Invention of ultrasound?
Ultrasound very first time was used for medical purpose in year 1956. Glasgow was place where it's saying it's first light. It was used in Glasgow by an obstetrician named Ian Donald and an engineer named Tom brown. They were the first people who crafted the prototype system. For ultrasound but it wasn't perfected until the end of the 1950s however in the 1970s it became widely used

Ultrasound imaging used High-frequency sound wave to produce picture of the inside of the body. The sound waves make echoes that form picture of the tissue and organs on a computer screen. compared with other modalities such as conventional radiography or CT ultrasound may be used to help diagnose diseases, such as cancer it may also be used during pregnancy to check fetus in pregnant women. In infants, doctors commonly use ultrasound to evaluate the brain, hips, and spine. It also helps guide biopsies, diagnose heart conditions, and assess damage after a heart attack. Ultrasound is safe, noninvasive, and does not use radiation.

Why ultrasound performed?

An ultrasound can provide a view of the:
  • bladder
  • brain (in infants)
  • eyes
  • gallbladder
  • kidneys
  • liver
  • ovaries
  • pancreas
  • spleen
  • thyroid
  • testicles
  • uterus
  • blood vessel's

ultrasound is also very helpful way to guide surgeonsí movements during certain medical procedures, such as biopsies.

Preparation of ultrasound?

Some ultrasound doesnít need preparation, there are few exceptions
  • For some scans, such as a gallbladder ultrasound, your doctor may ask that you not eat or drink for certain period of time before the exam.
  • In pelvic ultrasound you may require a full bladder. Your doctor will let you know how much water you need to drink before the exam. Do not urinate until the exam is done
  • Children: Do not eat or drink four hours before study or skip one meal.
  • If you are diabetic, please take your insulin.
  • leave jewelry at Home at wear loose, comfortable clothing and need to change into gown

How ultrasound performed?

An ultrasound habitually includes the following this steps:
  • ultrasound Technician will guide you to change into a hospital gown. You will most likely be lying down on a table with a section of your body exposed for the test
  • A health care provider will spread a special gel on the skin over that area
  • This prevents friction so they can rub the ultrasound transducer on your skin.
  • The device will send sound waves into your body. The waves are so high pitched that you canít hear them.
  • The waves echo as they hit a dense object, such as an organ or bone. Those echoes are then reflected back into a computer
  • You will be able to view the images as they are being made. This frequently happens during a pregnancy ultrasound, will allow you to look at your unborn baby.
  • After the procedure, the gel will be cleaned off of your skin.
  • The test will take about 30 to 60 minutes to finish

Ultrasound risk:
Because ultrasound uses sound waves instead of radiation, itís safer than X-rays. Mainstay have used ultrasound for more than 30 years, and they have not found any dangerous risks. Ultrasound is a valuable tool, but it has limitations. Sound doesn't travel well through air or bone, so ultrasound isn't effective at imaging body parts that have gas in them or are hidden by bone, such as the lungs or head.
