If and only if Value Type (0040,A040) is SCOORD:

An ordered set of (column,row) pairs that denote positions in an image specified with sub-pixel resolution such that the origin at the TLHC of the TLHC pixel is 0.0\0.0, the BRHC of the TLHC pixel is 1.0\1.0, and the BRHC of the BRHC pixel is Columns\Rows. The values must be within the range 0\0 to Columns\Rows. The maximum values are those contained in the referenced image in Attributes Columns (0028,0011) and Rows (0028,0010), or in the case of spatial coordinates with Pixel Origin Interpretation (0048,0301) value VOLUME, in Attributes Total Pixel Matrix Columns (0048,0006) and Total Pixel Matrix Rows (0048,0007).

See Section C.18.6.1.1 for further explanation.

If and only if Value Type (0040,A040) is SCOORD3D:

An ordered set of (x,y,z) triplets (in mm and may be negative) that define a region of interest in the patient-relative Reference Coordinate System defined by Referenced Frame of Reference UID (3006,0024). See Reference Coordinate System (RCS).

See Section C.18.9.1.1 for further explanation.

Graphic Data may be used to associate an anatomic or spatial Concept with a defined subset of one or more images. Graphic Data may be explicitly defined as a single point (i.e., to denote the epicenter of an anatomic site or lesion) or more than one point (i.e., representing a set of points or an open or closed polygon).

Spatial coordinates may be used to associate observational data with a set of Image features. Spatial coordinates also may be used to convey coordinates that are input data for a measurement.

Graphic Data may be used to associate an anatomic or spatial Concept with a defined set of patient relative 3D locations in a defined Frame of Reference, independent of any image. Graphic Data may be defined explicitly as a single point (i.e., to denote the epicenter of an anatomic site or lesion) or more than one point (i.e., representing a set of points or an open or closed polygon).
