FDA-cleared profile
Nexsys Electronics Inc. dba Medweb
Lightning Viewer is software for diagnostic and clinical review of general-radiology and other healthcare imaging applications. The FDA indication describes review and navigation of diagnostic images with tools for visualization, and use with appropriate displays by trained healthcare professionals.
Clinical fit
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Regulatory identity
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Implementation
Use these fields to structure a vendor demo, security review, and implementation estimate.
The exact FDA material describes this input or interface boundary; local interoperability acceptance remains necessary.
The exact FDA material describes this release-level deployment boundary; hosting, contracts, security, availability, and site configuration remain separate evidence.
Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.
Map installed model, build, options, population, anatomy, inputs, outputs, and enabled functions to K242362 before acceptance. Later family features are not evidence for this exact submission.

Test representative identifiers, geometry, measurements, units, routing, failure handling, and round trips locally.
exact submission · checked 2026-09-04The FDA summary describes a web-based viewer that is part of a server and uses off-the-shelf computing devices; exact hosting, availability, security, browser support, and responsibility remain unverified. Security, availability, retention, and service responsibilities remain unverified.
exact submission · checked 2026-09-04Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. The FDA material states that display monitors, lighting, image quality, compression, and calibration must be appropriate for the clinical purpose and that lossy compression is not for primary mammography reading. It does not establish a universal diagnostic-performance claim.

Evidence
Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.
Sensitivity is not a product-wide endpoint for this system or software function. Compare only an exact endpoint, threshold, population, version, and source if later verified.
Specificity is not a product-wide endpoint for this system or software function. Compare only an exact endpoint, threshold, population, version, and source if later verified.
No contextualized exact-version metric has completed evidence review. Regulatory-document values, when available, are shown above with their limitations.

The FDA decision material is manufacturer-submitted regulatory evidence. It is not independent clinical validation, and local technical, clinical, privacy, security, and workflow acceptance remains necessary.
Economics and lifecycle
These are common procurement questions; unknown values remain visible until a source supports them.
No public list price for the exact cleared or approved configuration was found. Obtain a written quote separating hardware or license basis, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.
No separate named-product payment identified in reviewed public material

Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Exact-identifier review does not prove absence of all product-family safety signals.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact-name and exact-submission searches in the checked indexes returned no PubMed records and no ClinicalTrials.gov records for K242362; no published exact-submission recall was promoted. Candidate literature, registry, and non-native recall records remain quarantined unless exact product, version, and submission linkage is established. The FDA decision material remains the identity and intended-use anchor for Lightning Viewer. Pricing, complete security architecture, contracted deployment, exact reimbursement, and local interoperability remain unverified. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.
Candidate leads remain unpublished until a human confirms the exact product and tested version.
