Also, the Bodyscope is a very practical device. Unlike state of the art devices that needs to be worn around the wrist, attached to phones or integrated with cameras; the Bodyscope latches directly with the part of the body responsible for sending out these acoustic signals, that is, the neck or throat. 4. What assumptions are the authors making?
Ultrasonography, commonly referred to as Sonography, is a diagnostic medical procedure which utilizes high frequency sound waves (ultrasound) to produce
Ultrasound technology uses high frequency sound waves as opposed to x-ray technology that uses radiation. Because of this there are minimal risks posed to the mother and the baby. The main reasons for risks being more pronounced will be if the equipment used is extremely old or faulty, or if the sonographer does not have the right experience or training to complete the
“Let’s terminate the pregnancy and start again next month’” (Collins 167). It took a couple minutes to process the words I just read because the doctor made it sound like being pregnant was equivalant to writing the wrong word in pen. Pregnancy is actually pretty complicated when you put it into perspective because about it, there is another life being created inside a woman’s body. It just amazes how incompetent some people can be.
Diagnostic imaging is used every day all over the world and is growing rapidly. It is used in the hospital, OB/GYN offices, outpatient care centers, medical and diagnostic laboratories, and physicians’ offices (Cross, 2017). A diagnostic medical sonographer utilizes special equipment with sound waves to generate images. These images are used for assessing and diagnosing various medical conditions (Diagnostic, 2016). When most people hear the word sonography they think of pregnancy.
Internal Imagers “Megan”, said Shanna holding a clip board with the patient’s information. As soon as the lady walked toward her, she admired the smiled that crossed the lady’s face, the joy her eyes had with her big belly in the way of her being able to walk right. Shanna was excited to see the patient once again with her husband because she knew they appreciated that she took care of what she was supposed to do, and let them know how their baby was doing. She took them to the room and checked how the baby was doing, in that moment Shanna realized how important her job was because she was excited to see the faces of the parents of an unborn child when she would tell them the gender of the baby. At the moment when she said
I am a twenty-three year old mother, full-time student and wife. I have come a long way since my high school years, from a period of inner conflict and lack of motivation to recently receiving an acceptance letter into a very competitive sonography program at the University of Texas School of Health Professions in Houston Texas. I have come to this program to start a career in the field I have always dreamed of being a part of, a dream that began when I was a child playing nurse. Although my interest in the medical field began with nursing, life has taken men through a path that lead me to sonography. Sonography caught my interest at sixteen when I needed a breast exam to diagnose whether I had breast cancer or not
What is The Future of Sonography? Sonography, also known as Medical ultrasound has constantly gained importance in the medical field since its invention over 30 years ago. Today, significant strides have been achieved in improving the efficiency and availability of ultrasound services so that radiologists can perform critical operations remotely preventing number of preventable deaths. The future looks promising with more advancement expected in terms of increasing the scope of procedures and also treatment capabilities.
So, say you're experiencing knee pain. The person treating you looks at a diagram of a fetus that's upside down and sees where the knee is located. Then he would locate where that spot is on your ear.
These waves traverse into your body and reach a border between fluid and soft tissue, or soft tissue and bone. At the same time, some travel further until they reach a different boundary and get reflected back. Consequently, the redirected waves are picked up by the probe and are imparted to the machine. Furthermore,
Although background information proves that ultrasound is a relatively safe and effective imaging tool there are still some complications during the procedure. Sonography is a safe and effective imaging tool, but the machines, “do not present this information in a manner that is easily accessed or understood by the operator” (Alexander 19). Ultrasound imaging can be difficult to understand because the procedure uses little to no radiation, for penetrating thick layers of human tissue can be difficult. Shallow penetration of human tissue leads to a poor quality images; making images hard to characterize or diagnose. A Major difficulty in ultrasound is most of the, “information on biological effects of ultrasound on humans is undiscovered” (Alexander
The transmitted pulses are reflected by the target and then received by the same radar. The reflected energy or the echoes are further processed to extract target information. 4 5 Explain how ultrasound works and why it is useful. Provide at least 2 examples of its use today. [5 marks] Ultrasound is a medical imaging technique that uses high frequency sound waves and their echoes.
The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.
Whether you are reading notecards while performing an ultrasound or have someone call questions out to you, you are always learning new ways
Sound could be differentiate into two types, infra (audible) and ultra (inaudible) sound. Ultrasound waves have a frequency above the normal range
