Conformant Application Entities shall include in the DICOMDIR File a Basic Directory IOD containing Directory Records at the Patient and subsidiary levels appropriate to the SOP Classes in the File-set.
Note: DICOMDIRs with no directory information are not allowed by this Application Profile.
Table A.3-2 specifies the type of Directory Records that shall be supported and the additional associated keys. Refer to the Basic Directory IOD in PS 3.3.
Table A.3-2STD-XABC-CD ADDITIONAL DICOMDIR KEYS
|Key Attribute||Tag||Directory Record Type||Type||Notes|
|Patient’s Birth Date||(0010,0030)||PATIENT||2|
|Performing Physicians’ Name||(0008,1050)||SERIES||2|
|Icon Image Sequence||(0088,0200)||IMAGE||1|
|Referenced Image Sequence||(0008,1140)||IMAGE||1C||Required if the SOP Instance referenced by the Directory Record has an Image Type (0008,0008) of BIPLANE A or BIPLANE B.|
|>Referenced SOP Class UID||(0008,1150)||IMAGE||1C||Required if Referenced Image Sequence (0008,1140) is present|
|>Referenced SOP Instance UID||(0008,1155)||IMAGE||1C||Required if Referenced Image Sequence (0008,1140) is present|
Directory Records of type IMAGE shall include Icon Images. The icon pixel data shall be supported with Bits Allocated (0028,0100) equal to 8 and Row (0028,0010) and Column (0028,0011) attribute values of 128.
Notes: 1. This icon size is larger than that recommended in PS 3.10 because the 64x64 icon would not be clinically useful for identifying and selecting x-ray angiographic images.
2. For multi-frame images, it is recommended that the icon image be derived from the frame identified in the Representative Frame Number attribute (0028,6010), if defined for the image SOP Instance. If the Representative Frame Number is not present, a frame approximately one-third of the way through the multi-frame image should be selected. The process to reduce a 512x512 image to a 128x128 image is beyond the scope of this standard.
