Computed Tomography (CT) and Magnetic Resonance (MR) imaging techniques have become an important role in diagnosing the vascular diseases. Before a clinical trial of the newly developed techniques, it is essential to evaluate them on a phantom. However, there is no existing arterial A Dynamic Arterial Tree Phantom for studies 89 tree phantom that serves for flood flows. To that end, we design a...

Phantom limb pain affects an alarming amount of amputees. Little is known about the true cause of phantom limb pain, making it difficult to establish a standard treatment for it. This literature review looks at the etiology of phantom limb pain as well as the three major forms of treatment for phantom limb pain: pharmacological, invasive, and supportive. These three forms of treatment use diffe...

The present study quantified surface doses on several rectangular phantom setups and on curved surface phantoms for a 6 MV photon field using the Attix parallel-plate chamber and Gafchromic EBT2 film. For the rectangular phantom setups, the surface doses on a homogenous water equivalent phantom and a water equivalent phantom with 60 mm thick lung equivalent material were measured. The measureme...

PURPOSE The emergence of thermal modalities has promoted the use of heat-sensitive phantoms for calibration, measurement, and verification purposes. However, development of durable phantoms with high precision ability to represent the temperature distribution remains a challenge. This study aims to introduce a reusable phantom that provides an accurate assessment of the heated region in various...

A phantom limb is the sensation that an amputated limb is still attached to the body and is moving together with other body parts. Phantom limb phenomenon is often described on the basis of the patient's subjective sense, for example as represented using a visual analog scale (VAS). The aim of this study was to propose a novel quantification method for behavioral aspect of phantom limb by psych...

We have investigated a simplification procedure of the Specific Absorption Rate (SAR) compliance test for mobile phones. In this paper, it is shown that maximum averaged SARs of a flat phantom and the SAM phantom are measured and compared for 38 mobile phones in the market in order to investigate on the applicability of using the flat phantom instead of the SAM phantom for the SAR measurement. ...

PURPOSE Develop a technique to fabricate a 3D anthropomorphic breast phantom with known ground truth for image quality assessment of 2D and 3D breast x-ray imaging systems. METHODS The phantom design is based on an existing computer model that can generate breast voxel phantoms of varying composition, size, and shape. The physical phantom is produced in two steps. First, the portion of the vo...

This chapter is supported by Grant MT-12052 and a research scholarship from the Medical Research Council of Canada. After an amputation many patients awake from the anesthesia feeling certain that the operation has not been performed. They feel the lost limb so vividly that only when they reach out to touch it, or peer under the bed sheets to see it, do they realize it has been cut off. This ph...
