DICOM PS3.3 2024d - Information Object Definitions |
---|
This Module defines Attributes of vector graphics and text annotation that shall be made available by a display device to be applied to an image. The graphics and text are defined in position and size relative to the image pixel coordinates or the Specified Displayed Area space (defined in Section C.10.4); in the context of a Volumetric Presentation State IOD, the annotation is relative to the Volumetric Presentation View (e.g., the MPR view defined in Section C.11.26). A Graphic Annotation shall be related to an Image.
See Section A.80.1.4.3 for constraints on Attributes in this Module when used in the Planar MPR Volumetric Presentation State IOD.

The text shall be displayed if any part of the bounding box or anchor point is within the Specified Display Area.
The text need not be confined to within the bounding box, but shall be rendered in a direction from the Top Left Hand Corner (TLHC) of the bounding box to the Bottom Right Hand Corner (BRHC) of the bounding box, even if these coordinates have been specified in an image relative space and then transformed (rotated, flipped or scaled).
Whether the contents of the bounding box completely opacify the underlying image or whether the box is "transparent" is undefined.
For example, an implementation may choose an "exclusive or" style opacification to be sure that the text is discernible over light and dark portions of the image.
Commonly, the region of the bounding box around the text will be rendered "transparently", i.e., the image will be visible, though some implementations may choose to opacify the bounding box behind the text to improve its readability.
An alternative to specifying a bounding box, is to specify an Anchor Point (0070,0014), i.e., some point in an image or Specified Displayed Area that is related to the text. The semantics of this relationship, and the manner of positioning or linking the text to this point, are unspecified.
For example, a description of a feature may be linked to a point in the image, and when that image is displayed, if it is magnified and panned, the rendered text (and any arrow or line drawn in response to Anchor Point Visibility (0070,0015)) might be repositioned as appropriate so as not to be cropped out of the Specified Displayed Area.
As another example, the text could be rendered in a pop-up window when a hypertext link flagged on the displayed image at the location of Anchor Point (0070,0014) is selected.
The bounding box and anchor point need not be defined with the same axis units, i.e., one can be image pixel relative, and the other displayed area relative.
The size, font and rotation of the individual rendered text characters are unspecified.
Graphic Data (0070,0022) contains the points in the graphic annotation, each dimension for the first point, followed by dimensions for second point, etc. For a two dimensional curve: X1, Y1, X2, Y2, etc. The first (X) dimension corresponds to the image or Specified Displayed Area column (horizontal offset), and the second (Y) dimension corresponds to the image or Specified Displayed Area row (vertical offset). The Value Representation of all components of the N-tuple shall be the same. The image or Specified Displayed Area relative drawing space is defined in Graphic Annotation Units (0070,0005).
If Graphic Type (0070,0023) is POINT, then two values (one point) shall be specified and the single point specified is to be drawn.
If Graphic Type (0070,0023) is POLYLINE, then the points are to be interpreted as an n-tuple list of end points between which straight lines are to be drawn.
If Graphic Type (0070,0023) is INTERPOLATED, then the points are to be interpreted as an n-tuple list of 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.
If Graphic Type (0070,0023) is CIRCLE, then exactly two 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.
If Graphic Type (0070,0023) is ELLIPSE, then exactly four points shall be present; the first two points are to be interpreted as the endpoints of the major axis and the second two points as the endpoints of the minor axis of an ellipse, some form of implementation dependent representation of which is to be drawn.
The notion of "open" or "closed" has no inherent meaning in the context of an arbitrary graphic, other than in the condition for the presence of Graphic Filled (0070,0024). The graphic has no semantic notion of an associated observation such as a region of interest, except that which the unformatted text in the same Item may describe.
The choice of pixel value used to represent the graphic on a display is defined in the Graphic Layer Module.
The Attributes of the Compound Graphic Sequence (0070,0209) are described within this section.
For point encoding rules of Graphic Data (0070,0022) See Section C.10.5.1.2.
All graphics are applied after the application of the image rendering pipeline.
Every Item in the Compound Graphic Sequence shall have a Compound Graphic Instance ID (0070,0226) with a value that is unique within this Sequence.
There shall be one or more Items in the Graphic Object Sequence or Text Object Sequence that represents an alternate rendering of the Compound Object Sequence Item. As a linkage for backward compatibility these Items share the same Compound Graphic Instance ID (0070,0226).
Every Compound Graphic has an equivalent rendering encoded as a set of simple graphic objects linked by the Compound Graphic Instance ID (0070,0226). Simple graphic objects are elements such as points, polylines, interpolated lines, circles and ellipses. The equivalent rendering is a set of simple graphic objects to support an SCP that only understands the simple graphical objects.
All Compound Graphics can be rotated by specifying a Rotation Angle (0070,0230) value and a Rotation Point (0070,0273). The convention for rotation is that positive angle values are defined as counterclockwise around Rotation Point (0070,0273).
For the Compound Graphic Type (0070,0294) ELLIPSE, exactly 2 points shall be present inside Graphic Data (0070,0022). The first point is the top/left hand corner (TLHC) and the second point is the bottom/right hand corner (BRHC) of the bounding rectangle (see Figure C.10.5-2).
For the Compound Graphic Type (0070,0294) RECTANGLE, exactly 2 points shall be present inside Graphic Data (0070,0022). The first point is the top/left hand corner of the rectangle (TLHC) and the second point is the bottom/right hand corner (BRHC) of the rectangle (see Figure C.10.5-2).
For the Compound Graphic Type (0070,0294) MULTILINE, the list of points inside Graphic Data (0070,0022) is an n-tuple list of start and end points of straight lines to be drawn (see Figure C.10.5-3).
If Rotation Angle (0070,0230) is present, all points in the MULTILINE are rotated around the same Rotation Point (0070,0273).
For the Compound Graphic Type (0070,0294) CUTLINE or INFINITELINE, exactly two points shall be present inside Graphic Data (0070,0022). The rendering of these lines always extends to the borders of the render area of a view(see Figure C.10.5-4).
In case of a CUTLINE, two arrows shall be drawn perpendicular to the cutline. The arrows ends shall be positioned at the midpoints of each half of the cutline. The arrow heads shall point toward the cutline and shall be drawn in the positive right half-plane of the cutline before rotation. Typically, the arrows indicate the viewing direction for MPR renderings that are referenced by these lines.
Gap Length (0070,0261) defines the diameter of the circular area where the CUTLINE or INFINITELINE is not rendered. Center of the circular area is Rotation Point (0070,0273). Since the dimension units of the Gap Length is DISPLAY, independent of the value of Compound Graphic Units (0070,0282), the length of the gap is not changed by zoom operations on the image performed by the application.
For the Compound Graphic Type (0070,0294) RANGELINE exactly two points shall be present inside Graphic Data (0070,0022).
For the Compound Graphic Type (0070,0294) RULER, exactly two points shall be present inside Graphic Data (0070,0022) defining the ruler line.
Tick Alignment (0070,0274) defines the alignment of the ticks.
BOTTOM - ticks are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
CENTER - ticks are centered on the line.
TOP - ticks are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
Tick Label Alignment (0070,0279) defines the alignment of the tick labels.
BOTTOM - labels are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
TOP - labels are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
The presence, labeling and units of the ticks on the line is application dependent(see Figure C.10.5-7). If present as numerical values, the labels of the ticks shall increase toward the second point.
For the Compound Graphic Type (0070,0294) AXIS, exactly two points shall be present inside Graphic Data (0070,0022) defining the axis line.
The Major Ticks Sequence (0070,0287) specifies the placement and label of the ticks. The rendering of the minor ticks is left to the application.
Tick Alignment (0070,0274) defines the alignment of the ticks.
BOTTOM - ticks are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
CENTER - ticks are centered on the line.
TOP - ticks are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
Tick Label Alignment (0070,0279) defines the alignment of the tick labels.
BOTTOM - labels are aligned to the lower part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
TOP - labels are aligned to the upper part of the line, where the first point of the line is on the left and the line extends horizontally to the right.
For Compound Graphic Type (0070,0294) CROSSHAIR, exactly one point shall be present inside Graphic Data (0070,0022). This point is the origin of the CROSSHAIR (see Figure C.10.5-8).
Tick Alignment (0070,0274) and Tick Label Alignment (0070,0279) are also valid for the CROSSHAIR. Tick rendering is application dependent.
Gap Length (0070,0261) defines the diameter of the circular area around the origin where the CROSSHAIR is not rendered. Since the dimension units of the Gap Length is DISPLAY, independent of the value of Compound Graphics Units (0070,0282), the length of the gap is not changed by zoom operations on the image performed by the application.
Diameter of Visibility (0070,0262) defines the diameter of the circular area around the origin where the CROSSHAIR is rendered. Since the dimension units of the Diameter of Visibility is DISPLAY, independent of the value of Compound Graphic Units (0070,0282), the size of the crosshair is not changed by zoom operations on the image performed by the application.
For the Compound Graphic Type (0070,0294) ARROW, two points shall be present inside Graphic Data (0070,0022). The first point is the anchor point, the second point is the foot point of the arrow(see Figure C.10.5-9). The arrow head style at the anchor point is not specified.
Text Style Sequence (0070,0231) contains the text style for each text object. This Attribute gives recommendations on how the annotation text should be rendered at the display.
Horizontal Alignment (0070,0242) and Vertical Alignment (0070,0243) define the position of the text relative to the bounding box of the text object (see Figure C.10.5-10).
Table C.10-5a specifies the Attributes of the Text Style Sequence Macro.
