As an ultrasound tech, you’ll play an important role in helping detect and diagnose medical issues in patients so they can get proper treatment or care.
Ultrasound technologists — also referred to as ultrasound technicians, sonographers, and diagnostic medical sonographers — operate specialized equipment that uses high-frequency sound waves to produce and record images of the inside of a patient’s body (e.g., organs, tissues, bodily masses, blood, and blood vessels).
If you’re interested in pursuing a career in sonography, this career guide provides a breakdown of the steps you’ll need to become an ultrasound technologist in California. Before we dive into the requirements for entering this field, we’ll discuss what the role of an ultrasound technologist entails.
What Does An Ultrasound Tech Do?
Requirements for Becoming an Ultrasound Tech in California
Get Started on Your Ultrasound Tech Education
An ultrasound tech’s job involves operating imaging equipment, conducting scans, and recording diagnostic images and related information. These professionals are also responsible for interacting with patients and ensuring they’re set up for a successful imaging experience.
According to the California Employment Development Department, some duties of diagnostic medical sonographers (or ultrasound tech) include:Whether you’re taking a scan of a mass discovered in the patient’s body or providing an ultrasound for an expectant mother, your work as a sonographer is essential for helping that patient obtain the answers and care they need.
Now that we covered the role of an ultrasound tech, we can explore the steps that are needed to begin working in this role.
To become an ultrasound tech, you will need to earn an associate degree or a postsecondary certificate, though many employers in California prefer candidates with an associate degree.
Ultrasound tech programs typically cover subjects like anatomy, physiology, medical terminology, patient care, laws and ethics related to imaging, and specialized areas within sonography such as abdominal, vascular, and obstetrics imaging.
A strong ultrasound tech program should also provide hands-on clinical experience as part of its requirements for graduation. It should also help prepare students to sit for their national certification exam in sonography, should they choose to become certified.
American Career College offers a 20-month Ultrasound Technologist program in California delivered in a blended format, combining online coursework, on-campus instruction at our Orange County campus in Anaheim, and real-world clinical experience. The program is designed to prepare students to sit for the American Registry of Radiologic Technologists (ARRT) certification exam in sonography.
Associate programs typically take anywhere from one to two years to complete while certificate programs are usually shorter. ACC’s streamlined ultrasound tech program takes 20 months to complete.
While certification is not required to become an ultrasound tech in California, it can be helpful as there are employers that require or prefer certification. You can pursue initial ARRT certification in sonography through the registry’s primary eligibility pathway.
Primary sonography certification requires you to:
Here’s what you need to know about the ARRT sonography certification exam, as outlined in the 2026 Primary Eligibility Pathway Handbook:
If you prefer a more specialized credential, you also have the option to pursue a vascular sonography certification (vascular sonography is imaging of blood flow in the arteries and veins) through ARRT’s primary eligibility pathway. Vascular sonography is also available through the postprimary eligibility pathway as a secondary certification.
If you’re already certified and registered as a sonographer, a radiologic technologist (i.e., you’re an RT who wants to specialize in sonography), or even another professional in a related field, you may want to pursue an additional sonography-related certification through ARRT’s postprimary eligibility pathway. This can help you expand your skill set and career options as an ultrasound technologist.
Here are some advanced certification options that are available through the ARRT:
| Sonography Certifications Through the Postprimary Eligibility Pathway: | Must already have existing certification in one of the following: |
| Breast sonography |
|
| Vascular sonography |
|
* Supporting credential may be earned through ARRT or NMTCB
** Supporting credential may be earned through ARRT or ARDMS
*** Also requires an active credential in Mammography
It should be noted that vascular sonography can also be pursued as a primary eligibility pathway (as an initial ARRT certification).
The ARRT’s certification requirements under the postprimary eligibility pathway include:You can learn the exact requirements for your desired credential by exploring the ARRT’s postprimary eligibility pathway requirements page.
To keep your ARRT certifications and registrations current, you will need to:
Keeping your credentials up to date helps you to continually demonstrate your specialized expertise, and it may be necessary for certain positions that require certification as a requirement for employment.
If you’re at the start of your journey, the first thing you’ll need to do is find an ultrasound technology or sonography program in California that aligns with your needs and puts you on the right path for certification.
