The Angiographic Lesion Analysis Template consists of a CONTAINER providing quantitative arterial analysis measurements derived for an obstruction in a total analyzed segment.
Table TID 3215. Angiographic Lesion Analysis
Set of user defined reference position for method that requires local reference position. 

Distance of local reference position from an arbitrary landmark. 

The reference diameter for the arterial lesion calculated with the applicable reference method 

The reference area for the arterial lesion calculated with the applicable reference method 

The diameter measurement at the start of the reconstruction line in the diameter graph (TID 3214 “Analyzed Segment” Row 14) 

The diameter measurement at the end of the reconstruction line in the diameter graph (TID 3214 “Analyzed Segment” Row 14) 

The graph with the calculated cross sectional area results based on the densitometric method 

The cross sectional area measurements calculated based on the densitometric method 

The cross sectional area measurement at the start of the reconstruction line in the area graph 

The cross sectional area measurement at the end of the reconstruction line in the area graph 

The diameter stenosis is calculated as follows: (Reference Luminal Diameter  Minimum Luminal Diameter / Reference Luminal Diameter) * 100% 

The circular and the densitometric area stenosis are calculated respectively as: (Reference Vessel Lumen CrossSectional Area  Minimum Luminal Circular Area / Reference Vessel Lumen CrossSectional Area) * 100%(Reference Vessel Lumen CrossSectional Area  Minimum Luminal Densitometric Area / Reference Vessel Lumen CrossSectional Area) * 100% 

Estimated lumen volume between proximal border and distal border of lesion (TID 3218 “Position in Arterial Segment”, row 1 and 2) 

Secondary Capture image with obstruction analysis contour. No purpose of reference is specified.
