The Possibility for Iodine Concentration Determination in a Phantom with Known Titers of an Iodine-Containing Contrast Agent, by Using Dual-Energy Computed Tomography

open access: yesВестник рентгенологии и радиологии, 2020
Objective: to study the capabilities of single-source dual-energy computed tomography (DECT) in quantifying the concentration of iodine in solutions.Material and methods. Single-source DECT was performed using a phantom containing a set of 5 tubes with a

FPUS23: An Ultrasound Fetus Phantom Dataset With Deep Neural Network Evaluations for Fetus Orientations, Fetal Planes, and Anatomical Features

open access: yesIEEE Access, 2023
Ultrasound imaging is one of the most prominent technologies to evaluate the growth, progression, and overall health of a fetus during its gestation. However, the interpretation of the data obtained from such studies is best left to expert physicians and

Construction and Evaluation of a Multipurpose Performance Check Phantom for Computed Tomography

open access: yesAtom Indonesia, 2020
The use of computed tomography (CT) has become a common practice in medical diagnosis in Indonesia. Its number, however, is not matched by the availability of dedicated-performance-check phantoms. This paper aims to describe the design, construction, and

Pain in traumatic upper limb amputees in Sierra Leone. [PDF]

open access: yes, 2002
Data on 40 upper limb amputees (11 bilateral) with regard to stump pain, phantom sensation and phantom pain is presented. All the patients lost their limbs as a result of violent injuries intended to terrorise the population and were assessed 10-48 ...

On phantom thermodynamics [PDF]

open access: yesPhysics Letters B, 2008
The thermodynamic properties of dark energy fluids described by an equation of state parameter $ω=p/ρ$ are rediscussed in the context of FRW type geometries. Contrarily to previous claims, it is argued here that the phantom regime $ω0$ and $S>0$ in the course of the Universe expansion.

Are we seeing the beginnings of Inflation? [PDF]

open access: yes, 2009
Phantom Cosmology provides an unique opportunity to "connect" the phantom driven (low en- ergy meV scale) dark energy phase to the (high energy GUT scale) inflationary era. This is possible because the energy density increases in phantom cosmology.

Specific absorbed fractions of internal photon and electron emitters in a human voxel-based phantom: A monte carlo study

open access: yesWorld Journal of Nuclear Medicine, 2017
The specific absorbed fraction (SAF) of energy is an essential element of internal dose assessment. Here reported a set of SAFs calculated for selected organs of a human voxel-based phantom.

Analysis of influencing factors of shear wave elastography of the superficial tissue: A phantom study

open access: yesFrontiers in Medicine, 2022
Shear wave elastography (SWE) is widely used in clinical work. But there is no standard protocol and operation specification for SWE acquisition methods, which impacts the diagnosis and clinical staging.

Phantom Rhinitis [PDF]

open access: yesInternational Archives of Allergy and Immunology, 2010
Sensitivity to strong odors has a broad differential diagnosis. A presentation is made of a 60-year-old man with lifelong mild allergic rhinitis and a superimposed 4-year history of sensitivity to smells. He had no response to medical treatments or allergic immunotherapy. His physical examination was unremarkable.

Unifying phantom inflation with late-time acceleration: scalar phantom-non-phantom transition model and generalized holographic dark energy

open access: yes, 2005
The unifying approach to early-time and late-time universe based on phantom cosmology is proposed. We consider gravity-scalar system which contains usual potential and scalar coupling function in front of kinetic term.
