### C.7.3 Common Series IE Modules

The following Series IE Modules are common to all Composite Image IODs that reference the Series IE.

#### C.7.3.1 General Series Module

Table C.7-5a specifies the Attributes that identify and describe general information about the Series within a Study.

Table C.7-5a. General 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. See Section C.7.3.1.1.1 for Defined Terms.
Series Instance UID | (0020,000E) | 1 | Unique identifier of the Series.
Series Number | (0020,0011) | 2 | A number that identifies this Series.
Laterality | (0020,0060) | 2C | Laterality of (paired) body part examined. Required if the body part examined is a paired structure and Image Laterality (0020,0062) or Frame Laterality (0020,9072) or Measurement Laterality (0024,0113) are not sent. Enumerated Values: R right L left ### Note Some IODs support Image Laterality (0020,0062) at the Image level or Frame Laterality (0020,9072) at the Frame level in the Frame Anatomy functional group macro or Measurement Laterality (0024,0113) at the Measurement level, which can provide a more comprehensive mechanism for specifying the laterality of the body part(s) being examined.
Series Date | (0008,0021) | 3 | Date the Series started.
Series Time | (0008,0031) | 3 | Time the Series started.
Performing Physician's Name | (0008,1050) | 3 | Name of the physician(s) administering the Series.
Performing Physician Identification Sequence | (0008,1052) | 3 | Identification of the physician(s) administering the Series. One or more items are permitted in this sequence. If more than one Item, the number and order shall correspond to the value of Performing Physician's Name (0008,1050), if present.
>Include Table 10-1 “Person Identification Macro Attributes Description” |
Protocol Name | (0018,1030) | 3 | User-defined description of the conditions under which the Series was performed. ### Note This attribute conveys series-specific protocol identification and may or may not be identical to the one presented in the Performed Protocol Code Sequence (0040,0260).
Series Description | (0008,103E) | 3 | Description of the Series
Series Description Code Sequence | (0008,103F) | 3 | A coded description of the Series. Only a single Item is permitted in this sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID is defined.
Operators' Name | (0008,1070) | 3 | Name(s) of the operator(s) supporting the Series.
Operator Identification Sequence | (0008,1072) | 3 | Identification of the operator(s) supporting the Series. One or more items are permitted in this sequence. If more than one Item, the number and order shall correspond to the value of Operators' Name (0008,1070), if present.
>Include Table 10-1 “Person Identification Macro Attributes Description” |
Referenced Performed Procedure Step Sequence | (0008,1111) | 3 | Uniquely identifies the Performed Procedure Step SOP Instance to which the Series is related. Only a single Item is permitted in this sequence.
>Include Table 10-11 “SOP Instance Reference Macro Attributes” |
Related Series Sequence | (0008,1250) | 3 | Identification of Series significantly related to this Series. One or more Items are permitted in this Sequence. ### Note For example, for a combined CT and PET acquisition, the CT images and PET images would be in separate series that could cross-reference each other with multiple purpose of reference codes meaning same anatomy, simultaneously acquired and same indication. The related series may have different Frames of Reference and hence require some sort of registration before spatial coordinates can be directly compared. This attribute is not intended for conveying localizer reference information, for which Referenced Image Sequence (0008,1140) should be used.
>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.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | Defined CID 7210 “Related Series Purposes of Reference”.
Body Part Examined | (0018,0015) | 3 | Text description of the part of the body examined. See Annex L “Correspondence of Anatomic Region Codes and Body Part Examined Defined Terms” in PS3.16 for Defined Terms ### Note Some IODs support the Anatomic Region Sequence (0008,2218), which can provide a more comprehensive mechanism for specifying the body part being examined.
Patient Position | (0018,5100) | 2C | Patient position descriptor relative to the equipment. Required for images where Patient Orientation Code Sequence (0054,0410) is not present and whose SOP Class is one of the following: CT ("1.2.840.10008.5.1.4.1.1.2") or MR ("1.2.840.10008.5.1.4.1.1.4") or Enhanced CT ("1.2.840.10008.5.1.4.1.1.2.1") or Enhanced MR Image ("1.2.840.10008.5.1.4.1.1.4.1") or Enhanced Color MR Image ("1.2.840.10008.5.1.4.1.1.4.3") or MR Spectroscopy ("1.2.840.10008.5.1.4.1.1.4.2") Storage SOP Classes. May be present for other SOP Classes if Patient Orientation Code Sequence (0054,0410) is not present. See Section C.7.3.1.1.2 for Defined Terms and further explanation.
Smallest Pixel Value in Series | (0028,0108) | 3 | The minimum value of all images in this Series.
Largest Pixel Value in Series | (0028,0109) | 3 | The maximum value of all images in this Series.
Request Attributes Sequence | (0040,0275) | 3 | Sequence that contains attributes from the Imaging Service Request. One or more Items are permitted in this sequence.
>Include Table 10-9 “Request Attributes Macro Attributes” | No Baseline CID is defined.
Include Table 10-16 “Performed Procedure Step Summary Macro Attributes” | No Baseline CID is defined.
Anatomical Orientation Type | (0010,2210) | 1C | The anatomical orientation type used in instances generated by this equipment. Enumerated Values: BIPED QUADRUPED Required if the patient is an animal and the anatomical frame of reference is not bipedal. May be present otherwise. See Section C.7.6.1.1.1 and Section C.7.6.2.1.1. ### Note If this Attribute is not present, the default human standard anatomical position is used to define the patient orientation of projection images and the patient coordinate system of cross-sectional images.

### Note

1. If any Performed Procedure Step SOP Class is supported as an SCU by a Storage SCU, the SCU is strongly encouraged to support the attribute Referenced Performed Procedure Step Sequence (0008,1111). This attribute references the Performed Procedure Step SOP Instance, and extraction of this Attribute from a Composite Instance may allow retrieval of the Performed Procedure Step SOP Instance.

2. If the Storage SCU does not conform to any Performed Procedure Step SOP Class, it is still advisable to include the attributes Performed Procedure Step Start Date (0040,0244), Performed Procedure Step Start Time (0040,0245) and Performed Procedure Step Description (0040,0254) into the Composite Instances.

###### C.7.3.1.1.2 Patient Position

Patient Position (0018,5100) specifies the position of the patient relative to the imaging equipment space. This attribute is intended for annotation purposes only. It does not provide an exact mathematical relationship of the patient to the imaging equipment.

When facing the front of the imaging equipment, Head First is defined as the patient's head being positioned toward the front of the imaging equipment. Feet First is defined as the patient's feet being positioned toward the front of the imaging equipment. Prone is defined as the patient's face being positioned in a downward (gravity) direction. Supine is defined as the patient's face being in an upward direction. Decubitus Right is defined as the patient's right side being in a downward direction. Decubitus Left is defined as the patient's left side being in a downward direction.

Defined Terms:
