With the field projected to grow by 11% with approximately 9,400 new job openings for diagnostic medical sonographers and cardiovascular technologists and technicians in the next decade, there's increasing interest in careers within this space.
However, the terms ultrasound technician and sonographer can be confusing for potential students looking to explore these careers. Are they the same, or do they have distinct roles? This article will clarify the similarities and differences between these two professions to help students understand which role may be a more suitable match for their passions and career goals.
What Is an Ultrasound Technician?

An ultrasound technician is a health care professional who uses ultrasound technology to create diagnostic images of a patient's internal organs and tissues. This specialized equipment emits high-frequency sound waves, which bounce off the body to produce images known as sonograms. The goal of the images is to determine an accurate diagnosis of the patient's ailments.
Primary Responsibilities
The primary responsibilities of an ultrasound technician typically include the following:
- Preparing patients for their examinations by explaining the procedure and answering any questions or concerns.
- Programming and adjusting the ultrasound scanner to capture images from various angles and ensuring that the transducer is functioning correctly.
- Performing clinical assessments and diagnostic sonography examinations.
- Selecting and capturing still images that are necessary for diagnostic purposes.
- Assisting with the daily operations of the sonographic laboratory.
- Documenting images and preliminary observations for the physician to review.
In addition to these core duties, ultrasound technicians take care of the equipment, apply gel to improve the quality of the images, and communicate with patients throughout the process. Ultrasound technicians work in various health care settings, such as hospitals, clinics, and diagnostic imaging centers.

What Is a Sonographer?

A sonographer, also known as a diagnostic medical sonographer, is a specialized health care professional who also uses ultrasound technology for diagnostic imaging. However, unlike ultrasound technicians, sonographers focus more on interpreting the results. They provide important information that assists medical professionals in diagnosing and monitoring medical conditions.
Primary Responsibilities
The primary responsibilities of a sonographer include the following:
- Specializing in specific areas such as obstetrics, cardiac sonography, or vascular sonography to focus on specific populations or medical conditions.
- Analyzing the captured images to detect any abnormalities, assisting physicians in diagnosing conditions.
- Supporting radiologists or physicians during invasive procedures, such as vascular ultrasound procedures and ultrasound-guided biopsies.
- Completing necessary documentation and maintaining accurate medical records for each patient, including recording diagnostic data.
