From General DMS to Telemedicine, learn what Sonographers do every day

An ultrasound technician’s job description includes much more than operating imaging equipment.  These healthcare professionals use diagnostic ultrasound to capture high-resolution images of internal organs, blood flow, and fetal development.  They also work closely with patients, physicians, and the clinical care team – offering guidance, emotional support, and real-time image analysis during potentially life-changing medical moments.  The role requires both technical skill and strong interpersonal communication, making it one of the most dynamic and rewarding positions in allied health.

What Does an Ultrasound Technician Do?

An ultrasound technologist, also referred to as a sonographer or diagnostic medical sonographer, does more than just operate imaging equipment. They balance patient interaction and technological performance with a firm knowledge of anatomy and pathology by working cohesively with a healthcare team.

Sonographers use imaging equipment that non-invasively emits sound waves directed towards internal organs, blood vessels, tissues and other structures in order to detect abnormalities. A sonographer’s job description entails using this specialized technology as well as assisting physicians and other members of the healthcare team with interpreting images. Sonographers also work directly with patients by preparing them for procedures and keeping track of their history. While ultrasound technicians work in a variety of locations such as hospitals or imaging clinics, their general job duties are consistent:

Essential Job Duties and Requirements

• Perform ultrasound procedures, ensuring the transducer (probe) captures high-quality images for accurate diagnosis.
• Clearly explain the ultrasound process to patients, addressing any questions to help ease concerns.
• Maintain and calibrate ultrasound equipment while ensuring a sterile and safe imaging environment.
• Apply ultrasound gel to the designated area for optimal image clarity and patient comfort.
• Assess image quality and make real-time adjustments to enhance diagnostic accuracy.
• Present images and preliminary observations to physicians and collaborate with the healthcare team.
• Accurately document patient records and include relevant medical notes from the ultrasound procedure.

Physical Requirements

Diagnostic medical sonographers must be both technically skilled and physically resilient. Most positions require you to lift or assist patients weighing up to 50 pounds, stand for long periods, and perform repetitive scanning motions throughout the day. In many clinical settings, sonographers also adjust heavy equipment, bend frequently, and reposition patients during exams.

The result? A high rate of work-related strain. According to the Society of Diagnostic Medical Sonography (SDMS), up to 90% of sonographers experience musculoskeletal disorders (WRMSDs) over the course of their careers. These injuries often affect the neck, shoulders, wrists, and lower back. In some cases, they can be severe enough to shorten or end a professional career.

Preventing injury starts with awareness. From proper posture and ergonomic scanning setups to stretch routines between patients, small adjustments can make a big difference.

What Skills do Sonographers Need to Have?

Healthcare professions and other service industry related careers require a wide-range of skills, from technical know-how (commonly known as hard skills) to good interpersonal communication (the soft skills). In order to be a successful and well-rounded sonographer, it’s necessary to have both.  Hard skills represent the abilities a professional must be able to do to accomplish their job. Soft skills are the abilities a professional must utilize when carrying out the hard skills.

A Closer Look at Sonography

Diagnostic vs. Therapeutic Ultrasound

Ultrasound techs are trained to identify normal anatomical structures as well as detect structural and functional abnormalities. For example, a vascular sonographer may detect a blockage of blood flow to a patient’s brain which would explain their recent stroke symptoms. This type of ultrasound is known as diagnostic ultrasound.

Ultrasound can also be used therapeutically in the treatment of disease, known as therapeutic ultrasound. This involves directing energy into tissues, nerves, and other aspects of the body in order to produce beneficial physiological effects. For example, a physical therapist may use ultrasonic technology to treat a patient with a musculoskeletal injury.

Medical Imaging Modalities

Ultrasound technicians differ from radiologic technicians who perform X-rays, MRIs and CT scans in that their equipment employs sound waves instead of radiation. Despite this difference, their work often compliments one another. For example, a radiologic technician will often take a mammogram of the breast in conjunction with a sonographer performing an ultrasound.

A sonographer’s job description varies depending on where they work. According to the Bureau of Labor Statistics (BLS), the majority of diagnostic medical sonographers worked in hospitals. In a hospital setting, 12 hour shifts are not uncommon, and a sonographer can expect an average of 12-15 patients in a day. Sonographers will work closely the healthcare team, receiving referrals from physicians and reporting any concerns back immediately.

Sample Ultrasound Technician Job Postings

Job descriptions and postings vary, depending on the employer and specialty involved. As follows is an example of a typical job posting, describing the professional tasks of the sonographer to be hired:

Seeking Diagnostic Medical Sonographer

• Responsible for performing all ultrasound procedures including those within the department, at the bedside, and in the OR.
• Works closely with the radiologist and other licensed physicians presenting images and data for interpretation and assisting with interventional procedures.
• Shows independent judgment when performing procedures and when addressing difficult or unusual situations.
• Responsible for evaluating images for technical quality.
• Utilizes PACS (picture archiving and communications system) with accuracy.
• Accepts additional assignments and tasks as needed for the department.
• Provides ultrasound department coverage after hours when participating in on-call rotation.
• Assesses patient to determine ability to undergo requested examination.

Emerging Opportunities

The field of medical imaging is constantly changing, with new technology bringing new opportunities. Here are just a couple of the emerging fields within diagnostic medical sonography.

Traveling Sonographer

A number of ultrasound staffing agencies give sonographers the option to take their vocation on the road.

Traveling ultrasound technicians generally work on short term contracts, filling in for sonographers who go on maternity or sick leave, vacation, or extended leaves of absence. It’s a great experience for ultrasound techs to experience different parts of the country and a variety of workplaces.

Reputable staffing agencies should cover travel, housing and per diem expenses. Additionally, traveling sonographers often earn more during their contract than they would working the same period as a permanent employee, and the work schedule tends to be more flexible.

Telemedicine

Telemedicine involves two or more healthcare professionals, who are in different geographic locales, sharing medical information via electronic or telecommunications.  What was once a rarity is becoming commonplace due to the need to reduce the spread of Covid-19.

Ultrasound technologists play an important role in telemedicine. At a rural hospital or health center, for example, there may be limited times when a specialized physician, like a cardiologist or gastroenterologist, is actually on site. In these situations, sonographers and other medical imagers can work directly with patients at the facility and communicate their findings with the appropriate physician via telemedicine.

Getting Started on a New Path

Numerous colleges and universities offer ultrasound degree programs that will provide aspiring sonographers with the theory and practice (through labs and clinical internships) they need to be a successful medical sonographer.

Before applying for a program, it’s important to ensure it will qualify to you to become certified through the ARDMS (American Registry for Diagnostic Medical Sonography), a credential heralded by the American and global medical community.
