Abstract:

Interpretation of radiolucent foreign bodies (FBs) is a common task charged to pediatric radiologists. The use of a motion compensated technique to decrease breathing motion on images would greatly decrease overall exposure to ionizing radiation and increase access to treatment yielding a great impact on clinical care. This study reports on the methodology and materials used to construct an in-house anthropomorphic phantom for investigating image quality in digital tomosynthesis protocols for volumetric imaging of the pediatric airway.

Off and on for fifteen years I traveled the country to research the life and work of the nineteenth-century physician S. Weir Mitchell.

His groundbreaking work with rattlesnake venom earned him an international reputation, and his work with gunshot wounds, burning pain, and phantom limbs during the U.S. Civil War won him the title of the “Father of American Neurology.” Mitchell also possessed an impressive faci

Abstract:

Results of calculating the sonic boom generated in a supersonic air flow by two bodies (disk and slender body of revolution) are presented. The bodies are arranged one behind the other. The slender body is aerodynamically shaded by the disk. The free-stream Mach number is 2. The calculations are performed by a combined method of “phantom bodies.” By changing the disk position and its size, it is possible to reduce the sonic boom level. Based on the calculation results, the gas-dynamic factors affecting the sonic boom level are described.

Calculations are performed for a sonic boom generated by two bodies (a disk and a thin body of revolution) in the case of local heating of the incident air flow. The bodies are in a heat trail behind the heating region. The thin body is in an aerodynamic shadow behind the disk. The Mach number of the cold air flow is 2. The calculations are carried out using the combined method of "phantom bodies".

Theories of grief based on Freud's “Mourning and Melancholia” typically portray mourning as a disembodied process.

This article brings together two concepts, ‘phantom fat’ and ‘liminal fat’, which both aim to grasp how fat in contemporary culture becomes a kind of material immateriality, corporeality in suspension. Comparing the spheres of representation and experience, we examine the challenges and usefulness of these concepts, and feminist fat studies perspectives more broadly, to feminist scholarship on the body. We ask what connects and disconnects fat corporeality and fat studies from ways of theorising other embodied differences, like gender, ‘race’, disability, class and sexuality, especially when t

Abstract:

The level of the sonic boom arising due to local heating of the air flow ahead of a slender body flying at a supersonic velocity in the thermal wake behind the heating regions is calculated. The Mach number of the cold air flow is 2. The calculations are performed by a combined method of “phantom bodies.” It is demonstrated that consecutive local heating of the incident flow in two regions ahead of the body ensures reduction of the sonic boom level by more than 30% as compared to the sonic boom generated by the body in the cold flow.

Abstract:

The problem of a sonic boom generated by a slender body and local regions of supersonic flow heating is solved numerically. The free-stream Mach number of the air flow is 2. The calculations are performed by a combined method of phantom bodies. The results show that local heating of the incoming flow can ensure sonic boom mitigation. The sonic boom level depends on the number of local regions of incoming flow heating. One region of flow heating can reduce the sonic boom by 20% as compared to the sonic boom level in the cold flow. Moreover, consecutive heating of the incoming flow in two region

Therefore, the aim of this study was to produce homemade simulations of radiolucent foreign bodies for veterinary student demonstrations that could be identified sonographically

In addition, 3D phantoms are used to diagnose the gravity of accidental exposure to radiation. In such cases, there may be from 10 to more than 1000 subjects to be diagnosed simultaneously.

Abstract:

Background: Electrical stimulation is increasingly relevant in a variety of medical treatments. In this study, surface electrical stimulation was evaluated as a method to non-invasively target a neural function, specifically natural sensation in the distal limbs. Method: Electrodes were placed over the median and ulnar nerves at the elbow and the common peroneal and lateral sural cutaneous nerves at the knee. Strength-duration curves for sensation were compared between nerves. The location, modality, and intensity of each sensation were also analyzed. In an effort to evoke natural sensations,

Abstract:

With advancements in aesthetic medicine, breast augmentation has become a popular plastic surgery worldwide, typically performed using either fine-needle injection or silicone implants. Both carry complication risks from rupture over time. In this study, we aimed to reduce misjudgments and increase diagnostic value by developing an MRI technique that can produce water- and silicone-specific images from MRI scans of phantoms (Natrelle® saline-filled breast implants) and human bodies. Pig oil, soybean oil, and normal saline were used to simulate human breast tissue, and two common types of breas

Abstract When comparing the performance of different industrial X-ray computed tomography (CT) systems, reconstruction algorithms, or scan protocols, it is important to assess how well the required inspection and measurement tasks can be performed. Furthermore, it can be very informative to quantify image quality (IQ) metrics that can provide insight into the IQ characteristics that lead to the resulting inspection or measurement task performance. Inspection and measurement task performance is determined by basic characteristics such as spatial resolution; feature contrast, size, and shape; ra

Introduction The quantification of heating effects during exposure to ultrasound is usually based on laboratory experiments in water and is assessed using extrapolated parameters such as the thermal index. In our study, we have measured the temperature increase directly in a simulator of the maternal–fetal environment, the ‘ISUOG Phantom’, using clinically relevant ultrasound scanners, transducers and exposure conditions.

Abstract We have been developing a medical imaging system using a Compton camera and demonstrated the imaging ability of Compton camera for 99mTc-DMSA accumulated in rat kidneys. In this study, we performed imaging experiments using a human body phantom to confirm its applicability to human imaging. Preliminary simulations were conducted using a digital phantom with varying activity ratios between the kidney and body trunk regions. Gamma rays (141 keV) were generated and detected by a Compton camera based on a silicon and cadmium telluride (Si/CdTe) detector. Compton images were reconstructed

Abstract:

When students learn radiographic positioning during radiography practical training in educational institutions, they adjust the angle of the body using positioning aids and angle gauges. In contrast, radiologic technologists position patients using their own hands in clinical environments. In recent years, virtual simulations have been used to help students improve their clinical skills. However, because the existing simulations use computer-generated virtual environments, students cannot actually position human bodies or anthropomorphic phantoms. Therefore, we developed a simulation using aug

This essay takes its point of departure from a well known excerpt found in the final pages of Michel Foucault’s text, The History of Sexuality: Volume One. It reads as follows: It is the agency of sex that we must break away from, if we aim-through a tactical reversal of the various mechanisms of sexuality- to counter the grips of power with the claims of bodies, pleasures and knowledges, in their multiplicity and their possibility of resistance. The rallying point for the counterattack against the deployment of sexuality ought not to be sex-desire, but bodies and pleasures. (157) Here for the

   The doppelgänger (literally ‘double-goer’) of 18th and 19th century European literature and lore is a sinister likeness that dogs and shadows a protagonist heralding their death or descent into madness – a ‘spectral presentiment of disaster’ (Schwartz 84). Recently the term ‘digital doppelgänger’ has been adopted by the English-speaking entertainment and technology press to refer to a digital image of an actor or performer; whether that image is a computer-generated wire-frame model, an amalgamation of old film footage and artistry, or a three dimensional laser scan of the
