This Code system is used in the following value sets:

The type of coordinates describing a 2D image region.

This case-sensitive code system http://hl7.org/fhir/imagingselection-2dgraphictype defines the following codes:

point POINTA single location denoted by a single (x,y) pair.btn btn
polyline POLYLINEA series of connected line segments with ordered vertices denoted by (x,y) triplets; the points need not be coplanar.btn btn
interpolated INTERPOLATEDAn n-tuple list of (x,y) pair end points between which some form of implementation dependent curved lines are to be drawn. The rendered line shall pass through all the specified points.btn btn
circle CIRCLETwo points shall be present; the first point is to be interpreted as the center and the second point as a point on the circumference of a circle, some form of implementation dependent representation of which is to be drawn.btn btn
ellipse ELLIPSEAn ellipse defined by four (x,y) pairs, the first two pairs specifying the endpoints of the major axis and the second two pairs specifying the endpoints of the minor axis.btn btn

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
