C.34.14 Performed Storage Module

Table C.34.14-1 specifies the Attributes of the Performed Storage Module, which contain storage parameter values for a performed imaging procedure.

Attribute Description

Storage Protocol Element Sequence

(0018,9936)

1

Parameter values for each storage protocol element in the Protocol. The output Instances of the referenced Acquisition or Reconstruction Protocol Elements are stored to the location specified in the Output Information Sequence.

See Section C.34.13.1.

One or more Items shall be included in this Sequence.

The performing system might not support the requested storage protocol or not be configured for the desired destination.

Note

  1. Whether to report failure of one or more of the storage protocol elements as a failure of the protocol is at the discretion of the performing system. The performing system may, additionally or as a fallback, have configured behaviors to store output objects to a default destination or retain them locally.

  2. Similarly, whether the need to complete and record performed storage protocol elements merits delaying the creation of the Performed Protocol objects in which that would be recorded is left to the discretion of the implementation.

  3. Further, there is no intention to record instance storage events that occur beyond those immediately associated with the initial acquisition and reconstruction of the study data.

>Source Acquisition Protocol Element Number

(0018,9938)

1C

A value corresponding to the Element Number (0018,9921) of the Acquisition Protocol Element for which data is stored.

Note

Source Acquisition Protocol Element references are for storage of raw acquisition data. Reconstructed slice storage involves reference to the corresponding Reconstruction Protocol Element in the Source Reconstruction Protocol Element Number (0018,993A).

This may be multi-valued if multiple acquisition protocol element data are being stored together.

Required if Source Reconstruction Protocol Element Number (0018,993A) is not present.

>Source Reconstruction Protocol Element Number

(0018,993A)

1C

The Element Number (0018,9921) corresponding to the Reconstruction Protocol Element for which data is stored.

This may be multi-valued if multiple reconstruction protocol element data are being stored together.

Required if Source Acquisition Protocol Element Number (0018,9938) is not present.

>Source Acquisition Beam Number

(0018,9939)

1C

The Beam Number (300A,00C0) in the Acquisition Protocol Element (specified in Source Acquisition Protocol Element Number (0018,9938) ) for which data is stored. Multiple values may be specified if data for multiple beams is being stored.

Required if:

  • SOP Class UID (0008,0016) has a value of 1.2.840.10008.5.1.4.1.1.200.2 (CT Performed Procedure Protocol Storage) or 1.2.840.10008.5.1.4.1.1.200.8 (XA Performed Procedure Protocol Storage), and

  • Source Acquisition Protocol Element Number (0018,9938) is present and only some of the beams in the Acquisition Protocol Element are to be stored.

SOP Class UID (0008,0016) has a value of 1.2.840.10008.5.1.4.1.1.200.2 (CT Performed Procedure Protocol Storage) or 1.2.840.10008.5.1.4.1.1.200.8 (XA Performed Procedure Protocol Storage), and Source Acquisition Protocol Element Number (0018,9938) is present and only some of the beams in the Acquisition Protocol Element are to be stored.

>Referenced SOP Class UID

(0008,1150)

1C

Uniquely identifies the referenced SOP Class.

Required if the referenced acquisition or reconstruction protocol element is not in this Instance.

Enumerated Values:

1.2.840.10008.5.1.4.1.1.200.2

CT Performed Procedure Protocol Storage

1.2.840.10008.5.1.4.1.1.200.8

XA Performed Procedure Protocol Storage

>Referenced SOP Instance UID

(0008,1155)

1C

The UID of the Protocol Instance containing the element referenced in Source Reconstruction Protocol Element Number (0018,993A) or Source Acquisition Protocol Element Number (0018,9938).

Required if the referenced acquisition or reconstruction protocol element is not in this Instance.

>Output Information Sequence

(0040,4033)

1

References to acquired and reconstructed data objects stored as part of this storage protocol element.

One or more Items shall be included in this Sequence.

Note

It is expected that the storage destinations for Radiation Dose SR Instances and Performed Protocol objects will be managed by direct configuration of the acquisition device rather than using this Sequence on a protocol by protocol basis.
