Ultrasound imaging; a painless procedure to discover human physiology
Ultrasound, otherwise known as sonography is considered as a step ahead in medical technology. This includes safe and painless procedure generating pictures of body organs with the use of sonic waves. There is the use of a probe in the form of a small transducer and even an ultrasound gel is used on the skin.
Discovering ultrasound technology:-
1. Defining Ultrasound:-
In simple and clinical term, ultrasound technology is a kind of imaging science where the internal organ pictures are captured and generated. This is done best with the use of high-frequency sound waves to visualize organs and structures inside the human body. Mostly the procedure is done regularly at preferred time intervals.
This is referred by health care professionals to view cardiac functioning, blood vessels, kidneys, liver and other organs. More specific it is a common and regular process during pregnancy. For pregnant women, doctors prefer the process to view the position and confirm the proper functioning of the fetus. As there is no use of radiations, the procedure is not considered risky.
For conducting the test in case of pregnant women or any other patients:-
•The doctors would first ask the patients to have a stomach full of water to retain the water content inside the body.
• Then the patient when feels like urinating, they are asked to lie on the table. Then the ultrasound gel is placed directly on the skin.
•The gel here acts to transmit the high-frequency sound waves from the probe into the body.
•Then the transducer is moved over the body part which is to be examined.
•This is going to capture the waves that bounce back and the ultrasound machine is going to create images from the sound waves.
Ultrasonic waves used in sonography:-
These ultrasonic waves used during sonography are sound energy which is generated in the form of waves having a higher frequency above the range of human hearing. For medical diagnostics or sonography, the ultrasound scans extend to 10 MHz and above that. This would capture the functioning of the organ and transmit it back which will be reordered and an image would be generated further.
This is to measure the distance with the use of ultrasonic waves. The ultrasonic sensor as a device is attached with a head that emits ultrasonic waves and receives the reflected waves back from the target. The sensors are generally used for measuring the distance to the target by measuring the time between the emission and reception.
