Motion correction and myocardial perfusion SPECT using manufacturer provided software. Does it affect image interpretation?
Purpose Myocardial perfusion SPECT is an excellent tool for the assessment of coronary artery disease (CAD); however, it is affected by several artifacts, such as patient motion during acquisition, which increases ...

Maximum likelihood estimation of cardiac fiber bundle orientation from arbitrarily spaced diffusion weighted images
We propose an estimation scheme for local fiber bundle direction in the left ventricle directly from gray values of arbitrarily spaced cardiac diffusion weighted images (DWI). The approach is based on a parametric and ...
Simultaneous Motion Detection and Background Reconstruction with a Conditional Mixed-State Markov Random Field
In this work we present a new way of simultaneously solving the problems of motion detection and background image reconstruction. An accurate estimation of the background is only possible if we locate the moving objects. ...
Non-Markovian expansion in quantum Brownian motion
We consider the non-Markovian Langevin evolution of a dissipative dynamical system in quantum mechanics in the path integral formalism. After discussing the role of the frequency cutoff for the interaction of the system ...
Eletrogoniometria de punho : avaliação de sensores e procedimentos matemáticos de correção para reduzir erros de medida
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Fisioterapia, 2013-02-21)
The human movement record is an essential requirement for biomechanical, clinical and occupational analysis, allowing assessments of postural variation, occupational risks and improvement of preventive programs in physical ...
3D whole-heart isotropic sub-millimeter resolution coronary magnetic resonance angiography with non-rigid motion-compensated PROST.
Abstract Background To enable free-breathing whole-heart sub-millimeter resolution coronary magnetic resonance angiography (CMRA) in a clinically feasible scan time by combining low-rank patch-based undersampled reconstruction ...
