CardioDrift: Automatic Cardiac Motion Tracking on a 3D Atlas Mesh via Shape-aware Coherent Point Drift with Slice Shift Correction

Read the original on arXiv Computer Vision →

CardioDrift is a fully automatic, atlas‑based framework that tracks cardiac motion on a 3D atlas mesh using a shape‑aware Coherent Point Drift algorithm. It jointly registers atlas surfaces of multiple cardiac regions to cine CMR segmentation contours across the cardiac cycle, while embedding slice‑shift correction to reduce misalignment artefacts. In evaluations on 1,301 UK Biobank subjects and the M&M dataset, CardioDrift achieved Dice similarity coefficients of 92.23 ± 8.70 % for the left ventricle, 82.11 ± 7.56 % for the myocardium, and 88.69 ± 4.13 % for the right ventricle, outperforming all baselines on every distance and overlap metric.

A latent ODE approach to full-cycle biventricular cardiac motion modeling from cine MRI

The paper introduces a latent dynamical model that captures full‑cycle biventricular cardiac motion from cine MRI using a heart‑rate‑aware neural ODE and a graph‑based mesh autoencoder. It encodes ventricular anatomy and motion as a continuous latent trajectory, with a covariate‑conditioned prior for the end‑diastolic state and a Cox model linking deviations to incident heart failure. In a large UK Biobank cohort, adding the latent score to existing risk equations improved predictive performance, outperforming several established cardiac markers and alternative modeling approaches.

A Latent ODE Approach to Spatiotemporal Modeling of Cine Cardiac MRI

arXiv:2606. 26718v1 Announce Type: new Abstract: Cardiac magnetic resonance imaging (CMR) captures rich spatiotemporal information about ventricular structure and motion, but conventional risk models use only a few image-derived indices from selected cardiac phases.

Transformer-Guided Graph Attention for Direct Cardiac Mesh Reconstruction: A Structural Digital Twin Framework

arXiv:2606. 13188v1 Announce Type: cross Abstract: Building patient-specific cardiac models sits at the heart of precision cardiology, yet getting those models into clinical use keeps running into the same wall: mesh generation is slow, messy, and frustrating.

Orientation-Robust Latent Motion Trajectory Learning for Annotation-free Cardiac Phase Detection in Fetal Echocardiography

The paper introduces ORBIT, a self‑supervised method for detecting end‑diastolic and end‑systolic cardiac phases in fetal echocardiography without manual annotations. ORBIT learns a latent motion trajectory through registration, enabling orientation‑robust identification of phase transitions across diverse fetal heart positions. Evaluated on normal and congenital heart disease cases, it achieves low mean absolute errors (≈1.9–2.4 frames) and outperforms prior annotation‑free approaches that assume fixed orientations.
