### Device Description
RAPID is a software package that provides for the visualization and study of changes of tissue perfusion and diffusion in digital images captured by CT (Computed Tomography) and MRI (Magnetic Image Resonance). RAPID can be installed on a customer PC or it can be accessed online as virtual system. It provides viewing, quantification, analysis and reporting capabilities.
RAPID works with the following types of (DICOM compliant) medical image data:
- · CT (Computed Tomography)
- · MRI (Magnetic Image Resonance)
RAPID acquires (DICOM compliant) medical image data from the following sources:
- · DICOM file
- · DICOM CD-R
- · Network using DICOM protocol
{1}------------------------------------------------
RAPID provides tools for performing the following types of analysis:
- · volumetry of threshold maps
- · time intensity plots for dynamic time courses
- 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. The iSchemaView Server connects to one or more RAPID Servers via WAN. Available types of connection include VPN (Virtual Private Network - RFC2401 and RFC4301 Standards) Tunnel and SSH (Secure Shell).
## Intended Use / Indications for Use
iSchemaView's RAPID is an image processing software package to be used by trained professionals, including but not limited to physicians and medical technicians. The software runs on a standard "off-the-shelf" computer or a virtual platform, such as VMware, and can be used to perform image viewing, processing and analysis of brain images. Data and images are acquired through DICOM compliant imaging devices.
iSchemaView's RAPID provides both viewing and analysis capabilities for functional and dynamic imaging datasets acquired with CT Perfusion and MRI including a Diffusion Weighted MRI (DWI) Module and a Dynamic Analysis Module (dynamic contrast enhanced imaging data for MRI and CT).
The DWI Module is used to visualize local water diffusion properties from the analysis of diffusionweighted MRI data.
The Dynamic Analysis Module is used for visualization and analysis of dynamic imaging data. showing properties of changes in contrast over time. This functionality includes calculation of parameters related to tissue flow (perfusion) and tissue blood volume.
{2}------------------------------------------------
## 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.
{3}------------------------------------------------
## 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.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
