Cardiac MR Image Segmentation Techniques: an overview [PDF]
arXiv, 2015 Broadly speaking, the objective in cardiac image segmentation is to delineate the outer and inner walls of the heart to segment out either the entire or parts of the organ boundaries. This paper will focus on MR images as they are the most widely used in cardiac segmentation -- as a result of the accurate morphological information and better soft ...

Remarks on the morphology of the papillary muscles of the right ventricle [PDF]
, 2005 In addition to the papillary muscles of right ventricle referred to in anatomical nomenclature, namely the anterior, posterior and septal, we have distinguished the “conal papillary muscle” and the “papillary muscle of the posterior ...

Advanced Science, EarlyView.During a heart attack, neutrophils rapidly activate and differentiate into a specific subset characterized by high levels of MMP9, a tissue‐damaging enzyme, via the SPI1/CST7 pathway. These neutrophils form harmful net‐like structures (Neutrophil extracellular traps, NETs) that exacerbate heart injury.

Segmentation of Right Ventricle in 3D Ultrasound Recordings [PDF]
, 2008 This thesis presents segmentation of the right ventricle of the heart in real-time tracking of 3D ultrasound recordings. A simple deformable model for the right ventricle is developed based on statistical data from manual segmentations, and the model ...

Metal–Organic Frameworks: Unlocking New Frontiers in Cardiovascular Diagnosis and Therapy
Advanced Science, EarlyView.Metal–organic frameworks (MOFs), are composed of metal ions and bridging organic ligands, are recognized as an excellent platform for host‐gust chemistry. Its rich structural composition, modifiable sites, and multilevel pore distribution can provide delivery and release of signaling molecules, probes, and therapeutic drugs, which exhibit great medical

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]
arXiv, 2015 This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria. One of the specificities of our approach is to model the atria as a surface, which is the kind of data typically provided
