The summary describes image processing and analysis software for brain images (CT and MRI) focused on perfusion and diffusion parameters. It details data acquisition, processing steps (volumetry, time intensity plots, mismatch measurement), and system architecture. There is no mention of AI, ML, deep learning, or any related terms in the provided text. The performance studies described are focused on accuracy of parameter representation and software validation, not on the performance metrics typically associated with AI/ML models (like AUC, sensitivity, specificity from a classification or detection task).
No
The device is described as image processing software used for viewing, processing, and analysis of brain images. It does not provide therapy or treatment for a disease or condition.
Yes
The device is an "image processing software package" that performs "processing and analysis of brain images" for "trained professionals, including but not limited to physicians and medical technicians" to provide "visualization and study of changes of tissue perfusion and diffusion." This functional description indicates that it aids in diagnosis by processing medical images and providing actionable information for medical professionals.
Yes
The device description explicitly states, "RAPID is a software-only device consisting of one or more RAPID Servers (dedicated or virtual and an iSchemaView Server)." While it interacts with hardware (standard computers, virtual platforms, DICOM devices), the device itself, as described, is the software package.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples: In Vitro Diagnostics are designed to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- RAPID analyzes medical images: RAPID processes and analyzes medical images (CT and MRI scans) of the brain. It does not interact with or analyze biological samples.
Therefore, RAPID falls under the category of medical imaging software or a medical device that processes imaging data, not an In Vitro Diagnostic.

-
measurement of mismatch between labeled volumes on co-registered image volumes
RAPID is a software-only device consisting of one or more RAPID Servers (dedicated or virtual and an iSchemaView Server). The RAPID Server is an image processing engine that connects to a hospital LAN, inside the Hospital Firewall. It can be a dedicated RAPID Server or a vmRAPID appliance, which is a virtualized RAPID Server that runs on a dedicated hospital server. Where available, the RAPID Server is placed logically in the demilitarized zone (DMZ) of the hospital's network to facilitate bidirectional secure connection between the (local) RAPID Server and the centralized iSchemaView Server.
The RAPID Server is configured to connect to applicable DICOM devices (PACS, Imaging Modalities, Research Workstations) via the hospital LAN and to receive diffusion and perfusion (DICOM) data directly and automatically from imaging modalities as they become available. It processes acquired data and delivers postprocessed images directly back to imaging modalities, local PACS and/or workstations, again using DICOM communication. It also transmits data to the iSchemaView Server for storage, retrieval and viewing.
The iSchemaView Server is a dedicated server that provides a central repository for RAPID data. All iSchemaView Server data is stored on encrypted hard disks. It also provides a user interface for accessing RAPID data. It connects to a firewalled Data Center Network and has its own firewall for additional data security.

Technological Characteristics
RAPID performs the following functions:
- processes DICOM images from multiple sources to provide visualization of changes of . tissue perfusion and diffusion
- receives DICOM images from external DICOM image providers (modalities (CT/MRI . Scanners), PACS and Workstations) and sends DICOM images to external image consumers
- processes requests, statuses and results, and references therein, which are stored in a . queryable database
- processing status is available through a web browser using HTTP, HTML and PHP. .
- can send summary results to the user over email. For this, RAPID generally connects to the . infrastructure of the medical partner (e.g., the hospital). In particular, RAPID uses a SMTP protocol with security extensions to provide secure emailing.
RAPID is available in the following configurations:
- Standard RAPID, which is installed directly on a customer's Linux-based PC and integrated . with medical image processing software such as commercial PACS.
- . Virtual RAPID, wherein the user accesses RAPID online and uses it to process DICOM images otherwise available on his/her computer.
RAPID is a DICOM-compliant PACS software that provides comprehensive functionality to transfer, process, and display diffusion-weighted MRI (DWI) and dynamically acquired CT and MR imaging data (following the administration of a bolus of contrast media). RAPID runs on standard "off-theshelf" computer and networking hardware. RAPID is entirely independent from CT, MRI, or PACS platforms. It supports secure VPN (Virtual Private Network) networking or encapsulated Secure Shell (SSH), and seamlessly integrates into an existing radiological data network.
The primary users of RAPID PACS software are medical imaging professionals who analyze diffusion MRI and/or dynamic CT or MRI images. The images generated by RAPID provide additional diagnostic information, which is derived from the temporal/diffusion features of the native CT or MRI images.
Performance Data
RAPID complies with DICOM (Digital Imaging and Communications in Medicine) - Developed by the American College of Radiology and the National Electrical Manufacturers Association. NEMA PS 3.1 - 3.20 (2011).
Additionally. iSchemaView conducted extensive performance validation testing and software verification and validation testing of the RAPID system. This performance validation testing demonstrated that the RAPID system provides accurate representation of key diffusion and perfusion processing parameters under a range of clinically relevant parameters and perturbations associated with the intended use of the software. Software validation and verification testing demonstrated that the RAPID system met all design requirements and specifications.

Substantial Equivalence
RAPID is as safe and effective as the Olea Sphere. RAPID has the same intended use and similar indications, technological characteristics and principles of operation as its predicate device. The minor technological differences between the RAPID and its predicate raise no new issues of safety or effectiveness as demonstrated by the testing conducted with RAPID that confirms that the software reliably processes CT diffusion and MRI diffusion and perfusion medical images. Thus, the RAPID software is substantially equivalent.
