Attribute Description

Positioner Type

(0018,1508)

1

Enumerated Values:

NONE

CEPHALOSTAT

RIGID

Image Laterality

(0020,0062)

1

Laterality of the region examined.

Enumerated Values:

R

right

L

left

B

both (i.e., midline)

Shall be consistent with any laterality information contained in Primary Anatomic Structure Modifier Sequence (0008,2230) and/or Laterality (0020,0060), if present.

Note

Laterality (0020,0060) is a Series level Attribute and must be the same for all Images in the Series, hence it must be absent if Image Laterality (0020,0062) has different values for Images in the same Series.

Anatomic Region Sequence

(0008,2218)

1

Sequence that identifies the anatomic region of interest in this image.

Only a single Item shall be included in this Sequence.

>Include Table 8.8-1 “Code Sequence Macro Attributes” .

DCID 4016 “Anatomic Region for Intra-oral Radiography”.

>Anatomic Region Modifier Sequence

(0008,2220)

1C

Sequence that refines the anatomic region of interest in this image.

Required if Primary Anatomic Structure Sequence (0008,2228) is not present.

Only a single Item shall be included in this Sequence.

>>Include Table 8.8-1 “Code Sequence Macro Attributes”

DCID 4017 “Anatomic Region Modifier for Intra-oral Radiography”.

Primary Anatomic Structure Sequence

(0008,2228)

1C

Sequence that describes the primary anatomic structures of interest in this image.

See Section C.8.11.9.1.1 for further explanation.

Required if Anatomic Region Modifier Sequence (0008,2220) is not present.

One or more Items shall be included in this Sequence.

>Include Table 8.8-1 “Code Sequence Macro Attributes” .

DCID 4026 “Primary Anatomic Structure for Intra-oral and Craniofacial Radiography - Teeth”. See Section C.8.11.9.1.1 for further explanation.

C.8.11.9.1.1 Primary Anatomic Structure Sequence

DCID 4026 “Primary Anatomic Structure for Intra-oral and Craniofacial Radiography - Teeth”. This Context Group includes DCID 4018 “Primary Anatomic Structure for Intra-oral Radiography (Permanent Dentition - Designation of Teeth)”, for permanent dentition, DCID 4019 “Primary Anatomic Structure for Intra-oral Radiography (Deciduous Dentition - Designation of Teeth)” for deciduous dentition and DCID 4025 “Primary Anatomic Structure for Intra-oral Radiography (Supernumerary Dentition - Designation of Teeth)” for supernumerary dentition.

These Context Groups contain concepts that are mapped to ISO 3950-2010, which describes a designation of permanent and deciduous dentition using a two digit code, the first digit of which designates a quadrant, and the second digit a tooth.

The teeth imaged shall be listed as multiple Items in the Primary Anatomic Structure Sequence (0008,2228).
