It includes capabilities for specifying:​ a.​the output color space in PCS-Values​

b.​grayscale contrast transformations including modality and VOI LUT for both the underlying and superimposed image sets​ c.​a color palette to map the transformed grayscale values of the superimposed image set into pseudo-color​

d.​selection of the area of the blended images 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.​

The Softcopy Presentation LUT Module shall not be present in this IOD.​

The VOI LUT Module and Softcopy VOI LUT Module shall not be present in this IOD, since the Presentation State Blending Module​ subsumes their function.​

The Palette Color Lookup Table Module describes the color mapping to be used for the superimposed image set.​

The Displayed Area Module and Graphic Annotation Module specifically identify those images or frames to which they apply, and​ may include images or frames from the underlying or superimposed set.​

The Spatial Transformation Module describes any necessary spatial transformation of the image to be rendered after the blending​ operation.​

The Overlay Plane Module and Overlay Activation Module shall not be present, and any overlays present in the referenced images​ shall not be displayed.​

The Display Shutter Module and Bitmap Display Shutter Module shall not be present, since the underlying image geometry may differ​ between the two sets of images.​

The ICC Profile Module shall always be present. If the color space to be used is not calibrated (i.e., a device-specific ICC Input Profile​ is not available), then an ICC Input Profile specifying a well-known space (such as sRGB) may be specified.​

A.33.5 Basic Structured Display IOD​

A.33.5.1 Basic Structured Display IOD Description​

The Basic Structured Display Information Object Definition (IOD) specifies an instance of a single screen structured display that has​ been created for a Patient. It references specific image or other composite SOP instances from one or more Studies for that Patient,​ or for other Patients for comparison, arranged in a specific presentation layout. Presentation of images within the structured display​ may be controlled by referenced Softcopy Presentation State instances. The structured display may include text annotations.​

In the XA/XRF Grayscale Softcopy Presentation State IOD, the Presentation Series Module specializes some Attributes of the Gen-​ eral Series Module, the XA/XRF Presentation State Mask Module specializes some Attributes of the Mask Module, and the XA/XRF​ 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 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​ aXAimagemightbeobscuredusingtheDisplayShutter,ratherthanpermanentlyreplacingimagepixelsinthoseareas.​

3.​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.​
