Ultrasounds date all the way back to the year 1958. Ultrasounds use noninvasive waves, that go through the body, so others can see inside of that person’s body. One of the amazing things about ultrasounds, is that they have a frequency of 20 kHz of 20,000 Hz. This paper will talk about what ultrasounds are, how we use them, what is the application of an ultrasound in medicine, how each part works in the ultrasound machine. Another thing that this paper will be talking about, would be why ultrasounds use sound waves, what is a sound wave, and how sound waves reflect back.
Ultrasounds, also known as ultrasound or sonography, is a type of moving sound pressure wave. An ultrasound is a safe and painless procedure that allows us to see through the layers of skin of to see a person’s anatomy. Most ultrasounds are done using a sonar device outside your body, sending waves into your body. Though, some devices are used for the inside of your body.
An ultrasound sends out high frequency sound waves, that are directed at the part of the body that is being looked at by the doctor. Then, these sounds/echoes are then recorded to make a two-dimensional image. Gel is placed on a patient’s stomach to create better contact between the skin and the transducer. The doctor then, puts the transducer to the stomach (or …show more content…
When a sound reflected off of a curved object, it will bounce off in a straight line no matter what. So when the sound wave hits and internal organ, the wave will come back in a straight line. Mechanical vibrations produce the sound wave. Sound waves have high and low pressure areas, called condensations are rarefactions, which categorises this wave as a mechanical wave. The particles in the wave move parallel to the velocity of the wave. It is possible to determine how far away the object is, as well as the object’s size, by measuring these echo waves, when they come
