What is Ultrasound? 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
echocardiography) Without the use of physics the medical equipment, such as X-rays, ultrasounds and endoscopes, would not exist. This would cause diagnosis of patients to be a long and complex procedure. This equipment has revolutionised medical practise and will continue doing so for years to come.

subsequent, and health ultrasound mechanisms use waves alongside a frequency fluctuating amid 2 and 15 MHz.[2] The velocity of ultrasound in a specific medium equals the frequency of ultrasound increased by its wave length.[1] Go to: BASIC PHYSICS Medical ultrasound mechanisms produce ultrasound waves and accord the imitated echoes. Brightness mode (B mode) is the frank mode that is normally used.[2] The B mode gives a two dimensional (2D) black and white picture that depends on the anatomical locale

Executive summary Constructing and programming of robot vehicle that can avoid the barriers depending on calculations of the exact distance between the barrier and vehicle using ultrasonic sensor fixed at the top of vehicle which contact with stepper motor to enable sensor turn right and left will be discussed and applied practically. The functions of constructed robot can be summarized as avoiding barrier, changing velocity of robot depending on the range distance between vehicle and barrier, lighting
hold awkward positions to work around a patient that is unable to move, and scanning itself is physical. The physicality of scanning is often the reason why the ultrasound field is commonly plagued with many musculoskeletal disorders. The diagnostic medical sonography field has a prevalence of musculoskeletal injuries of 81 percent. For this reason it is important to know the proper technique and exercises that can be done to help prevents musculoskeletal injuries. My goal in this paper is to bring understanding
The Process Essay: Undercover of the Ultrasound Machine Today’s ultrasound machines operate using the pulse-echo system. In order to produce an accurate representation of the anatomy being surveyed, the machine must determine echo’s strength and location. Ultrasound systems measure the time it takes for echoes to return and relates that to distance traveled to decipher location of reflectors using the range equation. Ultrasound equipment basically consists of four components, a beam former, receiver
Choosing this field is something that has a profound connection with my personal life. Becoming a Diagnostic Medical sonographer would mean that I have accomplished life long dream. Ever since I was a little, I always wanted to be in the medical field. I have always had a big heart and wanted to help people so when I saw the important role that sonographers play in the medical field, it became clear to me that being a sonographer was exactly what I want to do with my life. In 2007 someone who was
Doppler radar Meteorologists and weather analysts use the Doppler Effect to read weather events. In this case, the fixed transmitter is located at a weather station and the moving object being studied is a storm system. This is what happens: 1. Radio waves are emitted from the transmitter at the weather station at a specific frequency. 2. The waves are large enough to interact with clouds and other atmospheric objects. The waves strike the atmospheric objects and bounce back toward the receiver at
Ultrasounds are an important feature of technology used in our world today. The medical world uses ultrasounds and x-rays on an everyday bases. Ultrasounds are high-frequency sound waves and ultrasounds also produce sound waves that are beamed into the body causing return echoes that are recorded to visualize structures beneath the skin. Ultrasounds have thousands of different types and help doctors and patients see specific diseases and conditions that they cannot see otherwise. However, even though
distributed over both feet (HSA, 2014). If chair height cannot be adjusted, a cushion should be added to sit on to obtain desired height in addition to providing lumbar support (Coffin, 2014). There are chairs designed specifically for Diagnostic Medical Sonographers, chairs that are built to suit ergonomic needs and MSI prevention (Sound Ergonomics, 2014). The HAG Capisco (figure 5) is a chair that can accommodate different sitting positions while providing proper posture support. The HAG Capisco
The constantly growing field of medical technology has raised many questions especially pertaining to ethics. The mapping of the human genome, cloning technologies, stem cell research, and of course reproductive technology has caused some very real dilemmas over the role of the human decision in the creation and orientation of new life. Humans are able to accomplish amazing things in science, but at what cost? The ubiquitous nature of reproductive technology has caused a new discipline of reproductive
I am currently in the Washington Army National Guard and love the leadership skills it has given me. Over the last five years of being in the guard, I have been given many leadership opportunities; such as being the shift lead for the airfield while on deployment. We worked with many militaries from all over the world; communicating the flight plans for the day and ensuring that everything ran smoothly. While in high school, I had the amazing opportunity to be a teacher’s assistant in the lifestyles
traumatizing,” she rambled on. “Have you ever thought about a career In the medical field?” Jenny asked me. “I 'd sure like to look into it,” I responded. She begins again, saying “I started out as a nurse and it is the most rewarding job, if you enjoy helping people I’d consider looking more into it.” While I 'm exploring the rest of the career fair talking about the medical field with Jenny has me interested to find out which medical
Medical Sonographer, a career that uses ultrasound equipment to look along with testing parts of a patient's body, is a career I wish to pursue for the social skills I will gain, the amount of pay I will earn, in addition with the work setting I will be in. I have been wanting this career scene I was in sixth grade. What got my attention about this career is meeting as well as becoming close to my patients. The challenges I am concerned about this career is if the patient had a miscarriage. I want
Nina Wellman Russell Ultrasound Technician I’m very interested in going to school and studying to be an ultrasound technician. This position varies depending on what location you work at. In a hospital setting it can vary anywhere from looking at the stomach,heart,liver,joints,muscles,tendons and blood vessels. How the ultrasound machine (sonogram) works is it’s high rate sound waves to detect what’s going on in the body, not only on humans but

3D/4D ultrasounds. While the equipment used for 3D/4D is different from that of 2D, the ill effects of the ultrasound remain the same. Because ultrasound is a form of energy with effects in the tissue it traverses, its use should be restricted to medical indications by trained professionals for as short a period of time and at as low an intensity as compatible with accurate diagnosis.₁ Obstetric ultrasound may produce biologic changes though thermal mechanisms. This refers to a rise in temperature
Ultrasounds also known as ultrasonography is an imaging technique that uses high-frequency sound waves to make pictures of structures that bounce off internal body parts to create images for medical purposes. This high pitch frequency cannot be heard by the human ear. Over the years, these noninvasive procedures for the most part have replaced the invasive surgery. These procedures cause the patient less trauma and a lower risk of complications that could arise from the alternative surgery. Most
