We present preliminary evidence that left ventricular twist can be observed and thus estimated from rotational coronary angiography. Our method is based on an ellipsoidal parametric model initially developed for functional analysis of cardiac tagged MRI. First, we fit the model to 3D coronary artery centerlines reconstructed from rotational angiography and then use 3D/2D registration to optimize for the functional parameters driving the model. On two clinical acquisitions, we show that our… 
Detecting Anatomical Landmarks for Motion Estimation in Weight-Bearing Imaging of Knees
TLDR
A method to automatically detect anatomical landmarks in projection domain X-ray images irrespective of the viewing direction is devised and results are promising and encourage further investigations on the use of anatomical landmarks for motion management.
Machine Learning for Medical Image Reconstruction
TLDR
It is demonstrated how superresolution (SR) can be utilized to maintain adequate SNR for accurate quantification of the T2 relaxation time biomarker, while simultaneously generating high-resolution images.

Parametric LV Model Fitting to Coronary Arteries
TLDR
Results are promising and form the basis to extend the parametric left ventricular heart model originally developed for tagged MRI to the centerlines of coronary arteries reconstructed from rotational coronary angiography to 3D+t in order to monitor radial and longitudinal contraction.
Torsional Heart Motion in Cone-beam Computed Tomography Reconstruction
TLDR
The results indicated that limited angle problems may occur for large twist angles in interventional settings, leading to degraded image quality, however, degradations were subtle and should not affect most practical cases.

TLDR
By plotting the variations over time of the extracted LV model parameters from normal and abnormal heart data along the long axis, the authors are able to quantitatively characterize their differences.

Three-dimensional modeling for functional analysis of cardiac images, a review
TLDR
3-D model-based approaches have the capability to improve the diagnostic value of cardiac images, but issues as robustness, 3-D interaction, computational complexity and clinical validation still require significant attention.
Symmetry, outliers, and geodesics in coronary artery centerline reconstruction from rotational angiography
TLDR
Generic extensions to symbolic centerline reconstruction algorithms that target symmetrization, outlier rejection, and topology recovery on asymmetrically reconstructed point clouds yield superior reconstruction quality in all cases and effectively removed erroneously reconstructed points.

TLDR
Methods of image synthesis and dynamic animation for visualizing the estimated results of the time-varying left ventricle shape, motion, and deformations are described, showing the success of the authors' hierarchical decomposition based approach.
