Ultrasound: Dalymar Legrand

I. Introduction

(Figure 1)

Ultrasound is an imaging technique that provides that ability to medical practitioners. Ultrasounds are use to look inside your body. It is usually done to see your baby. Ultrasounds send out sound waves inside your body causing whatever is inside to return echoes. Those echoes are then recorded to a visualize structures beneath the skin. The visualized part is measure by the echoes reflected. This instrument is mostly accurate at seeing the interface between solid and fluid spaces. You can relate to this to the sonar on boats to see the bottom of the ocean.

II. Development

Ultrasounds can be use in many ways. But the most used are for obstetrics, echocardiography and abdominals structures. In the obstetrics they simply look for the progression of pregnancy. The ultrasound can be done two ways; trans-abdominally where the probe is placed on the abdominal wall or trans-vaginally, where the probe is placed in the vagina. The diagnoses that you can obtain from this are the growths or tumors of the ovary, uterus, and Fallopian tubes.

In the echocardiography it is use to check the heart of the baby, heart’s function, and blood flow. It is so cool that it shows you the amount of blood the heart pumps with each stroke. This process can also be done in two ways; trans- thoracic, the probe is place on the chest to obtain images or trans- esophageal, where the probe is placed through the mouth into the esophagus. The last way can is more invasive.

And last abdominal structures can evaluate the liver, gallbladder, pancreas, kidneys, prostate, testicles, uterus, and ovaries. This ultrasound may find:

· Stones as well as signs of infection in the gallbladder.

· Are use to look for diseases like appendicitis or Kidney stones.

· To diagnose testicular torsion.

· Can also be use for non- pregnancy related like abdominal pain, uterine growths, and ovarian cysts.

III. Biography

William Nelson Beck was the man who invented ultrasounds. During his adulthood he was willing to fix things and people related to him as a gadget man. He was a navy pilot in World War II and event here was called the “Cadet Gadget.” He will be inventing things that could help his friends and he did so many things that saved their lives. A good achievement was the development of Mae West which at first had to be inflated by the pilots before it hit the water and thanks to the help of Nelson, it inflated manually as soon as it hit the water. After the war he went to assist at the University of South Dakota. Later on he became a physicist and by 1957, discovers the ultrasound. His neighbors always remembered him as a kind man and his enjoyment of life. Nelson died in June 16, 1996, at the age of 72. He was a modest man that no even his son knew about his early discoveries. It was not until his wife was pregnant and was going to get an ultrasound that he declared to his son that he discovered ultrasound.

IV. Impact on Human

The impact on the world is the risk and benefits that most women get from getting an ultrasound. Some of the benefits are:

· It isn’t painful.

· Is easy to use and easy to pay.

·Doesn’t use ionizing radiation.

· Gives clear images.

· You can obtain the health information of the baby and the woman health.

This is some of the benefits but I believe that from this benefits, risk comes. Most women kill their babies because of what they found out on the ultrasound.

V. Article

People don’t know yet if ultrasounds should be use selective or by routine. There is a difference between these two. To identify fetal abnormality you must go in a routine schedule due to the examination procedure. The selective procedure is done by a specific question about the baby or the pregnancy. It’s so much valuable information that you are getting out of the ultrasound; such as baby’s sex and its abnormality. You can also find out if the baby is alive or death. They also do placental grading in which is associated with increased use of other fetal techniques and a tendency to increased use of elective delivery for fetal compromise. Many obstetric already use practical routine ultrasounds in early pregnancy. The knowledge that you get from those ultrasounds can be an advantage to the baby’s health and a disadvantage for them is they are abnormal. During ultrasound examinations any time in pregnancy, mothers should see the monitor and see a clear image of their unborn and receive information that they desire.
