Content Item Descriptions

Row 1 | Observation DateTime (0040,A032) of container needs to be flagged with the time of the analysis
Row 6 | Numeric coordinates (x,y) identifying the contour points from proximal to distal of left contour. Left is relative to the direction of the blood flow.
Row 9 | Numeric coordinates (x,y) identifying the contour points from proximal to distal of right contour. Right is relative to the direction of the blood flow.
Row 12, 13 | Positions are relative to the midpoint between the first left and right contour points and measured along the midline between the left and right contour.
Row 14 | The X-axis represents the pixel points of the midline of the vessel from proximal to distal. The points on the midline are not necessarily equidistant.
Row 16 | For each point of the midline of the vessel a measurement value for the diameter is calculated.
Row 17, 18 | The positions in the graph are related to the points on the midline of the vessel.
Row 21 | Secondary Capture image with Arterial Analysis contour.

Definition of Left and Right defined by the direction of the blood flow as in Figure A-4b:
