A specialist in sonography is often referred to as a
diagnostic medical sonographer or an sonography technician. When a healthcare professional
performs sonography on a patient, they use a machine that consists of a
computer, a transducer, and a cord that connects the two. The transducer is
placed on the body and subsequently sends sound waves into the body. These
sound waves are reflected by tissues and received back by the transducer. The
transducer converts the waves into electrical signals which are then sent to
the computer for interpretation. The computer processes the signals and creates
the image that we see on the monitor.
No use of ionizing radiation
There are a few very good reasons for the growing popularity of sonography in medicine. First, sonography does not use ionizing radiation to create images. This greatly reduces the amount of risk that patients and healthcare professionals are exposed to when imaging procedures are performed. Imaging procedures such as x-ray, CT, and MRI place everyone at risk of radiation exposure.
Cost effectiveness
Another reason that sonography has become popular is its cost effectiveness. Compared to other types of imaging, sonography is extremely cheap. While it may cost a few hundred dollars to perform a basic sonography procedure, it may cost many thousands of dollars to perform a CT or MRI. In an age when healthcare costs are out of control, anything that can reduce costs while preserving quality of care is quickly adopted.
Highly mobile
Finally, sonography is highly mobile. CT and MRI require large machines that cannot be easily transported through the healthcare facility. Sonography machines are easy to transport and can be brought to the patient's side wherever they are in the facility. This is extremely important in emergent situations when the difference between life and death is a matter of minutes.
The growing demand for sonography technicians
Along with the growing popularity of sonography in medicine has experienced an increase in the demand for sonography technicians. Sonography is a relatively straightforward career to get into and rarely ever requires licensing. Most sonographers complete a training program and certification before seeking employment. Sonographers also enjoy one of the highest allied health salaries available.
