation.

However, current approaches to the diagnosis of cardiovascular diseases often rely on subjective human assessment as well as manual analysis of medical images.
