The technology

Based on the pre-intervention Late Gadolinium-enhanced MRI, the clinician examines the patient's images to decide on the best approach. ADAS 3D LV helps to translate the radiological images to interpret the LV substrate. The Left Ventricle (LV) myocardium is visualized by breaking it into easy-to-understand ‘layers’ to reveal the structure of the scar.

Layers

The layers can be explored interactively, and animations can be created to export into videos.

Corridors detection

ADAS 3D LV analyzes the 3D structure of the myocardium and automatically detects border-zone corridors.

Left: a 3D view of the LV 10% layer, with scar core volume (red) and border-zone (green-yellow). The detected corridor are shown as white lines.

Right: the patient MRI, with a cross at the detected corridor.

The detection method operates in a topological space which makes it suitable for either fast layer-based detection (detecting on a per-layer basis) or for in-depth 3D detection (detecting on the original volume) to account for transmural corridors.
