Background Techniques for the evaluation of regionaland global left-ventricular wall motion parameters based on strain analyzes are emerging in cardiac magnetic resonance (CMR) imaging. Some of these techniques, such as tagging, require dedicated CMR sequences at the time of the examination. Other approaches are based on post-processing of routine imaging studies such as feature-tracking. Commo...

effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated.  experiments were carried out in the range of 25-600 ºc and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. time-position trajectory of particles was obtained by radioactive particle tracking technique. these data were used for determination of mean velocities of...

Background Catheter-based ablation techniques are widely applied in the restoration of sinus rhythm. The latter may result in an improvement of left heart function in patients with atrial fibrillation (AF). Cardiovascular magnetic resonance (CMR) feature tracking (FT) might help detect subtle wall-motion abnormalities. We aimed to analyze existence and reversibility of subtle cardiac dysfunctio...

Background Three-dimensional high-resolution PSIR LGE [1], flowindependent vessel wall imaging [2], or T1 mapping [3] are all implemented with interleaved sequences, where the same volume is imaged multiple times with different inherent contrast. These volumes are then processed together to generate additional information, e.g. recovering the sign of magnetization, depicting vessel walls via su...

The PlatoCAVE, the MiniCAVE, and the C2 are immersive stereoscopic projectionbased virtual reality environments oriented toward group interactions. As such they are particularly suited to collaborative efforts in data analysis and visual data mining. In this article, we provide an overview of virtual reality in general, including immersive projection technology, and the use of stereoscopic disp...

BACKGROUND Immunoglobulin amyloid light-chain (AL)-related cardiac amyloidosis (CA) has a worse prognosis than either wild-type (ATTRwt) or mutant (ATTRm) transthyretin (TTR) CA. Detailed echocardiographic studies have been performed in AL amyloidosis but not in TTR amyloidosis and might give insight into this difference. We assessed cardiac structure and function and outcome in a large populat...
