Ultrasound is a repeated sound compression that surpasses the human hearing frequency which is generally regarded to be at 20 KHz but may vary from person to person. These high frequency sound waves have multiple purposes and are often used to enter a particular medium to find the internal movement of the medium by using a similar concept such as SONAR waves. Ultrasound has been used in various fields especially in medical field as it has no known harmful effects when used to penetrate human body.
In medical field Ultrasound technology has been used to view the target organ in human beings by using a device known as transducer that radiates a sound and senses the echoes of the sound produced. The device uses a computer to generate an image of the sound waves that are detected when they bounce back from within the medium e.g. human body. The image is then used to examine the internal function of the medium and its matter e.g. a fetus in a pregnant woman. This technique of medical imaging used by Ultrasound technology has been used for over 50 years and has become one of the most commonly used diagnostic practice in modern medicine as it is not only portable but is also comparatively cheaper as compared to other medical diagnostic tools.
A qualified person who uses Ultrasound technology and equipment to help map the human body’s internal working is known as an Ultrasound technician. An Ultrasound technician uses his/her expertise to help digitize or to create medical imaging of human body such as using the machine on patient’s abdominal area or to inspect the mind or spinal cord as well as eyes and correlating muscles.
Ultrasound technicians also known as Ultra sonographers or Sonographers mostly work in hospitals but may choose to work in other health care facilities or medical and diagnostic laboratories. The Ultrasound technicians mostly choose to work in the areas or department that correlate to their specialty field which may include neurology, musculoskeletal sonography, gastroenterology, ophthalmology, obstetrics as well as echocardiography. Other responsibility of an Ultrasound technician includes preparing the patient before the examination by first informing the patient about the entire procedure and then checking the patient’s medical history before the procedure is performed. The technicians examine the images on the equipment screen as they show up, in order to monitor any abnormalities in the result. The images are often kept as a record for patience medical file. Apart from this the technician is also required to maintain as well as manage the equipment and tools that are required for ultrasound.
In order to become an Ultrasound technician often strong educational background in mathematics, science, and health is preferred however one can get certified as a proper practitioner after completing two to four years of extensive program such as a four year Bachelor’s Degree at a university or two year program at a community college. The most common education or training that an Ultrasound sonographers receive is a two year Associates’ degree.
