Ultrasound Essay

image that can be analyzed to determine or rule out a diagnosis. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. A diagnostic medical sonographer works directly with patients in a dimly lit room with imaging machines. The sonographer gets the medical history of the patient and prepares the patient for an ultrasound examination. The sonographer explains the noninvasive procedure and

Tomography(CT), Magnetic Resonance Imagine (MRI) and Ultrasound (US), modalities used disease and pathology diagnosis. It will look at the scientific principles. Comparing the risks and hazards associated with each modality when examining pregnant patients. Risk reduction and safety will be discussed. Scientific Principles Computed Tomography CT is cross-sectional image acquisition using the x-ray beam transmission measurements. Unlike MRI and Ultrasound, CT produces ionizing

Mathers, a vascular specialist. Provides information of how a diagnostic ultrasound can be used to detect different aliments that evolves around the human organs, veins and arteries. The job of an Sonographer can examine the patient’s body so that the doctor knows what to do based off the personnel’s finding. For example an ultrasound can detect a blood clot in a person’s leg. However, in order to diagnosis a patient with a ultrasound machine you have to get some training either from a medical school

often affect the pediatric age group. LMs can be macrocystic, microcystic or a combination of the two, and frequently involve the head and neck regions. Ultrasound is useful in the prenatal detection of LMs; however, these lesions can be missed. This case study outlines the incidental finding of a sublingual cyst during a third trimester ultrasound. Postnatal magnetic resonance imaging (MRI) demonstrated a lesion with peripheral enhancement on the anterior and inferior aspect of the tongue, consistent

control is thus the management of these infections to prevent injury to the patient resulting in disease. In the diagnostic ultrasound department, the good use of infection control is critical to avoiding contamination from patient to patient and to the sonographer because of the close proximity to each other and repeated use of medical equipment. Due to the wide use of ultrasound for diagnosis, the sonographer is exposed to a wider variety of potential infection

infanticide to be sure they could have a boy. Now parents who wanted a son, but balked at killing baby daughters were able to choose abortion instead. Even today, there are no proven practices that allow gender detection during the first trimester, and ultrasound is fairly unreliable until approximately the 20th week of pregnancy. Consequently, sex selection often requires late term abortion of a fetus. This practice not only affects the family but the society as a whole. It has caused an increase in the

influences such as temperature and strain. He [2] dealt with the issue of measuring the speed of ultrasound in the material so that at the same time are measured the speed of ultrasound and thickness of the material in several different tubes. For this purpose, he conducted an analysis of time and frequency domain received signal. He listed all theoretical influences on the accuracy of speed of ultrasound, but not experimentally determined or estimated deviation of the actual values. Ali [3] carried

they do. They mainly do ultrasounds on babies, to see the growth and health of the baby. They also do ultrasounds on all different people, if they’re in pain and they need to determine the problem. Their job might seem easy; sometimes it is, but the other times when we discover something wrong with the patient you have to keep it in. You are not allowed to tell them what you just found out; only the doctor can do so. It’s very heartbreaking for them to do baby ultrasounds because sometimes, for some

Science Nile University Giza/ Egypt m.abdelwahab@nu.edu.eg Abstract This paper introduces UltraHaptics, a new technology designed to provide multi-point mid-air haptic feedback above an interactive surface. The technology depends on focusing ultrasound to project separated points of haptic feedback through the display and then directly to the user’s bare hands. This new technology is simple and accessible, which make it easy to enter different fields of industry and have wide applications. Index

Medical Sonography or Ultrasound has advanced rapidly over the years and has a growing popularity. Ultrasound imaging can be seen in 2D, 3D and also 4D. Ultrasound is making it easier to diagnose conditions or simply see a picture of a fetus in a womb. Ultrasound uses high-frequency sound waves to see images inside the body. Sonographers use ultrasound to see everything from a fetus to blood vessels. A sonographer is someone who is trained to perform these examinations. Ultrasound is a very safe way
