Digital Event Horizon
The world of medicine is witnessing a paradigm shift, thanks to the advent of open source AI tools that are revolutionizing the way children's hospitals approach cardiac care. This article delves into the story of Children's Hospital of Philadelphia's cardiac modeling service, built on NVIDIA's open source medical imaging framework MONAI, and its impact on cardiac care.
Children's Hospital of Philadelphia (CHOP) is harnessing open source medical imaging framework MONAI to model children's hearts with unprecedented precision. MONAI's cardiac modeling service reduces the time required for cardiac modeling from four hours to routine clinical use. CHOP's cardiac modeling service is part of a larger ecosystem of open source tools being developed to support cardiac care. The collaboration between CHOP and NVIDIA has developed tools such as MONAI, Newton, and OpenUSD to simulate cardiac device deployment and predict disease progression. Open source AI tools have reduced the time required for cardiac device simulation from up to four hours to just a few minutes. More than 20 children's hospitals across the U.S. are now running cardiac modeling programs. The use of open source tools has enabled researchers to collaborate across institutions, sharing data and tools to advance the field of cardiac care.
The world of medicine is witnessing a paradigm shift, thanks to the advent of open source AI tools that are revolutionizing the way children's hospitals approach cardiac care. At the forefront of this innovation is Children's Hospital of Philadelphia (CHOP), which has been harnessing the power of open source medical imaging framework MONAI, in collaboration with NVIDIA, to model children's hearts with unprecedented precision.
According to Dr. Matthew Jolley, a cardiologist and researcher at CHOP, "You've got a one-of-a-kind kid and an off-the-shelf device. Our job is to find what fits — and modeling lets us do that before anyone goes into the cath lab or operating room." The hospital's cardiac modeling service, built on MONAI, takes images a child's care team already has, such as CT scans, MRI, and 3D ultrasound, and produces anatomically precise heart models in just seconds. This approach has significantly reduced the time required for cardiac modeling, from four hours of work by a skilled researcher to routine clinical use.
CHOP's cardiac modeling service is not just a one-off innovation; it's part of a larger ecosystem of open source tools that are being developed to support cardiac care. The hospital is also working on the IDEA Lab, a research initiative aimed at applying the same tools across multiple disciplines. This approach has the potential to transform the way cardiac care is delivered, making it more personalized and effective.
The use of open source AI tools in cardiac care is not a new phenomenon. Researchers at Stanford and Boston Children's have been contributing additional tools to SlicerHeart, an open source software for visualizing, segmenting, and analyzing 3D medical images. However, it's the collaboration between CHOP and NVIDIA that has taken the field by storm. The two entities have developed a range of tools, including MONAI, Newton, and OpenUSD, that are being used to simulate cardiac device deployment and predict disease progression.
Newton, an open source physics engine built on NVIDIA Warp, is being used to run physics simulations on GPUs. This has enabled clinicians to understand tissue material properties that determine how a device will deploy in a given patient. With GPU acceleration, simulations can now be completed in near real-time, reducing the time required for cardiac device simulation from up to four hours to just a few minutes.
CHOP has begun implementing features built on NVIDIA Warp and Newton to understand how a device will work in a patient's heart. This has significant implications for the way cardiac care is delivered, enabling clinicians to make more informed decisions about device deployment and surgical planning.
The impact of open source AI tools on cardiac care is not limited to CHOP. More than 20 children's hospitals across the U.S. are now running cardiac modeling programs, with Boston Children's Hospital using modeling to support more than half of all cardiac surgeries. The use of open source tools has also enabled researchers to collaborate across institutions, sharing data and tools to advance the field of cardiac care.
The story of CHOP's cardiac modeling service is one of collaboration and innovation. The hospital's researchers worked with the open source community to build SlicerHeart, an extension of 3D Slicer open source software for visualizing, segmenting, and analyzing 3D medical images. The team trained segmentation networks on pairs of prior images and models, producing output that meets the same quality standard as a trained human would produce — in seconds rather than hours.
The use of open source AI tools in cardiac care is also being driven by economic considerations. According to Dr. Jolley, "It's too small a population to support traditional commercial development by normal economics." The use of open source tools has enabled researchers to collaborate and progress without barriers, making it possible to develop tools that would otherwise be too expensive or complex to build.
In conclusion, the use of open source AI tools in cardiac care is revolutionizing the way children's hospitals approach cardiac care. The collaboration between CHOP and NVIDIA has resulted in the development of a range of tools that are being used to simulate cardiac device deployment and predict disease progression. As the field continues to evolve, it's likely that we'll see even more innovations in the years to come.
