Type

Attribute Description

Number of Acquisition Devices

(3002,0116)

1

Number of Acquisition Devices defined in the Acquisition Device Sequence (3002,0117).

Acquisition Device Sequence

(3002,0117)

1C

Devices used to generate images. The devices may be physical imaging devices that performed acquisition or virtual imaging devices for which acquisition was simulated.

Required if the Number of Acquisition Devices (3002,0116) has a non-zero value.

The number of Items included in this Sequence shall equal the value of Number of Acquisition Devices (3002,0116).

>Include Table C.36.2.2.3-1 “RT Accessory Device Identification Macro Attributes”

CID is specified at invocation.

>Device Index

(3010,0039)

1

Index of the Device in this Sequence.

The value shall start at 1 and increase monotonically by 1.

>Referenced Defined Device Index

(300A,0602)

1C

Device Index value that links the device defined by this Sequence Item to the corresponding device in another SOP Radiation Instance. The description of the two devices may or may not be the same.

The value is the index of a device in the Acquisition Device Sequence (3002,0117) within the single SOP Instance referenced by a SOP Instance Sequence defined in the Macro invocation.

Required if the Instance referenced in the SOP Instance Sequence contains the device that corresponds to the device defined by this Sequence Item.

See Section C.36.2.2.19.1.5.
