费城儿童医院用开源 NVIDIA AI 秒级建模儿童心脏
原标题：Heart of the Matter: How a Major Children’s Hospital Uses Open Source NVIDIA AI for Cardiac Care
AI 摘要
费城儿童医院（CHOP）利用基于 MONAI 的开源 AI 工具，将儿童心脏建模从过去需数小时的人工操作缩短至数秒，用于先天性心脏病的术前规划。该服务已推广至美国 20 多家儿童医院，波士顿儿童医院每年约 500 例心脏手术借助建模完成。CHOP 还与 NVIDIA 合作，基于 Warp 和 Newton 物理引擎开发 GPU 加速的生物力学仿真，目标是将心脏器械模拟从数小时降至近实时，并计划通过 OpenUSD 和 Omniverse 数字孪生将仿真引入临床工作流。

Children’s Hospital of Philadelphia is using open source AI tools to model children’s hearts in seconds — with the goal of enabling safer, more precise care for kids with congenital heart disease. About 1% of all live births involve a congenital heart defect — and no two are alike. A child born with a hole between the lower chambers of their heart, or a leaking valve in the single pumping chamber keeping them alive, needs care that fits their exact anatomy. Historically, the devices surgeons rea
