A.8.3 Multi-frame Grayscale Byte SC Image Information Object Definition

A.8.3.1 Multi-frame Grayscale Byte Image IOD Description

The Multi-frame Grayscale Byte Secondary Capture (SC) Image Information Object Definition (IOD) specifies Grayscale Byte images that are converted from a non-DICOM format to a modality independent DICOM format.

This IOD is typically used for screen captured images for modalities that have pixel values of 8 bits, but may also be appropriate for scanned grayscale documents.

A.8.3.2 Multi-frame Grayscale Byte SC Image IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Information Model that directly reference the Secondary Capture Image family of IODs. The Frame of Reference IE, Overlay IE, Modality LUT IE and Curve IE are not components of this IOD.

A.8.3.4 Multi-frame Grayscale Byte SC Image IOD Content Constraints

The VOI LUT module is required if the VOI LUT stage is not an identity transformation. Support for both window and LUT is mandatory. The output grayscale space is defined to be in P-Values.

Note: If the VOI LUT module is absent, then the stored pixel values are in P-Values.

In the Image Pixel Module, the following constraints apply:

- Samples per Pixel (0028,0002) shall be 1

- Photometric Interpretation (0028,0004) shall be MONOCHROME2

- Bits Allocated (0028,0100) shall be 8

- Bits Stored (0028,0101) shall be 8

- High Bit (0028,0102) shall be 7

- Pixel Representation (0028,0103) shall be 0

- Planar Configuration (0028,0006) shall not be present

The Overlay module shall not be present.
