Sound waves can be directed into the body to produce high-quality images of  various organs and systems. Sonographers, also known as ultrasound  technologists, are the 
medical professionals who operate  the equipment which generates these images. The U.S. Department of Labor's  Bureau of Labor Statistics notes that as the population ages, the demand for  imaging services is increasing. More than 9,200 new jobs will be added through  the year 2018, making employment opportunities favorable for aspiring ultrasound  techs.
Choose a training program. The Bureau of Labor Statistics reports that a  certificate is appropriate for those with prior 
health care  experience. Individuals with no prior health care experience are advised to  enroll in an associate or bachelor's degree program. As an ultrasound technology  student, you will take courses in in anatomy, medical terminology and physics  and instrumentation. You will learn how to  perform sonograms of the abdomen and  chest, as well as obstetric sonograms. Sonography programs are approved by the  Commission on Accreditation of Allied Health Education  Programs.
 
- Apply for the certification exam  administered by the American Registry of Radiologic Technologists. Candidates  for sonography certification must be graduates of an accredited training  program, and the certificate or degree must have been earned no more than five  years before taking the certification exam. The 360-question exam includes  patient care, sonographic procedures and ultrasound principles. You are allowed  three attempts to pass the exam within a three-year period.
 
- Maintain your certification by registering with the American Registry of  Radiologic Technologists. Registration must be completed on an annual basis.  Certified ultrasound techs can use the designation of R.T., or registered  technologist. In addition to registration, which can be completed via mail or  online, certified ultrasound techs must earn 24 continuing education credits  each year. Acceptable forms of continuing education credits include college  courses and advanced CPR certification.
