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:
