Content Item Descriptions

Row 3

Identifies the Calibration program

Row 4

Identifies the Calibration program version

Row 5

Identifies the Calibration program manufacturer

Row 7

Besides a Sphere and a Catheter, a Distance can be identified as a Calibration Object. In this case a distance measurement of a known dimension of the object is used to calculate the pixel size.

Row 8

The catheter size units is also used to specify the size of other calibration objects (e.g., sphere)

Row 9, 10

Spacing in the patient body. Point to a single frame containing the image used for calibration if applicable, the actual measurements may be indicated by a SCOORD (see TID 320 “Image or Spatial Coordinates”, row 3)

Row 11

Secondary Capture image with calibration position. No purpose of reference is specified.
