Sonography is the use of reflections of high-frequency sound waves to construct images (known as sonograms) of internal body organs. Sonography is applied in varied situations, for instance during the observation of fetal growth and development and studying patients’ internal body organs during treatment. It is essentially a way of taking pictures inside patients through the use of sound waves and their resultant echoes. In more detailed terms it is an ultra-sound based imaging technique that visualizes subcutaneous body structures. When used on pregnant women, it’s referred to as obstetric sonography. It is a very important branch of medicine that people know little about, here are some facts that you need to know about sonography:
The prefix ‘sono’ in sonography means sound and the suffix ‘graph’ means to write, and therefore sonography is art of using sounds to write/draw, of course with the help computerized equipment. Waves with ultra-high frequencies are produced, when they bounce off the surface of an internal organ they produce an echo. Machines known as sonographs are then used to interpret the echoes to produce the image of the organ that made the echo in question. This technique enables doctors to establish the extent of fractures and other injuries on patients, and thus come up with the best treatment procedures.
The word sonography is rarely referred when talking about ultra-sound frequency medical imaging, people often use the terms: ultra-sound technology and diagnostic medical sonography. Sonographers always work hand-in-hand with other medical physicians, by providing them with an avenue of checking for internal injuries, diseases and other medical abnormalities, pretty much in the same way X-ray technicians/radiographers work. However, sonographers are also skilled in the interpretation of the images they produce. As such they analyse the images and hand their reports to doctors for further diagnosis and prescription. Their main role is to operate the machines- sonographs, so as to produce good quality images that will guide doctors in their diagnosis and prescription.
Sonography is a technical field that requires specialized education and skills to perform. One needs to have undergone a specialized educational program at university level to view, analyze and modify scans to make the sonograph images more discernable. There is a high level of decisional latitude and diagnostic input required of them, so they must have a high degree of responsibility in the diagnostic process. In most countries, sonographers are required to have profession certificates and understand ultra-sound physics, cross-sectional anatomy, physiology, pathology and possess good communication skills. As well as develop the psycho-motor skills required in the field of sonography.
Sonography as is with radiography, has several occupational hazards. About 84% of all sonographers complain of experiencing some form of work-related musculoskeletal pain, which has been attributed to them scanning patients in comprised positions, not holding the transducers correctly, and spending a lot of time manipulating the transducers to get proper scans of obese, large pregnant patients and patients who lack upper body fitness. Therefore, it is not that much of a safe profession.
