Imaging Study Series
A logical set of DICOM instances (such as images or other data objects) that were created by the same modality, during the same session, using the same protocol or acquisition parameters, and that together represent a part of an imaging study.
Attributes
| Attribute | Type | Multiplicity | Attribute note |
|---|---|---|---|
| Imaging Study Series UID | Identifier | 1 | A unique identifier of an imaging study series. |
| Imaging Study Series Modality Code | Codeable Concept | 0..1 | Uniquely specifies the modality of the instances in the series.
Value Set: https://dicom.nema.org/medical/dicom/2018a/output/chtml/part16/sect_CID_29.html |
| Imaging Study Series Number | String | 0..1 | The numeric identifier of this series in the study (e.g., "01234"). |
| Imaging Study Series Number of Instances | Integer | 0..1 | The number of SOP Instances in the Study. The value given may be larger than the number of instance elements this resource contains due to resource availability, security, or other factors. This element should be present if any instance elements are present. |
| Imaging Study Series Body Site Code | Codeable Concept | 0..* | The anatomical site where the medical imaging study was performed (e.g., right hand, left hand, both hands, head, chest).
Value Set: https://fhir.infoway-inforoute.ca/ValueSet/anatomicaloracquiredbodystructurecode |
| Imaging Study Series Laterality Code | Codeable Concept | 0..1 | The side of the body where the medical imaging study was performed (e.g., right, left, midline).
Note:
Body site and laterality are separate elements to support different ways systems capture this information. Some systems include laterality in the body site, while others record it separately. Having both elements helps support consistent use and sharing of the data across systems.
Value Set: https://fhir.infoway-inforoute.ca/ValueSet/lateralitycode |
| Imaging Study Series Body Position Code | Codeable Concept | 0..1 | Uniquely specifies the person’s physical position during the medical imaging study (e.g., supine, standing).
Value Set: To be developed. |
| Imaging Study Series Plane | String | 0..* | The orientation(s) or view(s) used to capture a set of medical images. |
| Imaging Study Series Contrast Phase | String | 0..1 | The contrast-enhancement phase represented by the images in a medical imaging series, based on acquisition timing relative to contrast agent administration and expected contrast distribution. |
