Active Sampling for MRI-based Sequential Decision Making

Yuning Du, Jingshuai Liu, Rohan Dharmakumar +1

Despite the superior diagnostic capability of Magnetic Resonance Imaging (MRI), its use as a Point-of-Care (PoC) device remains limited by high cost and complexity. To enable such…

Factorised spatial representation learning: application in semi-supervised myocardial segmentation

Agisilaos Chartsias, Thomas Joyce, Giorgos Papanastasiou +5

The success and generalisation of deep learning algorithms heavily depend on learning good feature representations. In medical imaging this entails representing anatomical informat…

Temporal Uncertainty Localization to Enable Human-in-the-loop Analysis of Dynamic Contrast-enhanced Cardiac MRI Datasets

Dilek M. Yalcinkaya, Khalid Youssef, Bobak Heydari +4

Dynamic contrast-enhanced (DCE) cardiac magnetic resonance imaging (CMRI) is a widely used modality for diagnosing myocardial blood flow (perfusion) abnormalities. During a typical…

Unveiling Fairness Biases in Deep Learning-Based Brain MRI Reconstruction

Yuning Du, Yuyang Xue, Rohan Dharmakumar +1

Deep learning (DL) reconstruction particularly of MRI has led to improvements in image fidelity and reduction of acquisition time. In neuroimaging, DL methods can reconstruct high-…

Disentangled Representation Learning in Cardiac Image Analysis

Agisilaos Chartsias, Thomas Joyce, Giorgos Papanastasiou +4

Typically, a medical image offers spatial information on the anatomy (and pathology) modulated by imaging specific characteristics. Many imaging modalities including Magnetic Reson…
