3D heart viewer
Drag to orbit, scroll to zoom. Toggle between the full heart, the coronary tree, or both. Click any coronary segment to see what it supplies and the best views to image it.
Standard projections
Why this view: Orientation view. Detector directly anterior. Useful for catheter engagement and quick anatomy overview.
No segment selected
Click any vessel segment in the viewer to see what it supplies and the best fluoroscopy views to image it.
LAO vs RAO
Describes where the image intensifier (detector) sits relative to the patient. LAO = patient's left side; RAO = patient's right.
CRA vs CAU
Cranial = detector tilted toward the head, looking down on the heart. Caudal = tilted toward the feet, looking up.
Why so many views?
The coronaries overlap from any single angle. Combining projections eliminates foreshortening and uncovers lesions hidden by overlap.
