Description
Xing Guo and colleagues evaluate in 2026 a reconstruction algorithm named ZeeFree. The tool erases stair-step artefacts from coronary CT angiography, the stepwise misalignment that slices of a moving heart leave in later scans. Ninety-five patients were scanned prospectively on a new dual-source scanner, and images were rebuilt with and without the tool for blinded checks. Doctors graded artefact severity, image quality, and diagnostic confidence on five-point scales. Subgroups split by heart rate and body mass.
Most stair-step artefacts vanished in the rebuilt images in the reported share, and scores for severity, quality, and confidence all improved clearly, holding across both subgroup splits. Agreement between tool-based narrowing estimates and invasive angiography, the reference standard, was strong. The authors conclude the tool clearly upgrades heart image usability on this scanner line.
