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.
