Clinical imaging software
A software upgrade for safer coronary angiography.
CoroLogic is building an on-prem edge platform that restores lower-frame-rate coronary cine through a zero-click DICOM workflow — designed for existing cath labs, no hardware changes.

Dose reduction in coronary angiography has stalled at the hardware level. CoroLogic is building the software layer that closes the gap — acquire less, reconstruct what clinicians need to see.
Why now
Hardware has hit a wall. Software restoration is the next layer.
Interventional cardiologists absorb more cumulative radiation than nearly any other medical specialty. The demand for dose reduction is not new — but the available tools have stalled.
Lowering the frame rate is the simplest lever to cut dose. But it destroys the temporal fidelity clinicians depend on for diagnosis and intervention. So in practice, most operators default back to high-dose protocols.
Detector upgrades and tube filtering from GE, Philips, and Siemens have plateaued. The gains left on the table are not in hardware — they are in what software can reconstruct after acquisition.
The tradeoff today
Clinicians choose between patient safety and diagnostic confidence. Lower frame rate means less radiation — but also jerky, unreliable motion.
Hardware ceiling
Flat-panel detector improvements and X-ray tube refinements have reached diminishing returns. The next meaningful reduction will come from software.
The opportunity
Acquire at a physically lower frame rate, then restore the missing temporal information with generative AI. The dose drops. The diagnostic quality stays.
How it works in a cath lab
Five steps. No workflow disruption. Same DICOM output.
Acquire at lower frame rate
The operator runs angiography at reduced fps. Radiation drops proportionally.
DICOM transfer
Low-frame cine is automatically sent to the edge server. No manual export.
Smart Gating
A classifier identifies contrast-filled segments and filters non-diagnostic frames.
Angio-FILM restoration
Generative frame interpolation reconstructs missing temporal information.
Restored cine returned
Full-rate sequence pushed back via DICOM within seconds. Ready for review.
Real cases
Three retrospective cases. Same anatomy, half the dose.
For each case the raw 7.5 fps acquisition plays on the left; the Angio-FILM restored 15 fps cine plays on the right. Both loops run at their true acquired frame rate, so the visual difference is the actual restoration, not playback speed.
Retrospective sample data from Seoul National University Bundang Hospital. Patient identifiers removed; clips trimmed and downsampled for web display.
Who it's for
Built for three distinct paths to adoption.
For Hospitals & Cath Labs
Reduce radiation exposure for patients and staff without compromising diagnostic image quality. Integrates into existing DICOM workflows with no hardware changes — works with GE, Philips, Siemens, and Canon systems.

How we scale
Two tracks. One mission — make low-radiation coronary angiography the global standard of care.
CoroLogic's commercialization strategy operates on two parallel revenue tracks.
Global Partnership
Seamlessly connected to angiography systems.
CoroLogic works with global angiography equipment manufacturers to integrate Angio-FILM into their imaging ecosystems. Rather than requiring hospitals to adopt new hardware, Angio-FILM connects seamlessly as a software layer within existing cath lab infrastructure. This partnership model enables rapid, scalable deployment across thousands of catheterization labs worldwide.
Direct Hospital Reimbursement
Radiation reduction as a billable clinical innovation.
CoroLogic is actively pursuing direct hospital adoption through Korea's innovative medical technology reimbursement pathway, where each coronary angiography procedure performed using Angio-FILM's radiation-reduction technology can be recognized as a reimbursable clinical service. This B2H (Business-to-Hospital) model establishes a per-procedure revenue stream tied directly to clinical outcomes — a sustainable and scalable business model grounded in measurable patient benefit. Building on reimbursement recognition in Korea, CoroLogic plans to pursue step-by-step entry into reimbursement systems across major global markets.
Pipeline
One core technology. Multiple clinical frontiers.
Building on Angio-FILM's proven core technology, CoroLogic is actively expanding across the following development tracks.
- Real-time processing under 1 second Optimizing the existing 7.5 → 15 fps reconstruction model for sub-second latency, enabling true real-time cath lab deployment.
- Ultra-low dose expansion Extending the frame interpolation model to 5 → 15 fps reconstruction, pushing radiation reduction even further while maintaining diagnostic image quality.
- Cine imaging from fluoroscopy Reconstructing full cine-quality coronary angiography images from fluoroscopic acquisition — a new imaging paradigm within existing workflow.
- Pediatric coronary angiography Adapting Angio-FILM for pediatric cardiac catheterization, where radiation sensitivity demands the highest level of protection.
- Cerebrovascular angiography Expanding AI-based frame interpolation to neuro-interventional procedures.
- Peripheral intervention Applying the Angio-FILM framework to peripheral vascular imaging, broadening the addressable clinical market.
