### H.4.3 Image Box SOP Classes

#### H.4.3.1 Basic Grayscale Image Box SOP Class

##### H.4.3.1.1 IOD Description

The Basic Image Box IOD is an abstraction of the presentation of an image and image related data in the image area of a film. The Basic Image Box IOD describes the presentation parameters and image pixel data that apply to a single image of a sheet of film.

The Basic Grayscale Image Box SOP Instance is created by the SCP at the time the Basic Film Box SOP Instance is created, based on the value of the Basic Film Box Attribute Image Display Format (2010,0010).

The Basic Grayscale Image Box SOP Instance refers to zero or one Image Overlay Box SOP Instance and zero or one Presentation LUT SOP Instance.

##### H.4.3.1.2 DIMSE Service Group

The DIMSE Services applicable to the IOD are shown below.

Table H.4.3.1.2-1. DIMSE Service Group Applicable to Basic Grayscale Image Box

DICOM Message Service Element | Usage SCU/SCP
--- | ---
N-SET | M/M

The meaning of the Usage SCU/SCP is described in Section H.2.4.

### Note

There is no N-CREATE because Instances of the Basic Grayscale Image Box SOP Class are created by the SCP as a result of the N-CREATE of the Film Box SOP Instance.

This Section describes the behavior of the DIMSE Services that are specific for this IOD. The general behavior of the DIMSE Services is specified in PS3.7.

###### H.4.3.1.2.1 N-SET

The N-SET may be used to update an instance of the Basic Grayscale Image Box SOP Class.

###### H.4.3.1.2.1.1 Attributes

The Attributes that may be updated are shown in Table H.4-10.

Table H.4-10. N-SET Attributes

Attribute Name | Tag | Usage SCU/SCP
--- | --- | ---
Image Box Position | (2020,0010) | M/M
Basic Grayscale Image Sequence | (2020,0110) | M/M
>Samples Per Pixel | (0028,0002) | M/M
>Photometric Interpretation | (0028,0004) | M/M
>Rows | (0028,0010) | M/M
>Columns | (0028,0011) | M/M
>Pixel Aspect Ratio | (0028,0034) | MC/M (Required if the aspect ration is not 1\1)
>Bits Allocated | (0028,0100) | M/M
>Bits Stored | (0028,0101) | M/M
>High Bit | (0028,0102) | M/M
>Pixel Representation | (0028,0103) | M/M
>Pixel Data | (7FE0,0010) | M/M
Polarity | (2020,0020) | U/M
Magnification Type | (2010,0060) | U/U
Smoothing Type | (2010,0080) | U/U
Min Density | (2010,0120) | U/U
Max Density | (2010,0130) | U/U
Configuration Information | (2010,0150) | U/U
Requested Image Size | (2020,0030) | U/U
Requested Decimate/Crop Behavior | (2020,0040) | U/U
Referenced Presentation LUT Sequence | (2050,0500) | U/U
>Referenced SOP Class UID | (0008,1150) | U/U
>Referenced SOP Instance UID | (0008,1155) | U/U

The meaning of the Usage SCU/SCP is described in Section H.2.4.

The values of Magnification Type (2010,0060) and Smoothing Type (2010,0080) of a particular image box override the values of Magnification Type and Smoothing Type of the film box.

Values for Referenced Presentation LUT Sequence override any Presentation LUT that may have been set at the Basic Film Box. Values for Min/Max Density override any Density values that may have been set at the Basic Film Box.

###### H.4.3.1.2.1.2 Status

Table H.4.3.1.2.1.2-1 defines the specific status code values that may be returned in a N-SET response. See PS3.7 for additional response status codes.

Table H.4.3.1.2.1.2-1. Status Values for Basic Grayscale Image Box SOP Class

Service Status | Further Meaning | Status Code
--- | --- | ---
Success | Image successfully stored in Image Box | 0000
Warning | Image size larger than image box size, the image has been demagnified. | B604
| Requested Min Density or Max Density outside of printer's operating range. The printer will use its respective minimum or maximum density value instead. | B605
| Image size is larger than the Image Box size. The Image has been cropped to fit. | B609
| Image size or Combined Print Image size is larger than the Image Box size. The Image or Combined Print Image has been decimated to fit. | B60A
Failure | Failed: Image size is larger than image box size | C603
| Failed: Insufficient memory in printer to store the image | C605
| Failed: Combined Print Image size is larger than the Image Box size | C613

###### H.4.3.1.2.1.3 Behavior

The SCU uses the N-SET to request the SCP to update a Basic Grayscale Image Box SOP Instance. The SCU shall only specify the SOP Instance UID of a Basic Grayscale Image Box belonging to the last created Film Box SOP Instance and shall specify the list of Attributes for which the Attribute Values are to be set.

To instruct the SCP to erase the image in the image position, the SCU shall set a zero length and no value in the Attribute Basic Grayscale Image Sequence (2020,0110).

The SCP shall set new values for the specified Attributes of the specified SOP Instance.

### Note

The image in this N-SET supersedes any image previously set in the Image Box.

The SCP shall return the status code of the requested SOP Instance update. The meaning of success, warning, and failure status codes is defined in Section H.2.5.

If Requested Decimate/Crop Behavior (2020,0040) specifies DECIMATE, Magnification Type (2010,0060) specifies NONE, and the image is too large to fit the Image Box, the SCP shall fail the N-SET.

##### H.4.3.1.3 SOP Class Definition and UID

The Basic Grayscale Image Box SOP Class UID shall have the value "1.2.840.10008.5.1.1.4".
