Introduction
Ultrasound is acoustic energy with a frequency at about 20kHz which is above the capability of human hearing. It is more commonly used in the medical field than food industry. In the medical field, the most significant usage of ultrasound is in sonographic scanners. As these scanners work at 2-18MHz, it produces smaller wavelength which is able to make sonogram of smaller details. As such, ultrasound sound based imaging technique is used to visualize body structures and tissues (Carovac, Smajlovic, & Junuzovic, 2011). Ultrasound contributes to the food industry via its acoustic cavitation in food and dairy processing. For example, extraction using ultrasound technology has shown to increase yield of high value food ingredients while emulsification produces food emulsions with smaller droplet size (Chandrapala, Oliver, Kentish, & Ashokkumar, 2012). In the dairy industry, ultrasound was proved to enhance heat stability of dairy proteins and is used to separate fat from milk (Grieser, 2015). Although most of the reported benefits of using ultrasound in food industry was done in the laboratory, major advances have been made in recent years to utilize ultrasound in commercial processes (Patist & Bates, 2008).
Mechanism?
The intrinsic mechanism of crystallization under the influenced of ultrasonic irradiation was not well understood though there are many researchers working on this topic for the past few years. In spite of that, the two recognized mechanism that
The primary focus of a Diagnostic Medical Sonographer is to create images by using a high-tech instrument which will take images from inside the human body that will be used by doctors to make a medical diagnosis (Society of Diagnostic Medical Sonography, 2015).
An ultrasound is also referred to as a sonogram. It uses a high frequency sound waves to create images of the inside of the body.
Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves to construct an image of internal organs or body structures. The employment rate is is expected to grow 26 percent from 2014 to 2024. Since ultrasound is non-invasive, it is more encouraged than other methods so the career is always in demand. Diagnostic medical sonographers duties are to prepare and maintain diagnostic imaging equipment, taking a patients medical history, answering questions about the procedure, operating the equipment, review images and test results, know the difference between normal and abnormal images, analyze diagnostic information, record findings, and keep track of patient records. Hospitals, offices of physicians, medical
Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies
Diagnostic medical sonographers who are also known as ultrasound technologists, play a very pivotal role in the health industry. Sonographers use specialized 3D imaging machines to generate images of internal body organs and structures which works hand-in-hand with doctors in gathering the necessary data needed for a diagnosis (Reece & Hobbins, 2007). Diagnostic medical sonography has many different branches you may pursue such as obstetrics/gynecology, breast sonography, cardiovascular sonography, and abdominal sonography to name a few (Brent, Jensh, & Beckman, 1991). The limits of authority and legislated scope of practice for sonographers has recently been revised in May 2013 by sixteen representatives from multiple sonography organizations throughout the country (2016). A diagnostic medical sonographer must be a qualified individual who is academically credited as well as clinically skilled before they begin to practice. Affirmation, demonstration, continuing education as well as re-certification from a nationally accredited organization is required for every sonographer (2016).

To achieve my goal to attend Johnston Community College’s Medical Sonography program I have to start by completing an application for general college admission. After completing the admission process I will then have to start on my classes that are required for me to be accepted into the program. Once I fit the requirements for the program I will then I will then I will sign up for the Medical Sonography program, which should take about two years. To successfully reach my goal I may have to cut back on the hours that I take at my part time jobs. At the moment I have a lot of free time which allows me to have two job, once I begin working on my goal I expect to be forced to either quit one of my jobs or to cut back on my hours.
Heart beating fast, adrenaline flowing, and pressure in the air, is what one would expect in a career in a medical field; extremely demanding yet very rewarding and fulfilling. When working in a health care profession, patients often place their trust in a health care stranger’s hands to determine their diagnosis and to establish a treatment strategy. According to the Journal of Diagnostic Medical Sonography, a diagnostic medical sonographer is an individual who provides patient care services utilizing ultrasound and related diagnostic procedures. In addition, the Journal of Diagnostic Medical Sonography states a diagnostic medical sonographer is a multi-specialty profession comprised of many diverse emerging clinical areas (Bendick, P.
Often times we may ignore the signs our body is trying to tell us. Mainly due to fear of the unknown. Our kidneys play an important role in our body. They are used to filter out waste through urination. There are many exams that physicians use to help diagnose renal failure and there are some less commonly used because they have no effect of diagnosis of renal failure. Ultra- sounds are the number one imaging modality to help in diagnosing renal failure and angiography of the kidney is the least used imaging modality. In order to prevent our body from shutting down it is imperative we pay attention to the signs of what our body is trying to tell us.
Diagnostic Medical Sonographer program matches my intelligence for several different reasons. The Anatomy and Physiology of the human body intrigues me just thinking about how the different organs, bones, and systems work. My deep interest in this area is one of the many reasons I decided to pursue a career in this field.
I am still stuck between if I want to continue my education beyond Piedmont Virginia Community College. My field of study is sonography. With this program all you really need is an associates of applied science degree. If I feel I want to move up in this field I will further my education. My ideal University would have to be located in a small or medium size city. I am searching for a school that has all the right educational tools to help me through my program of study.

Today, fluoroscopic contrast examinations (X-ray enteroclysis and X-ray small-bowel follow-through), to whom we owe all the semeiotics of this disease, are increasingly less preferred over other imaging modalities that show better extramural alterations and complications. In fact, some extramural alterations and complications have been the most important limitations of the conventional radiological examination. CT enterography and MR enterography (MRE) exceed these limits, but they have disadvantages attributable mainly to ionizing radiation in the first case and the need for sedation or claustrophobic troubles in the second case. MRE still has other disadvantages, such as long acquisition times that require an effective collaboration of the patient, the high cost and limited availability of the instrument in hospitals.
Effective management of pain intensity among non-verbal or pre-verbal children during sonography procedure is considered as a major challenge regarding its pervasive diagnostic value in pediatrics clinical care setting. Evaluating current behavioral scales and identifying risk factors associated with pain and collaboration scores may help to identify functional coping
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. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
