B.3.4 Other Parameters

This section defines other parameters common to all specific Application Profiles in the STD-XA1K class which need to be specified in order to ensure interoperable media interchange.

B.3.4.1 Image Attribute Values

The attributes listed in Table B.3-3 used within the X-Ray Angiographic Image files have the specified values.

Table B.3-3STD-XA1K Required XA Image Attribute Values

Attribute Tag Value
Modality (0008,0060) XA
Rows (0028,0010) up to 1024 (see below)
Columns (0028,0011) up to 1024 (see below)
Bits Stored (0028,0101) 8, 10, and 12 bits only

Notes: 1. An FSC or FSU, when creating or updating a File-set, Rows or Columns will not exceed a value of 1024. When reading a File-set, an FSR or FSU will accept all values of up to 1024 for Rows or Columns.

2. Photometric Interpretation, Pixel Representation, High Bit, Bits Allocated and Samples per Pixel are defined in the XA IOD.

The attributes listed in Table B.3-4 used within the Secondary Capture Image files have the specified values.

Table B.3-4STD-XA1K Required SC Image Attribute Values

Attribute Tag Value
Rows (0028,0010) up to 1024 (see below)
Columns (0028,0011) up to 1024 (see below)
Samples per Pixel (0028,0002) 1
Photometric Interpretatation (0028,0004) MONOCHROME2
Bits Allocated (0028,0100) 8 bits only
Bits Stored (0028,0101) 8 bits only
High Bit (0028,0102) 7
Pixel Representation (0028,0103) 0000H (unsigned)

Notes: 1. An FSC or FSU, when creating or updating a File-set, Rows or Columns will not exceed a value of 1024. When reading a File-set, an FSR or FSU will accept all values of up to 1024 for Rows or Columns.

2. It is recommend that Referenced Image Sequence (0008,1140) be present if the SC Image is significantally related to XA images and frames stored on the same media, and if present, it should contain references to those images and frames.

Overlay Group 60XX shall not be present in Secondary Capture Images, and Standalone Overlays shall not be referenced by or to Secondary Capture Images used in this profile.

B.3.4.2 Multiframe JPEG Format

The JPEG encoding of pixel data shall use Interchange Format (with table specification) for all frames.

B.3.4.3 Attribute Value Precedence

Retired.
