Product

APEC Vox QCA

AI-powered quantitative coronary angiography designed to deliver rapid, reproducible and auditable coronary measurements directly on a standard hospital computer.

From angiographic image to vessel segmentation, minimum lumen diameter and percentage stenosis in seconds, without cloud processing or specialist hardware.

Research and validation platform. Not a certified medical device; not for clinical use. Intended use

The APEC Vox QCA main window: the study browser on the left, a coronary cine frame in the centre with a two-click measurement drawn on the vessel, and the measurement panel on the right reporting proximal, minimum and distal diameters in millimetres with %stenosis.
APEC Vox QCA — 2D QCA.

Measure

Measurement in seconds.

  • Standard angiographic inputs

    DICOM cine, patient CD exports or single images. The end-diastolic frame is selected automatically.

  • Two-point interaction

    The operator marks the start and end of the segment. Proximal, minimum and distal diameter and %stenosis are reported — in millimetres when the image is calibrated.

  • Seconds, on a standard computer

    A standard laptop or PC, with no GPU, no cloud processing and no upload: images stay on the local machine.

  • Windows 10/11
  • macOS, Apple Silicon
  • No GPU
  • ~2 GB
  • Offline after first launch

Conventional QCA: the semi-automated analysis packages supplied with cath-lab systems and core-lab workstations. APEC Vox QCA is currently a research and validation platform.

In development

Next-generation vessel reconstruction.

We are developing angiography-derived cross-sectional visualisation and lumen reconstruction for additional assessment of vessel geometry. The work is being validated against reference standards — intravascular ultrasound (IVUS) and commercial 3D-QCA — and is not part of the version made available for evaluation.

  • Biplane 3-D reconstruction. Two angiographic views a few dozen degrees apart, and the vessel segment is reconstructed in three dimensions — its true length, without single-projection foreshortening.
  • Lumen geometry. Minimum lumen diameter and area along the reconstructed segment, eccentricity, and the vessel coloured by lumen area.
  • Cross-sectional visualisation. The shape and area of the lumen along the measured segment, derived from the angiogram.
The research build of APEC Vox QCA, biplane reconstruction: a coronary segment measured on view A, the reconstructed vessel drawn in three dimensions and coloured by lumen area, thumbnails of the two projections used, and a reconstruction panel reporting length, minimum lumen diameter and area, eccentricity and the angle between views.
Biplane 3-D reconstruction — research build, in development.

Reconstruction from angiography is not intravascular imaging and does not replace it. These views are research outputs; none of them is validated.

Status

Today, and what it is intended to become.

Current version

Research and validation platform

APEC Vox QCA is currently a research and validation platform, used under a research-use agreement. It is not a certified medical device, it has no diagnostic function, and its output must not be relied on in the care of a patient.

Intended future product

A clinical QCA tool

APEC is developing APEC Vox QCA towards a clinical quantitative coronary angiography tool. It will be offered for clinical use only once its validation is complete and the required regulatory approval is in place.
