Cardio sonography technicians are specialized in the creation of high-frequency sound waves to diagnose problems that arise in the cardiovascular system. Early diagnosis of cardiovascular problems are the most crucial part of preventing more significant health problems down the road.

What Does the Sonographer Do?

The cardiac sonographer sends sound waves that bounce back and are collected by the equipment and is then converted into a signal that is projected onto a viewing screen. The sonographer is familiar with various techniques, including the Spectral Doppler, Color Doppler, 2-Dimensional and M-Mode. The sonographer must not only know how to operate the equipment, but must also understand human anatomy well enough to use the equipment effectively.

Benefits of the Sonography 

The test requires thirty minutes and is non-invasive. The physician does not have to make an incision and the patient does not suffer any negative side effects from the procedure. The tests are often performed when the physician is in a different room and the physician must be able to trust that the sonographer will perform the tests correctly. Without accurate images, the physician might form an incorrect diagnosis which would prevent the physician from successfully treating the condition and may lead to the physician using treatments that might be harmful to the patient.

The Career Prospects for a Sonographer are Bright

The career of a cardiac sonographer is a potentially lucrative career because there is a shortage of well-trained cardiac sonographers and a growing need for them. As many adults age and begin to experience more age-related disorders, they will need more extensive screenings to identify harmful cardiovascular diseases.

Programs Offered for the Sonographer


Given that the need for cardiac sonographers is growing, many universities are offering programs designed to teach students the skills that are necessary to succeed in this career including Sanford Brown College. Many universities already have a program in ultrasound but have found it necessary to expand their programs to offer courses focused specifically on the use of sonography. The Journal of Ultrasound in Medicine recently released a journal article entitled “What it Means to be a Cardiovascular Sonographer” to give students a background in the profession.

To become a sonographer, most students need at least a 2-year associate’s degree. In some cases, a 4-year bachelor’s degree is ideal. Students who choose to pursue the 4-year bachelor’s degree will be more likely to find a position than those who hold an associate’s degree. Additionally, some states have mandatory licensing requirements. Employers also sometimes require certification that typically requires that students participate in classroom instruction and take exams.

Career Data for Sonographers


The United States Bureau of Labor Statistics (BLS) collects data on various careers including the diagnostic medical sonographers profession. The BLS predicts that medical facilities will try to protect their patients and lower costs by using the ultrasound procedure rather than using more invasive and potentially harmful diagnostic procedures, such as the x-ray. As a result, the need for sonographers is expected to grow by 44 percent between 2010 and 2020.
