Rapid CTA 360

iSchemaView

Rapid CTA 360 analyzes adult head CTA DICOM images to flag suspected large- and medium-vessel occlusion in specified intracranial and vertebral segments and notify trained clinicians for workflow triage; notifications are informational and not diagnostic.

Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

Clinical details

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose
Rapid CTA 360 analyzes adult head CTA DICOM images to flag suspected large- and medium-vessel occlusion in specified intracranial and vertebral segments and notify trained clinicians for workflow triage; notifications are informational and not diagnostic.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Intended users
Trained clinicians and stroke teams who review head CTA triage notifications and the source examination; a notification does not replace professional judgment or diagnosis.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Care setting and population
Emergency, stroke, radiology, or neurovascular workflow in which adult head CTA is acquired and urgent triage notification is needed.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Workflow role
Parallel radiological triage and notification to surface suspected vessel occlusion for clinician attention; it does not alter the original study or provide a diagnosis.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Required input
Adult head CTA DICOM examinations covering the specified intracranial and vertebral vessel segments.
  • FDA source

Output and human action
Suspected occlusion triage notifications, reports, and DICOM Secondary Capture or compressed preview content for clinician workflow; the original CT study is not changed.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Limitations
The software is for triage and notification, not diagnosis or primary image interpretation. Notifications are informational, can be delayed or absent, and require review of the original CTA by qualified clinicians. The validated sensitivity and specificity apply to the FDA-described adult datasets and vessel definitions.

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
The exact system receives adult head CTA DICOM studies, processes them in parallel with standard reading, and sends notifications and DICOM Secondary Capture or preview outputs; local PACS/RIS routing, notification channels, downtime, and escalation require acceptance testing.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Deployment and data flow
The FDA packet describes server or standalone desktop deployment with workflow notifications; the reviewed exact materials do not establish current hosting topology, service availability, retention, or infrastructure terms for a particular installation.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Security and privacy
The FDA packet describes an OWASP risk process, annual ISO 27001/27701 certification, and UL-2900-1 conformance as part of the reviewed security evidence; current certificate scope, expiry, deployed configuration, and operational controls require confirmation.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07

This records the exact FDA packet's described evidence and is not a current independent security attestation.

Training and support
Trained clinicians must review notifications against the original CTA and understand that the output is triage-only; local onboarding should cover covered vessel segments, notification failure and delay, escalation, and downtime procedures.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07
Monitoring and change control
Monitor CTA eligibility, notification latency and delivery, false-positive and false-negative review, original-study review completion, DICOM routing, downtime and escalation, software updates, complaints, and recalls by exact K251151 release.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-07

Buyer acceptance guidance derived from the exact FDA workflow and validation scope; it is not a claimed vendor monitoring service.

Parallel CTA triage workflow

The exact submission processes head CTA in parallel with standard reading and sends workflow notifications while leaving the original study unchanged; test notification latency, delivery, escalation, and downtime locally.

Rapid CTA family stroke workflow

RapidAI describes Rapid CTA as automatically processing CTA to assess reduced blood flow, identify and locate suspected large- or distal-vessel occlusion, and notify stroke teams for transfer decisions.

product family · checked 2026-09-07

Current family workflow page; it does not establish every feature, vessel scope, or deployment term for the K251151 release.

DICOM notification and preview outputs

The FDA packet describes DICOM Secondary Capture and compressed preview or notification outputs; establish local PACS storage, mobile/web or other notification channels, retention, and clinician acknowledgement procedures.
