| 21 | | 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. |
| 22 | | 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. |
| 23 | | Procedure Approach Body Structure | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The approach body site used for this procedure. Multiple locations are allowed. |

| 39 | | Treatment Applicator Type | hl7.fhir.us.codex-radiation-therapy#current | R4 | Radiotherapy Treatment Applicator Type. |
| 40 | | 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. |
