Magnetic field is the spaces in which kinetic and electrically charged particles are under influence of power and is formed following that electrons revolve around the nucleus and themselves. Magnetic field is a phenomenon which cannot be directly seen or easily felt, however its results can be seen and felt. Today, with the development of technology its measurement via devices has become possible. All substances are of magnetic fields, either living or non-living, weak or strong. Like every substance

A single gamma-ray computed tomography (CT) technique, which is a part of unique dual-source gamma-ray computed tomography (DSCT) scanner, was used in this study. This DSCT was originally developed in-house and designed by Varma [49] and the team of Oak Ridge National Laboratory (ORNL) to allow researchers to image and quantify the internal distributions of two- or three-phase flow, which is encountered in different multiphase reactors or flow systems at different operating conditions in a noninvasive

PHYSICAL PRINCIPLES An x ray is similar to light and has both particle and wave nature. That basic working of a x ray CT scan is the photons of x ray radiation comes in contact with the electron clouds in atoms. This can happen either by photo electric effect or by scattering. COMPTON SCATTERING The first type of interaction of x rays in CT energy range is scattering and one of it is Compton scattering. In Compton scattering photons interact with the outer shell electrons of the atom an ejects it

utilization of “X-ray Imaging”. To test this, we observed the change in utilization if a seventh X-ray machine is bought.2 Adding a seventh X-ray machine does decrease utilization of the “X-ray Imaging” activity, suggesting that machines and technical assistants will have more down-time, on average, if there are 7 machines vs 6 machines. Since the relationship between utilization and wait times is exponential when a system has variability, a 12% reduction in utilization at X-ray imaging should have

professional with the visualisation of the internal structure of human body. This visualisation is of great significants to the medical professionals in diagnostics and the treatment of diseases. Imaging is obtained by using a source such as X-ray, ultrasound, gamma ray photons and magnetic fields. Since these sources obtain radiations that can be harmful for the body, it is important that the doses are being reduced. Each individual imaging technique provides the professionals with specific set of information

diseases. For instance, the images can reveal the limits of a tumour of a cancer patient, allowing more precise surgery and radiation therapy. There are no known biological hazards of MRI because it uses radiation in the radiofrequency range unlike x ray and computed tomography. The radio waves being used are similar to waves used for radios and cell phones which are found all around us. Due to its long wavelengths, it does not damage tissue as it passes through. The use of harmless radiation provide

may be detected during a lumbar or abdominal x-ray done for other reasons such as abdominal or back pain. Prior to the 1970s, an abdominal or lumbar x-ray was the way to monitor the growth of an aneurysm, although the purpose of a radiograph is to show aortic calcifications (Ware-McGee & Marinelli, 2013). On the x-ray, an aneurysm may be present as a curved calcification along the vertebral column. Figure 2 illustrates an AP and lateral abdomen x-ray of an AAA with calcification of the aortic wall

Introduction Today, in the United States back pain affects more than 80% of people in the U.S. at a cost of more than $100 billion a year. Back pain can lead to many emotions from those suffering, chronic pain leads to anger, immobility, depression, and other crippling effects. While the causes from back pain range from far and between, the purpose of this research paper will tell the story of Spinal Stenosis and its effect on many Americans today. Through this paper, the reader will learn Spinal
