Sabarish Sathasivan
Software Architect at American College of Radiology
Actions
I am a Cloud Architect with 20+ years of engineering experience, specializing in serverless, data‑intensive, and GenAI platforms on AWS. I build secure, scalable architectures for regulated environments such as Healthcare and Life Sciences.
I’m also a 3× AWS DMV Community Day speaker and an AWS Community Builder (Serverless).
Area of Expertise
Serverless Agentic Analytics in Radiology
1) How we built a custom data analytics chatbot for our Data Science team that can query and visualize data from Athena, MySQL, and Redshift using a serverless stack with Lambda, ECS Fargate, API Gateway WebSockets, and Bedrock AgentCore.
2) How we migrated a number of Tableau reports to a serverless reporting tool using Lambda, Redshift, the Data API, and Kiro.
3)How agentic AI development using Kiro is helping to drive innovation in ACR.
Building Agentic AI Workflows using AgentCore: From Data Chatbots to DICOM Automation
This session demonstrates how agentic AI architectures built on AWS—using Amazon Bedrock Agent Core, Lambda, and a serverless integration layer—can automate and streamline radiology and imaging workflows.
1) Deep dive of a conversational analytics assistant that connects to MySQL, Athena, and Amazon S3, generates text‑to‑SQL, produces plots/tables/narratives, and executes Python code for data analysis.
2) Deep dive into an agentic imaging assistant that interacts with VNA systems to retrieve and route DICOM studies, reducing manual steps in radiology workflows.
How AI / ML Services in AWS is driving innovations in ACR
I want to present 3 use cases where we use AI/ML Services in ACR
1) De-identify medical images using Amazon Comprehend Medical and Amazon Rekognition
2) Performing algorithm performance monitoring in clinical practice using Amazon Bedrock
3) Implementing Intelligent Search using Bedrock Data Automation, knowledge Bases and Bedrock
