Artificial Intelligence in Healthcare & Medicine
Artificial Intelligence (AI) has been making significant strides in revolutionizing healthcare, and open source initiatives are playing a crucial role in accelerating progress. In this article, we will delve into three notable open source AI efforts: MONAI, HeartKit, and VinDr Lab. Each project brings a unique approach to the application of AI in healthcare, fostering collaboration and advancing the field.
Project MONAI: Driving Collaboration in Healthcare Imaging
One prominent open source AI effort in healthcare is Project MONAI, an inclusive community formed by NVIDIA and King’s College London. Its primary aim is to establish best practices for AI in healthcare imaging across academia and enterprise researchers. Since its inception, Project MONAI has expanded to include industry leaders and researchers in medical imaging.
MONAI offers a suite of open-source PyTorch-based frameworks that cover the entire medical AI life cycle. The MONAI Core provides a domain-specific framework for training AI models in healthcare imaging, ensuring reproducibility and easy integration. Researchers can leverage MONAI Label, an intelligent image labeling tool, to annotate new datasets efficiently. The MONAI Deploy App SDK allows developers to convert AI models into applications seamlessly. Lastly, the MONAI Model Zoo offers a collection of pre-trained medical imaging models.
HeartKit: Empowering Real-Time Heart Monitoring
HeartKit, an initiative by Ambiq.ai, focuses on enabling real-time heart-monitoring applications on battery-powered edge devices. HeartKit employs an optimized open-source TinyML model designed for efficiency, explainability, and extensibility.
The architecture of HeartKit comprises an ECG segmentation model and three upstream heads: HRV head, arrhythmia head, and beat head. The ECG segmentation model annotates each sample as P-wave, QRS, T-wave, or none. The arrhythmia head detects the presence of Atrial Fibrillation (AFIB) or Atrial Flutter (AFL). The HRV head calculates heart rate, rhythm, and heart rate variability, while the beat head identifies irregular beats.
With HeartKit, healthcare professionals can leverage edge devices to perform real-time heart monitoring, providing timely insights and improving patient care.
VinDr Lab: Building High-Quality Medical AI Algorithms
VinDr Lab, developed by the Medical Imaging team at Vingroup Big Data Institute (VinBigdata), offers a powerful data platform for medical AI. It enables the creation of high-quality datasets and algorithms with advanced annotation features and a streamlined process.
VinDr Lab provides a comprehensive set of features for managing medical data, tracking project progress, and creating and sharing label groups. It offers annotation tools such as bounding boxes, polygons, brushes, and notes, facilitating precise and detailed annotations. The platform also allows for version control of exported labels, ensuring reproducibility and traceability.
VinDr Lab empowers researchers and developers to build robust and accurate medical AI algorithms, fueling advancements in diagnosis, treatment, and research.
The Power of Open Source in Healthcare
The advent of open source AI efforts in healthcare brings numerous opportunities for collaboration, knowledge sharing, and innovation. By embracing open source frameworks like MONAI, HeartKit, and VinDr Lab, researchers and developers can leverage established best practices, high-quality software, and community support to accelerate their AI projects.
These initiatives foster an environment of collaboration, enabling researchers from academia and industry to work together, share results, and build upon each other’s work. Open source AI efforts also enhance reproducibility, transparency, and accessibility, contributing to the democratization of healthcare AI.
As open source projects continue to evolve, the healthcare community can leverage these advancements to address complex challenges, improve patient outcomes, and pave the way for a future where AI plays an integral role in healthcare delivery.
