### C.8.22 Enhanced PET Modules

This section describes the specific Modules for the Enhanced PET Image IOD.

#### C.8.22.1 Enhanced PET Series Module

The Enhanced PET IODs use the General Series Module, specialized by the Enhanced PET Series Module, to describe the DICOM Series Entity described in Section A.1.2.3, and to define what constitutes a Series for the context of PET device.

Table C.8.22-1 specifies the Attributes that identify and describe general information about the Enhanced PET Series.

Table C.8.22-1. Enhanced PET Series Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Modality | (0008,0060) | 1 | Type of equipment that originally acquired the data used to create the images in this Series. Enumerated Values: PT See Section C.7.3.1.1.1 for further explanation.
Referenced Performed Procedure Step Sequence | (0008,1111) | 1C | Uniquely identifies the Performed Procedure Step SOP Instance to which the Series is related. Only a single Item shall be included in this Sequence. Required if a Performed Procedure Step SOP Class was involved in the creation of this Series.
>Include Table 10-11 “SOP Instance Reference Macro Attributes” |
Related Series Sequence | (0008,1250) | 1C | Identifying the Series that was used for attenuation purposes. See Section C.7.3.1 Required if another Series was used to perform attenuation correction and the SOP Class UID is not "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted). May be present otherwise. One or more Items shall be included in this Sequence.
>Study Instance UID | (0020,000D) | 1 | Instance UID of Study to which the related Series belongs
>Series Instance UID | (0020,000E) | 1 | Instance UID of Related Series
>Purpose of Reference Code Sequence | (0040,A170) | 2 | Describes the purpose for which the reference is made. Zero or more Items shall be included in this Sequence. When absent, implies that the reason for the reference is unknown.
