Frequent Questions About 3D, 4D & HD Ultrasound


What is an elective prenatal ultrasound?
We offer elective 2D, 3D & 4D prenatal ultrasounds to provide a proactive, positive bonding experience for the mother, father and family members with the unborn baby. Realistic surface images provide a connection between the parents and baby that can be beneficial to the whole family. A medical, diagnostic ultrasound should have already been performed to assess the gestational age of the fetus and to evaluate for fetal anomalies, as well as the basic components of fetal anatomy.
Does this take the place of an ultrasound at my doctor’s office?
ABSOLUTELY NOT! Women seeking an elective prenatal ultrasound with Jelly on my Belly 3D & 4D Ultrasound must already be receiving treatment with a healthcare provider for prenatal care and have already undergone a medical, diagnostic ultrasound ordered by their provider to confirm their due date, screen for fetal anomalies, and to look for any other pregnancy related issues. Your imaging session at Jelly on my Belly 3D & 4D Ultrasound is strictly an elective ultrasound. We demonstrate and document only the existence of a heart beat. Please note, at no time is this elective experience to be confused with, or used in place of, a diagnostic ultrasound.
Is it safe? Are there any risks to me, or my baby?
Extensive studies conducted over 35 years have found that ultrasound has not been shown to cause any harm to mother or baby. Routine scanning of all pregnancies is now normal throughout the United States. These routine scans would be considered highly irresponsible if there were even a small risk to mother or baby. In 3D/4D scanning, exactly the same type and intensity of ultrasound is used as with conventional 2D scanning. 3D and 4D Ultrasound both utilize sound waves to look inside the body. The technology is similar to radar. A probe placed on the body emits sound waves into the body, listens for the return echo and generates an image. 4D ultrasound will be similar to a conventional scan in terms of sound exposure.
About Us
Barbara and Tom Costas, a husband and wife team, founded Jelly on my Belly. They met in 1997 while attending the Diagnostic Medical Sonography program at STCC. Both graduated with an Associate Degrees in Medical Sonography in 1999.
Barbara has spent majority of her career performing ultrasounds in obstetrics and gynecology. She started in a high risk maternal fetal medicine department at Hartford Hospital. After many years in the hospital setting, she transitioned to a local Ob/Gyn practice. Barbara is highly regarded by her peers for her extensive experience and knowledge.
Tom began working at a small hospital that performed various types of ultrasounds. He then partnered with a local surgeon to open a vascular lab to support his practice. A few years later, he had the opportunity to manage a diagnostic imaging center for a large physician’s practice. This was when the idea of opening a 3D ultrasound studio became more than just a thought.


Barbara and Tom dedicated over a year of planning and research before launching Jelly on my Belly in 2018. Their goal wasn’t just to open a 3D ultrasound studio. It was to create the studio that families trusted and turned to for the special experience of seeing their baby. Their expertise and professionalism quickly earned the trust of both the community and local healthcare Providers.
The success of our East Longmeadow, Massachusetts studio inspired us to expand and bring our services to more families. In August 2024, we proudly opened our second studio in Arlington, Massachusetts. We are thrilled to offer the Boston area the same exceptional 3D ultrasound experience that has made Jelly on my Belly a trusted name in elective prenatal imaging. Our goal is to create unforgettable moments for growing families, one heartbeat at a time.
