Description and use of Three-Dimensional Numerical Phantoms of Cardiac Computed Tomography Images
(MDPI, 2022)
The World Health Organization indicates the top cause of death is heart disease. These diseases can be detected using several imaging modalities, especially cardiac computed tomography (CT), whose images have imperfections ...
Compact and extended objects from self-interacting phantom fields
(2016-07-05)
In this work, we investigate localized and extended objects for gravitating, self-interacting phantom fields. The phantom fields come from two scalar fields with a wrong-sign (negative) kinetic energy term in the Lagrangian. ...
REALISTIC IVUS IMAGE GENERATION IN DIFFERENT INTRALUMINAL PRESSURES
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Intravascular ultrasound (IVUS) phantoms are important to calibrate and evaluate many IVUS imaging processing tasks. However, phantom generation is never the primary focus of related works; hence, it cannot be well covered, ...
Reconstruction of segmented human voxel phantoms for skin dosimetry
(Sao Paulo: ABEN, 2009, 2014)
Atherosclerotic plaque characterization using plaque area variation in IVUS images during compression: a computational investigation
(SBEB - Sociedade Brasileira de Engenharia Biomédica, 2014-06-01)
INTRODUCTION: The rupture of atherosclerotic plaques causes millions of death yearly. It is known that the kind of predominant tissue is associated with its dangerousness. In addition, the mechanical properties of plaques ...
Quadrature Slotted Surface Coil Pair for Magnetic Resonance Imaging at 4 Tesla: Phantom Study
(Facultad de Ingeniería, 2012)
Phantom reflexes: Muscle contractions at a frequency not physically present in the input stimuli
(Elsevier, 2007-09)
In the motor system, the periodic stimulation of one Ia-afferent input produces reflex muscle contractions at the input frequency. However, we observed that when two Ia monosynaptic reflex-afferent inputs are involved the ...
