Accelerated MR physics simulations on multi-GPU systems
Xanthis, C. G.; Venetis, I. E.; Aletras, A. H. (2013)A multi-GPU approach of MRISIMUL, a recently developed step-by-step comprehensive MR physics simulator of the Bloch equation, is presented in this study. The specific aim was to apply MRISIMUL on multi-GPU systems so as ... -
Heterogeneity of Intramural Function in Hypertrophic Cardiomyopathy Mechanistic Insights From MRI Late Gadolinium Enhancement and High-Resolution Displacement Encoding With Stimulated Echoes Strain Maps
Aletras, A. H.; Tilak, G. S.; Hsu, L. Y.; Arai, A. E. (2011)Background-In hypertrophic cardiomyopathy (HCM), myocardial abnormalities are commonly heterogeneous. Two patterns of late gadolinium enhancement (LGE) have been reported: a bright "confluent" and an intermediate intensity ... -
High performance MRI simulations of motion on multi-GPU systems
Xanthis, C. G.; Venetis, I. E.; Aletras, A. H. (2014)Background: MRI physics simulators have been developed in the past for optimizing imaging protocols and for training purposes. However, these simulators have only addressed motion within a limited scope. The purpose of ... -
MRISIMUL: A GPU-Based Parallel Approach to MRI Simulations
Xanthis, C. G.; Venetis, I. E.; Chalkias, A. V.; Aletras, A. H. (2014)A new step-by-step comprehensive MR physics simulator (MRISIMUL) of the Bloch equations is presented. The aim was to develop a magnetic resonance imaging (MRI) simulator that makes no assumptions with respect to the ... -
Navigated DENSE strain imaging for post-radiofrequency ablation lesion assessment in the swine left atria
Schmidt, E. J.; Fung, M. M.; Ciris, P. A.; Song, T.; Shankaranarayanan, A.; Holmvang, G.; Gupta, S. N.; Chaput, M.; Levine, R. A.; Ruskin, J.; Reddy, V. Y.; D'Avila, A.; Aletras, A. H.; Danik, S. B. (2014)Aims Prior work has demonstrated that magnetic resonance imaging (MRI) strain can separate necrotic/stunned myocardium from healthy myocardium in the left ventricle (LV). We surmised that high-resolution MRI strain, using ... -
A new validated T2* analysis method with certainty estimates for cardiac and liver iron load determination
Bidhult, S. L.; Xanthis, C. G.; Liljekvist, L. L.; Greil, G. F.; Nagel, E.; Aletras, A. H.; Heiberg, E.; Hedström, E. (2015) -
Simulating MR imaging for the human embryonic heart
