A.33.1 Grayscale Softcopy Presentation State IOD
A.33.1.1 Grayscale Softcopy Presentation State IOD Description
The Grayscale Softcopy Presentation State Information Object Definition (IOD) specifies information that may be used to present (display) images that are referenced from within the IOD.
It includes capabilities for specifying:
a.the output grayscale space in P-Values
b.grayscale contrast transformations including modality and VOI LUT
c.mask subtraction for multi-frame images
d.selection of the area of the image to display and whether to rotate or flip it
e.image and display relative annotations, including graphics, text and overlays
Note
This IOD does not support presentation control for a set of images for which the modality LUT varies on a frame-by-frame basis. Other Presentation State IODs (standard or private) may support such images.
A.33.1.2 Grayscale Softcopy Presentation State IOD Entity-Relationship Model
This IOD uses the E-R Model in Section A.1.2, with only the Presentation State IE below the Series IE.
A.33.1.3 Grayscale Softcopy Presentation State IOD Module Table
Table A.33.1-1 specifies the Modules of the Grayscale Softcopy Presentation State IOD.

In the Grayscale Softcopy Presentation State IOD, the Presentation Series Module specializes some Attributes of the General Series Module, the Presentation State Mask Module specializes some Attributes of the Mask Module, and the Presentation State Shutter Module specializes some Attributes of the Bitmap Display Shutter Module and Display Shutter Module.
Note
1.Subtraction between different images is not supported.
2.The Mask Module condition implies that it need not be supported by an SCP that supports presentation states only for single-frame image storage SOP Classes, or instances of multi-frame image Storage SOP Classes that contain only one frame.
3.The Display Shutter may be used to darken image areas that surround important information and exclude extraneous bright areas that increase glare and ambient lighting impairing image interpretation. For example, unexposed areas in aCRimagemightbeobscuredusingtheDisplayShutter,ratherthanpermanentlyreplacingimagepixelsinthoseareas.
4.This IOD does not support the storage of a multi-frame overlay in the IOD itself, but does support selective activation of multi-frame overlays within the referenced images via the Overlay Activation Module.
