Membership Organizations That Sound Health Imaging Is Affiliated With

Quality ultrasound imaging is extremely sonographer dependent, therefore, Sound Health Imaging, Inc. employs only ARDMS (American Registry for Diagnostic Medical Sonography) certified sonographers. Sound Health’s formally trained staff are among the most qualified in Montana having multiple certifications in Abdominal, Cardiac, Obstetrical/Gynecology, and Vascular Ultrasonography. Annual continuing education at conferences and labs across the United States is a requirement for continued ARDMS certification and ensures that sonographers are current with the state of the art research and techniques. Our sonographers are also certified with the Fetal Medicine Foundation to perform Ultrascreens to assess nuchal translucency thickness and absence or presence of nasal bones in first trimester genetic risk assessment.

To be eligible for a RDMS credential, Sonographers must first meet specific educational and professional experience requirements. Once these requirements are met, the aspiring Sonographer is allowed to take the boards exam. The RDMS credential requires successful testing in Ultrasound Physics and successful testing in at least one specialty area, such as Abdominal, OB/GYN, or Breast. The RDCS credential requires successful testing in Cardiac Ultrasound Physics plus successful testing in any of the following specialty areas: Adult Echocardiology, Pediatric Echocardiology or Fetal Echocardiology. The RVT credential requires successful testing in Vascular Physics and Vascular Implementation.

Unfortunately, the state of Montana has no laws requiring those performing ultrasound to be registered. Many facilities do not require their sonographers to be registered. However, Sound Health Imaging only employs registered sonographers!

American College of Radiology

Sound Health Imaging has gone to the extraordinary measure of achieving and maintaining ongoing professional accreditation at both Helena & Butte facilities by the American College of Radiology. Sound Health’s are the only accredited ultrasound facilities in southwest Montana.


The Fetal Medicine Foundation

Sound Health’s ultrasonography staff are required to become certified with the Fetal Medicine Foundation in order to perform the 1st trimester ultrasound screen for Down’s Syndrome. Staff has ongoing continuing certification requirements that must be met in order to maintain their individual certification.


American Registry for Diagnostic Medical Sonography (ARDMS)

The ARDMS is a certification body (an independent, nonprofit organization) that administers examinations and awards credentials in the areas of diagnostic medical sonography, diagnostic cardiac sonography, and vascular technology. 
The three credentials offered by the ARMS to eligible candidates are:

  • RDMS Registered Diagnostic Medical Sonographer
  • RDCS Registerd Diagnostic Cardiac Sonographer
  • RVT Registerd Vascular Technologist

As a certifying body, it is the responsibility of the ARDMS to promote the continuing competency of its registrants. To meet the continuing competency requirements of the ARDMS, registrants must accrue continuing medical education (CME) credits. To maintain eligible status, registrants must accrue 30 CME credits per three- year period. For information on certification examinations, submission of continuing medical education credits, or matters related to registry status, contact the ARDMS.
