Shutter Overlay Group Attribute

Tag(0018,1623)
TypeRequired (1)
KeywordShutterOverlayGroup
Value Multiplicity1
Value RepresentationUnsigned Short (US)

Specifies the Group (60xx) of an Overlay stored within the Presentation State IOD that contains the bitmap data, as defined in the Overlay Plane Module Section C.9.2.

Overlay Plane Module

C.9.2 Overlay Plane Module

Table C.9-2 contains Attributes that describe characteristics of an Overlay Plane.

An Overlay Plane describes graphics or bit-mapped text that is associated with an Image. It may also describe a Region of Interest in an Image.

Each Overlay Plane is one bit deep. Sixteen separate Overlay Planes may be associated with an Image.

Overlay data is stored in Overlay Data (60xx,3000). See the Section Repeating Groups in PS3.5 for a description of permitted values of 60xx.

Note

Overlay data stored in unused bit planes of Pixel Data (7FE0,0010) with Samples Per Pixel (0028,0002) of 1 was previously described in DICOM. This usage has now been retired. See PS3.3-2004 and PS3.5-2004.

Attributes describing display of grayscale and color overlays were defined in a previous version of the DICOM Standard. These have now been retired. How an Overlay Plane is rendered is undefined; specifically there is no mechanism to specify with what color or intensity an Overlay Plane is to be displayed, except when rendered under the control of a Softcopy Presentation State SOP Instance.

Table C.9-2. Overlay Plane Module Attributes

Attribute Name

Tag

Type

Attribute Description

Overlay Rows

(60xx,0010)

1

Number of Rows in Overlay.

Overlay Columns

(60xx,0011)

1

Number of Columns in Overlay.

Overlay Type

(60xx,0040)

1

Indicates whether this overlay represents a region of interest or other graphics.

Enumerated Values:

G

Graphics

R

ROI

Overlay Origin

(60xx,0050)

1

Location of first overlay point with respect to pixels in the image, given as row\column.

The upper left pixel of the image has the coordinate 1\1.

Column values greater than 1 indicate the overlay plane origin is to the right of the image origin. Row values greater than 1 indicate the overlay plane origin is below the image origin. Values less than 1 indicate the overlay plane origin is above or to the left of the image origin.

Note

Values of 0\0 indicate that the overlay pixels start 1 row above and one column to the left of the image pixels.

Overlay Bits Allocated

(60xx,0100)

1

Number of Bits Allocated in the Overlay.

The value of this Attribute shall be 1.

Note

Formerly the standard described embedding the overlay data in the Image Pixel Data (7FE0,0010), in which case the value of this Attribute was required to be the same as Bits Allocated (0028,0100). This usage has been retired. See PS3.3-2004.

Overlay Bit Position

(60xx,0102)

1

The value of this Attribute shall be 0.

Note

Formerly the standard described embedding the overlay data in the Image Pixel Data (7FE0,0010), in which case the value of this Attribute specified the bit in which the overlay was stored. This usage has been retired. See PS3.3-2004.

Overlay Data

(60xx,3000)

1

Overlay pixel data.

The order of pixels encoded for each overlay is left to right, top to bottom, i.e., the upper left pixel is encoded first followed by the remainder of the first row, followed by the first pixel of the 2nd row, then the remainder of the 2nd row and so on.

Overlay data shall be contained in this Attribute.

See Section C.9.2.1.1 for further explanation.

Overlay Description

(60xx,0022)

3

User-defined comments about the overlay.

Overlay Subtype

(60xx,0045)

3

Defined Term that identifies the intended purpose of the Overlay Type. See Section C.9.2.1.3 for further explanation.

Overlay Label

(60xx,1500)

3

A user defined text string that may be used to label or name this overlay.

ROI Area

(60xx,1301)

3

Number of pixels in ROI area.

See Section C.9.2.1.2 for further explanation.

ROI Mean

(60xx,1302)

3

ROI Mean.

See Section C.9.2.1.2 for further explanation.

ROI Standard Deviation

(60xx,1303)

3

ROI standard deviation.

See Section C.9.2.1.2 for further explanation.


C.9.2.1 Overlay Attribute Descriptions

C.9.2.1.1 Overlay Type

There are two specific types of overlays. The type is specified in this Attribute.

A Region of Interest (ROI) is a specific use of an Overlay. The overlay bits corresponding to all the pixels included in the ROI shall be set to 1. All other bits are set to 0. This is used to specify an area of the image of particular interest.

A Graphics overlay may express reference marks, graphic annotation, or bit mapped text, etc. A Graphics overlay may be used to mark the boundary of a ROI. If this is the case and the ROI statistical parameters are used, they will only refer to the pixels under the boundaries, not those in the included regions.

The overlay bits corresponding to all the pixels included in the Graphics shall be set to 1. All other bits are set to 0.

C.9.2.1.2 ROI Area, ROI Mean and ROI Standard Deviation

These Attributes contain the statistical parameters of the ROI. The values of these parameters are for the overlay pixel values set to 1.

C.9.2.1.3 Overlay Subtype

Defined Terms:

USER

User created graphic annotation (e.g., operator)

AUTOMATED

Machine or algorithm generated graphic annotation, such as output of a Computer Assisted Diagnosis algorithm

Note

Additional or alternative Defined Terms may be specified in modality specific Modules, such as in the Overlay Subtype.
