Ultrasound Papers

For the past 70 years, ultrasounds have been continually evolving with both diagnosis and treatment. An ultrasound is a type of diagnostic imaging technology. This technology uses sound waves to develop images based on the internal structures of the body. When the sound waves are being projected from a transmitter attached to the ultrasound and hits tissue, the sound waves reflect and create echoes which create a picture on the screen, the shorter the wavelength, the finer the detail of the picture. This is used to help physicains discover the reasoning of a patient’s pain, swelling and infection. Ultrasounds benefit healthcare immensely because there are different uses for an ultrasound. This technology allows physicians to see issues with

George Ludwig in the 1940s. In 1942, the first medical ultrasound was used by Karl Dussik, he used an ultrasound beam with the intention to locate brain tumors and cerebral ventricles. After this, John Wild, laid the foundations for ultrasound tissue diagnosis’ with the development of the amplitude mode (A-mode) ultrasound. This ultrasound investigates intestinal and breast abnormalities in patients. After the A-mode was created the B-mode was the next ultrasound to be invented in 1955. The B-mode (brightness mode) ultrasound helps with early descriptions of transrectal and transvaginal abnormalities. Later on, Donald Glasgow made a major milestone in medical ultrasounds, he created a flaw detector to differentiate cysts from a solid abnormal mass. All of these developments were within twenty years of the first medical ultrasound. As more advances were made ultrasound machines began to expand and have different

There are numerous reasons as to why someone would get an ultrasound. Typically ultrasounds are associated with pregnancies, however, ultrasounds are versatile and can be used to check different internal structures. There are four different types of ultrasound machines, they are echocardiogram, abdominal ultrasound, duplex ultrasound and obstetric ultrasound. An echocardiogram is an ultrasound of the heart, that shows the function and structure of the heart. The echocardiogram can detect abnormalities in the heart valves of the heart or in the heart muscle. It can also determine how well the heart is pumping blood. An abdominal ultrasound allows the radiologist to see images of the organs inside the abdomen (spleen, liver, kidneys, gallbladder and pancreas). Typically, physcians prefer an abdominal ultrasound over an X-ray because ultrasounds do not use radiation and is a painless process. This ultrasound is used to determine any abnormalities in the abdomen, for example, if a patient has appendicitis. There is also a duplex ultrasound, this machine shows blood flow of major arteries typically in the neck, abdomen, arms and legs. It monitors the direction of blood flow, if there are any abnormalities in the blood flow, like a blood clot. A common place for blood clots is in the legs after a surgery because the patient isn't moving around as much, which can cause severe problems. A duplex ultrasound can detect
