Imbio RV/LV Software

Imbio, LLC

Authorized purpose: Measures maximal right- and left-ventricular diameters and reports their ratio.

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

Product overview

Start with the essentials

Authorized purpose: Measures maximal right- and left-ventricular diameters and reports their ratio.

Overview status: Source-reviewed overview

Clinical takeaway

Clinical role: Measures maximal right- and left-ventricular diameters and reports their ratio.

Evidence takeaway

Evidence from the reviewed source record: Software validation and two reader-study evaluations using anonymized CTPA datasets; the reviewed packet gives no sample size, numeric endpoint, or reference standard.

Implementation

Questions for IT, informatics, and operations

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

Integration
The exact-submission ACR model card explicitly references DICOM in the described input, output, or workflow; exact interfaces, versions, and local compatibility require confirmation.
  • Public source
  • Exact FDA submission
  • Checked 2026-09-01

Interoperability terms explicitly reported in the exact-submission ACR model card; interface versions and local compatibility still require confirmation.

Deployment and data flow
On-premise
  • Public source
  • Exact FDA submission
  • Checked 2026-08-13

Deployment category preserved from the prior exact-submission review; hosting region, data flow, and current commercial configuration still require vendor confirmation.

Security and privacy
Vendor documentation pending
