### AAAA.5.3 Reconstruction Protocol

Table AAAA.5-3 contains some attributes of the Defined Procedure Protocol in the 3D reconstruction workstation, that includes the Reconstruction Protocol Element.

Table AAAA.5-3. Reconstruction Protocol

Attribute | Tag | Value
--- | --- | ---
SOP Class UID | (0008,0016) | 1.2.840.10008.5.1.4.1.1.200.7 (XA Defined Procedure Protocol Storage)
SOP Instance UID | (0008,0018) | UID_03
Reconstruction Protocol Element Specification Sequence | (0018,9933) |
>Protocol Element Number | (0018,9921) | 1
>Parameters Specification Sequence | (0018,9913) |
>>See Table AAAA.5-3a “First Reconstruction Protocol Element Specification - 3D SUB RECONSTRUCTION”

Table AAAA.5-3a reflects the semantic contents of constraint sequences but not the actual structure of the IOD. The rows in italics clarify the context of the constrained Attributes that follow by indicating which sequence in the performed module contains the constrained Attribute (as specified in the Selector Sequence Pointer).

In this example, the reconstruction device includes the Reconstruction Protocol Element to perform the 3D reconstruction of all the images acquired with the rotational Acquisition Element #3 of the protocol SOP Instance UID "UID_01" in the acquisition device. This is indicated in the attribute Source Acquisition Protocol Element Number (0018,9938) and Referenced SOP Instance UID (0008,1155).
