AI Rad Companion (Engine)

The AI-Rad Companion (Engine) is a software platform designed to assist technicians and trained physicians by providing visualization, storage, and transfer capabilities for medical images, supporting qualitative and quantitative analysis of clinical data for diagnostic purposes. It operates through a DICOM-compatible interface for multi-modality data, integrates external post-processing extensions including those using artificial intelligence, features user interfaces for confirmation and configuration, and is deployable on Siemens' cloud infrastructure with updates enhancing access to extensions and workflow visualization.

The AI-Rad Companion (Engine) is a software platform developed by Siemens Medical Solutions USA, Inc., designed for basic visualization and to enable external post-processing extensions for medical images used in diagnostic procedures. Its primary purpose is to support technicians and trained physicians in the qualitative and quantitative measurement and analysis of clinical data. The platform facilitates the storage of data and its transfer to other systems, such as PACS, and provides an interface for integrating various processing extensions. Key functionalities include a multi-modality and multi-vendor DICOM data interface, data validity checks using DICOM tags, an interface for post-processing extensions, and user interfaces for visualizing processed images and configuring the device and its extensions. Updates to the device include a modified indications for use statement and support for software version VA10A, which enables deployment on Siemens cloud infrastructure, an improved method for accessing and configuring optional post-processing extensions, and a modified workflow for visualizing and confirming their output. Performance of the AI-Rad Companion (Engine) was established through non-clinical testing, including software validations and bench testing encompassing unit, subsystem, and system integration tests. These tests confirmed the device's functionality and compliance with several industry standards, such as DICOM (NEMA PS 3.1-3.20), IEC 62304 for medical device software life cycle processes, ISO 14971 for risk management, and IEC 62366-1 for usability engineering. A risk analysis was completed, and mitigation measures were implemented. Cybersecurity considerations are addressed through processes to prevent unauthorized access and misuse of information, aligning with IEC 80001-1. Human factor usability validation was also conducted, ensuring the system is suitable for trained users in clinical environments. The testing confirmed that all software specifications met acceptance criteria, supporting its intended use for enhancing clinical data analysis.
