CHOP Cuts Pediatric Heart 3D Modeling from 4 Hours to Seconds with Open-Source MONAI

Children's Hospital of Philadelphia (CHOP) built a cardiac modeling service on MONAI, an open-source medical imaging framework co-founded by NVIDIA: it uses pediatric patients' existing CT, MRI and 3D ultrasound scans to generate anatomically precise, patient-specific 3D heart models in seconds, work that previously took a skilled researcher about 4 hours by hand. The models are already used in cath labs and for pre-surgical "customized" device fitting. Multiple posters cited it as a landmark case of AI deployment in pediatric clinical care.

Confirmed

CHOP built the cardiac modeling platform on the NVIDIA MONAI open-source toolchain, converting CT, MRI and 3D ultrasound images into detailed patient-specific 3D heart models
Modeling time dropped from 4 hours of manual work to seconds; the time figures are attributed to Dr. Jolley
The models let physicians study each child's individual cardiac anatomy pre-operatively and are used in cath labs and pre-surgical device fitting assessments

Why it matters

Physicians can study each child's individual heart structure before surgery, aiding surgical planning — especially significant for complex congenital heart disease (DeryaTR noted CHD affects a notable share of newborns)
The entire pipeline is built on an open-source framework, so other hospitals can replicate it rather than rely on a closed commercial product
It demonstrates AI moving from research into real clinical workflows: second-level modeling from existing scans, with no additional imaging required
