What Does a Cardiac Sonographer Do? Career Path, Salary, and Training in Pennsylvania
If you’re drawn to healthcare but aren’t sure a four-year nursing degree or medical school is the right fit, cardiac sonography might be the career you haven’t heard enough about. Lackawanna College, a regionally accredited, non-profit institution serving Northeast Pennsylvania since 1894, offers a two-year Associate in Science in Cardiac Sonography at its Scranton main campus — a program built around the same ARDMS-aligned curriculum and clinical training that hospitals across the region expect from new hires. This guide walks through what cardiac sonographers actually do, what the career looks like day to day, what it pays, and how you can train for it right here in Pennsylvania.
What Does a Cardiac Sonographer Do?
A cardiac sonographer — sometimes called an echocardiographer or cardiac ultrasound technologist — uses high-frequency sound waves to capture detailed images of the heart. The images they produce, called echocardiograms, show cardiologists how well the heart is pumping, whether the valves are working correctly, and whether there are any structural abnormalities that need treatment. The role is hands-on, patient-facing, and directly involved in one of the most critical areas of medicine: cardiovascular care.
On any given shift, a cardiac sonographer prepares patients for their echocardiogram, explains the procedure, operates the ultrasound equipment to capture clean images of the heart’s chambers and vessels, recognizes the difference between a normal and abnormal image in real time, and documents findings for the physician. They also frequently assist cardiologists during procedures like stress echocardiograms. Because heart disease is one of the most common reasons people seek medical care, cardiac sonographers are in demand across hospitals, primary clinics, cardiology practices, diagnostic imaging centers, and traveling contract positions — giving graduates real flexibility in where and how they build a career.
Salary, Outlook, and Why This Career Is Growing
Salaries in cardiac sonography vary by experience, specialization, and employer type. According to the U.S. Bureau of Labor Statistics, diagnostic medical sonographers — the career category that includes cardiac sonographers — earn a wide range depending on market and tenure, with experienced sonographers in large hospital systems and traveling contract roles earning toward the top of that range. Entry-level graduates typically start lower and grow quickly as they specialize and gain clinical hours.
What makes this career especially attractive is the return on investment. The Bureau of Labor Statistics projects 14% growth for diagnostic medical sonographers between 2020 and 2030, much faster than the average for all occupations. As the U.S. population ages and cardiovascular care demand continues to rise, hospitals and clinics consistently report a need for credentialed cardiac sonographers they can hire directly out of accredited programs. A two-year associate degree can take you from high school to a full-time healthcare career with benefits in the same amount of time many of your peers are still halfway through a bachelor’s degree — with comparable or higher lifetime earnings in many cases.
Key Takeaway: Cardiac sonography is one of the fastest-growing allied health careers in the country, and because qualified graduates can enter the workforce with a two-year accredited associate degree, the cost-to-earning ratio is significantly more favorable than most four-year healthcare tracks.
How to Become a Cardiac Sonographer in Pennsylvania
The path from high school to working cardiac sonographer is shorter than most people realize. The process starts with earning a high school diploma or GED, then applying to an accredited cardiac sonography program. Accreditation matters at this step — without it, graduates may not be eligible to sit for the American Registry of Diagnostic Medical Sonographers (ARDMS) credentialing exams, and most hospitals will not hire a sonographer who is not registry-eligible.
Once enrolled, students complete a two-year, four-semester curriculum that blends general education with specialized cardiac coursework. The cardiac sonography curriculum at Lackawanna College includes Medical Terminology, Anatomy and Physiology, Introduction to Ultrasound Physics, Cardio Pathophysiology, Cardiovascular Anatomy and Physiology, Cardiac Clinical rotations, and Introduction to Vascular Sonography. Classes are taught during the day, evenings, and on Saturdays, and every student completes on- and off-campus clinical hours at regional hospital-based and freestanding ultrasound laboratories so they graduate with real scanning experience, not just classroom instruction.
The final step is the registry exam itself. Students in accredited programs are eligible to sit for the ARDMS examinations 60 days before graduation, which gives them a significant credentialing edge when they enter the job market. Most cardiac sonographers pursue the Registered Diagnostic Cardiac Sonographer (RDCS) credential, which many hospitals require or strongly prefer at the time of hire.
The Cardiac Sonography Program at Lackawanna College
Lackawanna College offers the Associate in Science in Cardiac Sonography at its Scranton main campus, housed within the Division of Health Sciences. It is one of three sonography specializations students can pursue alongside Vascular Sonography and Diagnostic Medical Sonography. Because admissions are selective, Lackawanna limits the cardiac sonography cohort to a maximum of 30 students per year, which translates to smaller class sizes, more one-on-one time with faculty, and more hands-on scanning practice than students typically get in larger university programs.
The Scranton campus also operates a dedicated sonography lab where students train on the same type of equipment they will use in the clinical setting. Lackawanna’s sonography programs are accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) upon the recommendation of the Joint Review Committee on Education in Diagnostic Medical Sonography (JRC-DMS), which is what makes graduates eligible for the ARDMS exams.

Choosing a career in the medical field is one of the best choices a person can make.
Medical careers are highly sought after, and if you’re considering a career in ultrasound, choose one of the sonography programs at Lackawanna College.
Lackawanna College’s sonography programs are accredited through CAAHEP — the Commission on Accreditation of Allied Health Education Programs. Being in an accredited program, students will take their registry exams 60 days prior to graduation, making them more marketable.
Lackawanna College’s sonography department offers an associate’s degree in one of three specializations, including diagnostic medical sonography, cardiac sonography, and vascular sonography.
These programs are among the Division of Health Sciences, where superior education fosters the finest patient care.
Although the three specializations have similarities, there are key differences between each program. By offering students a more tailored curriculum, they’ll be well-prepared for the specific demands of their career path in sonography.
Each program is designed to be completed over a two-year period with day, evening, and Saturday courses that are taught at the main campus located in Scranton, Pennsylvania. There is also a dedicated sonography lab where students will learn the hands-on training needed to excel in the field of sonography.
Students will be provided with over 900 clinical internship hours with one of our multiple affiliates — including hospital-based, outpatient, and private-practice labs.
“I relocated from out of state to Pennsylvania to attend the sonography program at Lackawanna College because when I was looking for a sonography program with the accreditations that I wanted, Lackawanna College pulled up under the top 20 across the nation. So that’s why I chose to relocate to this program.”
“After determining that a career in sonography was best for me, I researched the top ultrasound schools in Pennsylvania. Lackawanna was top in ratings and numbers, and with dorming available, Lackawanna College was my number one choice.”
Lackawanna College provides housing in Seeley Hall — the same building where all classes are held — making getting from place to place very convenient. Whether you’re right out of high school or a non-traditional student, the sonography programs will give you the education you need to succeed.
With our current statistics, we have a greater than 95% rate for board passing and employment. You can also earn multiple specialties, as I did — earning my vascular technology credential and returning for a dual degree in cardiac sonography. You may even have opportunities in education. I’m a graduate of both the cardiac and abdominal sonography programs; I earned my credentials in all three modalities, and I’m currently an adjunct instructor and lab assistant for Lackawanna College.
Graduates of the program can expect to earn a base salary of $65,000 per year. Considering the low-cost tuition offered at Lackawanna College in a two-year degree program, it’s a win-win situation.
Before students enter the lab, they put on their personal protective gear to keep each other safe and to practice proper technique. To give you a more detailed look at our different modalities, I’d like to introduce you to our patient, Mrs. Smith. Mrs. Smith has to meet with each department, per the physician’s order, to rule out the source of her recent stroke and her high blood pressure.
As a vascular technologist, we may receive a doctor’s order to evaluate the cause behind Mrs. Smith’s stroke. Vascular technologists specialize in imaging and evaluating the blood flow of the veins and arteries throughout the body to help diagnose pathologies — some of which can be life-threatening. As it turns out, Mrs. Smith’s carotid ultrasound was not the source of her recent stroke, so she’s referred to the echo lab to check whether any pathology within the heart may have caused it.
Echo technologists specialize in imaging the heart chambers, valves, and heart muscle, along with analyzing the hemodynamics — the blood flow — through the heart, to diagnose different cardiac pathologies. Mrs. Smith had diagnostic exams in both the cardiac and vascular labs; however, the source of the stroke still hasn’t been determined. She’ll now go to the diagnostic lab for further evaluation of her kidneys and renal arteries.
Through the images obtained in Mrs. Smith’s diagnostic scan, it’s determined that her high blood pressure is a result of renal failure — the images show severe hydronephrosis, a backup of urine in the kidneys. It’s also determined that the renal failure may have contributed to her high blood pressure and her stroke. Diagnostic medical sonographers specialize in many sub-specialties, including abdominal, OB/GYN, and small parts — thyroid, breast, testicular, and musculoskeletal imaging.
Although ultrasound is our common link, you can see each specialty is quite different. Choose a degree in sonography. Choose Lackawanna College.
