| 26 | | Performer order | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Identifies the relative preference of alternative performers when the request lists multiple performers. |
| 27 | | Point Dose | hl7.fhir.us.codex-radiation-therapy#current | R4 | This flag is true if the dose is determined at a single point.
Point doses are often used to check dose at a specific point in a calculated 3D dose distribution.
Since point doses mostly have a technical role, high-level summaries may decide to exclude them from displays. |
| 28 | | Primary Plan Dose | hl7.fhir.us.codex-radiation-therapy#current | R4 | This flag is true if the dose is the primary plan dose in a radiotherapy treatment plan.
For a single treatment plan, the primary plan dose serves as the main dose value for tracking delivered dose vs. planned dose.
In summaries over multiple treatment plans, the flag indicates that the dose is a primary plan dose in any of the summarized plans. |

| 38 | | Research study | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Indicates that this event is relevant to the specified research study(ies). |
| 39 | | Respiratory Motion Management | hl7.fhir.us.codex-radiation-therapy#current | R4 | Method applied to manage respiratory motion. |
| 40 | | Result Copies To | hl7.fhir.au.base#current | R4 | This extension applies to the ServiceRequest resource and is used to indicate an additional recipient to whom a copy of the outcome of the request (i.e. the results) should be sent. The service requester will typically receive a result as part of the normal processing from the filler of the request and this extension is only relevant for any additional result copy recipients indicated on the request. |
| 41 | | ServiceRequest Precondition | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The condition or state of the patient, prior or during the diagnostic procedure or test, for example, fasting, at-rest, or post-operative. This captures circumstances that may influence the measured value and have bearing on the interpretation of the result. |

| 43 | | ServiceRequest Questionnaire Requested | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Reference to a specific Questionnaire Resource as an ordered item. Allows for ordering a specific questionnaire to be completed. |
| 44 | | Status reason | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Captures the reason for the current state of the resource. |
| 45 | | Treatment Applicator Type | hl7.fhir.us.codex-radiation-therapy#current | R4 | Radiotherapy Treatment Applicator Type. |
| 46 | | Triggered by | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | This resource came into being as a result of expectations set in the referenced Definition resource. I.e. This resource represents a 'step' dictated within the protocol/order set/etc. |
| 47 | | Uniform Fractionation | hl7.fhir.us.codex-radiation-therapy#current | R4 | This flag is true if the fractionation was uniform (i.e., treated with same modality and dose per fraction) and false if the fractionation was mixed. Treatment technique may vary in uniform fractionation.
If the fractionation was uniform, then the correspondence between the physical and biologically effective dose can be determined at the course level.
If the fractionation was not uniform, then the correspondence between the physical and biologically effective dose has to be determined per the phase level.
The flag was introduced to support determination of whether fractionation was uniform when viewing the Radiotherapy Course Summary (without first checking the details of each treatment phase).
This is important in registry use cases to efficiently assess whether checking phase level information is needed. |
