Journal of Neurology Neurosurgery & Psychiatry, 2018 A major goal of neuroprosthetics is to design artificial limbs that are experienced (‘embodied’) like real limbs. However, despite important technological advances, this goal has not been reached and prosthesis embodiment is still very limited ...

Medical Physics (Lancaster), 2018 PURPOSE Imaging phantoms are widely used for testing and optimization of imaging devices without the need to expose humans to irradiation. However, commercially available phantoms are commonly manufactured in simple, generic forms and sizes and therefore

The ADAM-pelvis phantom—an anthropomorphic, deformable and multimodal phantom for MRgRT
Physics in Medicine and Biology, 2019 Applicability and accuracy of the rapidly developing tools and workflows for image-guided radiotherapy need to be validated under realistic treatment-like conditions.

4D XCAT phantom for multimodality imaging research.
Medical Physics (Lancaster), 2010 PURPOSE The authors develop the 4D extended cardiac-torso (XCAT) phantom for multimodality imaging research. METHODS Highly detailed whole-body anatomies for the adult male and female were defined in the XCAT using nonuniform rational B-spline (NURBS ...

Soft 3D-Printed Phantom of the Human Kidney with Collecting System
Annals of Biomedical Engineering, 2016 Organ models are used for planning and simulation of operations, developing new surgical instruments, and training purposes. There is a substantial demand for in vitro organ phantoms, especially in urological surgery. Animal models and existing simulator

Journal of Cardiovascular Magnetic Resonance, 2016 BackgroundT1 mapping and extracellular volume (ECV) have the potential to guide patient care and serve as surrogate end-points in clinical trials, but measurements differ between cardiovascular magnetic resonance (CMR) scanners and pulse sequences.

A phantom road experiment reveals traffic noise is an invisible source of habitat degradation
Proceedings of the National Academy of Sciences of the United States of America, 2015 Significance Using landscape-scale traffic noise playbacks to create a “phantom road,” we find that noise, apart from other factors present near roads, degrades the value of habitat for migrating songbirds.

Mod.Phys.Lett. A21 (2006) 1099-1106, 2005 The Observed Perlmutter-Riess Acceleration (OPRA) implies that the expansion of the Universe is currently increasing and is motivation for the so-called phantom energy models. We consider the dynamics of phantom scalar field models. An important physical time constraint, which can be used to rule out many cosmological models, is obtained from the ...

Phantom Dark Energy and its Cosmological Consequences [PDF]
, 2007 I discuss the dark energy characterized by the violation of the null energy condition ($\varrho + p \geq 0$), dubbed phantom. Amazingly, it is admitted by the current astronomical data from supernovae. We discuss both classical and quantum cosmological models with phantom as a source of matter and present the phenomenon called phantom duality.
