A free text description of the type of correction or calibration performed.
In the case of correction, the text might include description of the assumptions made about the body part and geometry and depth within the Patient.
in the case of calibration, the text might include a description of the fiducial and where it is located (e.g., "XYZ device applied to the skin over the greater trochanter").
Though it is not required, the Device Module may be used to describe the specific characteristics and size of the calibration device.
Required if Pixel Spacing Calibration Type (0028,0A02) is present.
Table C.7-18 describes the Attributes of devices or calibration objects (e.g., catheters, markers, baskets) that are associated with a Study and/or image.
