A.32.8.4.1 VL Whole Slide Microscopy Image Functional Group Macros Content Constraints​

A.32.8.4.1.1 Referenced Image​

Defined CID for Purpose of Reference Code Sequence (0040,A170) in the Referenced Image Functional Group is CID 8120 “WSI​ Referenced Image Purposes of Reference”.​

A.32.8.4.1.2 Plane Position (Slide)​

Frames shall occupy plane positions in a regular tiling of the Total Image Matrix; the frames may extend beyond the edges of the​ Total Image Matrix. Therefore, the value of Column Position In Total Pixel Matrix (0048,021E) shall be an integer multiple of the value​ of Columns (0028,0011) plus a constant, and the value of Row Position In Total Pixel Matrix (0048,021F) shall be an integer multiple​ of the value of Rows (0028,0010) plus a (possibly different) constant.​

Note​

Pixels beyond the edge of the Total Image Matrix may be encoded with a fixed padding value. For images with MONO-​ CHROME2 Photometric Interpretation, see Pixel Padding Value (0028,0120) in Section C.7.5.1.1.2.​

The encoding of tiles may be sparse; i.e., some tiles may not be encoded in frames. There are no constraints on the ordering of​ frames within the pixel data; each frame specifies its position in the Plane Position (Slide) Functional Group.​

Note​

Different SOP Instances within a Series may have different tiling boundaries and sizes.​

Frames associated with different optical paths may coincide in any spatial dimension.​

A.32.9 Real-Time Video Endoscopic Image IOD​

A.32.9.3 Real-Time Video Endoscopic Image IOD Content Constraints​

The IOD shall not include audio. Captured patient voice or physiological sounds, healthcare professionals' commentary, or environ-​ mental sounds will be transported in a separate IOD.​

A.32.9.3.1 Modality​

The value of Modality (0008,0060) shall be ES.​

Note​

The use of a single value for Modality recognizes the fact that the same acquisition equipment is often used for different​ purposes (e.g., laparoscopy and colonoscopy). This means that Modality is not useful to distinguish one type of endoscopy​ from another when browsing a collection of studies. Therefore, the use of Procedure Code Sequence (0008,1032) and​ Anatomic Region Sequence (0008,2218) in the image instances and in the query response is recommended, though gath-​ ering sufficient information to populate these attributes in an unscheduled workflow environment (i.e.; in the absence of​ Modality Worklist) may require operator intervention.​

A.32.9.3.3 Anatomic Region Sequence​
