C.8.8.21.1 Control Point Machine Delivery Parameters
All treatment machine delivery parameters (including table angles and positions) in the RT Treatment Session Record Module shall be specified as absolute, not relative, values at the Control Point.
C.8.8.21.2 Specified and Delivered Meterset Values
C.8.8.21.2.1 Beam Level
The value of Specified Primary Meterset (3008,0032) shall be the value specified by Beam Meterset (300A,0086) in the corresponding Fraction Group of the referenced RT Plan. The referenced RT Plan is found in the Referenced RT Plan Sequence (300C,0002), and within this plan the Fraction Group is found using the Referenced Fraction Group Number (300C,0022) in this Module. The Beam is found in the referenced RT Plan using the Referenced Beam Number (300C,0006) in the same Item of the Treatment Session Beam Sequence (3008,0020) as the Specified Primary Meterset (3008,0032).
The value of Delivered Primary Meterset (3008,0036) shall be the accumulated value of the delivered Meterset across all Control Points, which is recorded in this Item of the Treatment Session Beam Sequence (3008,0020).
Note that, for example, when a partial treatment has occurred and resumption(s) have been delivered that complete delivery of all control points remaining, the sum of the Delivered Primary Meterset (3008,0036) values in all RT Beams Session Records for the beam in question and the fraction being treated will match the specified Meterset for the whole fraction.
C.8.8.21.2.2 Control Point Level
Specified Meterset (3008,0042) contains the MU as specified in the corresponding RT Plan at a given control point.
Delivered Meterset (3008,0044) shall contain one of the following three values:
-
the Meterset value at which the delivery of the current beam started
-
the Specified Meterset
-
the Meterset value at which the delivery of the current beam ended
Control points that already have been treated in an earlier session shall contain the Meterset value at which the delivery of the current beam started. Control points that have been completely treated during the current session shall contain the Specified Meterset value for this Control Point. Control Points that have not yet been treated or not completely shall contain the total delivered MU up to the point where the interruption has occurred (i.e., the last control point treated).
This can be expressed by the following equation:
with
- DelMS[CPn]
-
Delivered Meterset value at control point n
- SpecMS[CPn]
-
Specified Meterset value at control point n
- StartMS
-
Meterset value where delivery of current beam started
- EndMS
-
Meterset value where delivery of current beam ended
By this definition it is unambiguously recorded, which 'segments' of control points have been delivered in case of partial treatments.

Note
-
Recording an extra tuning spot is considered reordering, even if the spots were delivered in the prescribed order. If re-painted spots (i.e., Number of Paintings (300A,039A) > 1) are recorded separately, then this is also considered reordering.
-
Treatment Termination Code (3008,002B) was previously included in this Module but has been retired. See PS3.3-2023a. The RT Treatment Termination Reason Code Sequence (300A,0715) and Machine-Specific Treatment Termination Code Sequence (300A,0716) should be used for machine readable codes and Treatment Termination Description (300A,0730) for human readable text respectively.
C.8.8.26.1 Specified and Delivered Meterset Values
Specified and Delivered Meterset values on beam and control point level shall be handled as specified for RT Beams Session records in Section C.8.8.21.2.
C.8.8.26.2 Scan Spot Prescribed Indices
Scan Spot Prescribed Indices (300A,0391) are used to associate each delivered spot with its corresponding prescribed spot. If the ordering information is unknown, both Scan Spot Reordered (300A,0393) and Scan Spot Prescribed Indices (300A,0391) shall be absent.
There are various cases how the scan spots are delivered in comparison with the prescribed spot order.
Following are various examples specifying how the scan spot prescribed index shall be used.
C.8.8.26.2.1 Content of RT Ion Plan for following Use Cases
It is assumed that the RT Ion Plan contains the following spot positions in the Scan Spot Position Map (300A,0394) and related Scan Spot Meterset Weights (300A,0396).
The following table is a representation of the prescription where "w" represents the Scan Spot Meterset Weight.

The prescription does not contain an explicit index for the scan spot order. The index is defined implicitly by the order of the spots within the prescribed map. The implicit index starts at 0.
The following examples specify some different cases of delivered scan spot order that can then be supported using the spot index in the RT Ion Beams Treatment Record.
C.8.8.26.2.2 Treatment Recording Use Cases
The following tables contain 3 columns as follows:
First column: The delivered Scan Spot Position in the Scan Spot Position Map (300A,0394). In this column the spot positions are annotated as they have been delivered. The index following the coordinate character refers to the index in the RT Ion Plan. If the index is appended, it shows that 2 or more delivered scan spots refer to the same Scan Spot Position in the RT Ion Plan.
Second column: The Scan Spot Meterset Delivered (3008,0047). The Meterset Delivered is indicated by 'm'.
Third column: The Scan Spot Prescribed Indices (300A,0391) referring to the position in the Scan Spot Meterset Weights (300A,0396) of the referenced RT Ion Plan are indicated as they are recorded in the RT Ion Beams Treatment Record.
C.8.8.26.2.3 Use Case 1: No pause, no spot reordering, no spot splitting, no repainting
This use case is an example where the spots are treated in the exact order as prescribed in the RT Ion Plan.

Since there was no re-ordering, Scan Spot Reordered (300A,0393) is absent or NO and Scan Spot Prescribed Indices (300A,0391) shall be absent.
C.8.8.26.2.4 Use Case 2: Pause
This use case is an example of a spot broken up into two reported spots due to a pause in the middle of treatment.

The pause occurred during the delivery of the 3rd spot. When the delivery resumed, the spot was not located at the same position prior to the pause. The notations x3a,y3a represent the position of the spot prior to the pause. x3b,y3b represent the position of the resumed spot. Both spots refer to the same prescribed spot. The Meterset m3a represents the measured Meterset prior to the pause and m3b represents the measured Meterset after resumption.
C.8.8.26.2.5 Use Case 3: Tuning Spot
Some delivery systems use a tuning spot (aka pulse) to adjust the different beam parameters. This tuning spot can be delivered at the beginning of the beam or at any time during the beam. The tuning spot may not reach exactly the same position as a prescribed spot.
The suffix 't' indicates a tuning spot.

A tuning spot was delivered at the beginning of a control point. The tuning spot will be present in the treatment record. As it is the first one being delivered for that control point, it will be the first one in the record.
The tuning spot in this example was targeting the 4th spot of the prescription. In the record the Scan Spot Prescribed Indices will refer to the 4th position. As the tuning spot may not match the prescribed position, it will have its own coordinates represented by the suffix 't'.
C.8.8.26.2.6 Use Case 4: Repainting
Use case demonstrating how re-paints of the spot map within the same control point can be represented.
The suffix 'p<n>' indicates a painting iteration.

When repainting is requested (Number of Paintings (300A,039A) is greater than 1), the record shall contain each of the delivered paintings.
In the example, painting was performed three times. Each repainted spot is described by the Scan Spot Position, the Delivered Metersets of the specific painting, and the Scan Spot Prescribed Indices.
C.8.8.26.2.7 Use Case 5: Spot Reordering
In this use case, the number of spots remains the same, but they are simply treated in a different order than planned.

When Scan Spot Re-Ordering is allowed, the spots are listed in the order of the delivery and reference the Scan Spot Prescribed Indices.
C.8.8.26.2.8 Use Case 6: Combination
This use case is a combination of all the above including tuning spots, repaints, and additional re-ordering.
The suffix 't' indicates a tuning spot.
The suffix 'p<n>' indicates a painting iteration.
The suffix '(r)' in Scan Spot Prescribed Indices (300A,0391) indicates that the spot has been re-ordered.

The repainting is represented by recording the spot multiple times and referencing to the same scan spot prescribed index.
The tuning pulse is recorded for the first two paintings and references the scan spot prescribed index of the spot being used for tuning.
The order of the spots is the spot order actually delivered.
The third painting did not deliver all the prescribed spots because some of the spot Metersets were below the minimum deliverable Meterset of the machine.
