HAGRad Viewer
Cardiac CT DICOM review with window/level, zoom, pan, measurements, MPR, profile analysis, and ZIP exports.
Cardiac CT research software
HAGRad
Open-Source Framework for Advanced Cardiac CT Research
HAGRad is a local DICOM research environment for cardiac CT review, multi-planar reformation, quantitative measurement, coronary CTA image-quality analysis, EAT quantification, and workflow prototyping.
Research Use Only. HAGRad is not intended for clinical diagnosis, treatment decisions, or patient care.
Modules
Focused workflows for cardiovascular imaging research
HAGRad keeps the core viewer familiar while separating specialized measurements into modules that can evolve independently.
CCTA Image Quality
Objective coronary CTA ROI measurements, subjective reader scoring, editable protocols, SNR/CNR metrics, and structured export.
Epicardial Adipose Tissue
Pericardial contouring, HU thresholding, multi-reconstruction comparison, and measurement export for EAT research.
Quantitative Coronary Angiography
Invasive angiography frame selection, vessel segmentation workflow, stenosis measurements, and research export bundles.
Screenshots
Visual workflow examples
Representative screenshots show how HAGRad converts image review into structured research outputs.
HAGRad EAT
Epicardial adipose tissue summary report with volume, density, review coverage, and segmented representative slices.
Core Viewer
Axial cardiac CT review with editable measurement overlays and quantitative stent-lumen profile analysis.
CCTA IQ
Objective image-quality comparison across coronary CTA reconstructions using ROI attenuation and noise measurements.
CCTA IQ Summary
Per-reconstruction output with representative ROIs, objective signal/noise graphs, and subjective quality scoring.
QCA
Still-frame invasive angiography analysis with vessel overlay, stenosis measurements, and diameter profile output.
