Clinical Fraction Number Attribute

TypeConditionally Required (1C)
KeywordClinicalFractionNumber
Value Multiplicity1
Value RepresentationUnsigned Short (US)

Identification of the RT Treatment Fraction of the referenced RT Radiation Set Instance that this frame refers to.

Required if the Frame is related to a specific Fraction.

See Section C.36.20.1.2.

Note

Part of the RT Image Frame Context Functional Group Macro with usage: C

Required if the SOP Instance was created for the purpose of controlling the treatment position of the patient.

Section C.36.20.1.2

C.36.20.1.2 RT Radiation Set Delivery Number and Clinical Fraction Number

The Clinical Fraction Number (300A,0705) tracks the clinical progress of treatment delivery.

It is a counter that represents an ordinal count of deliveries of fractions within a radiotherapy treatment serving a given combination of prescriptions.

When it is used prospectively in instructions, the value indicates the ordinal count of the treatment fraction to be delivered in the upcoming treatment session. When the upcoming delivery of therapeutic radiation is intended to consist of the delivery of a complete RT Radiation Set serving the same combination of RT Prescriptions as the previous fraction, the value is incremented. When the upcoming delivery of therapeutic radiation is intended to resume the delivery of a previously incomplete fraction, the value is not incremented, i.e. the value is the same as that of the resumed fraction.

When it is used retrospectively in recording, the value indicates the ordinal count of the treatment fraction which has been delivered.

The RT Radiation Set Delivery Number (300A,0704) tracks the number of times a fraction specified by the referenced RT Radiation Set Instance has been delivered.

When it is used prospectively in instructions, the value indicates the ordinal count of the treatment to be delivered by a referenced RT Radiation Set Instance. When the upcoming delivery of therapeutic radiation is intended to consist of the delivery of a complete RT Radiation Set, the value for that RT Radiation Set is incremented. When the upcoming delivery of therapeutic radiation is intended to resume the delivery of a previously incomplete fraction, the value is not incremented, i.e. the value is the same as that of the resumed fraction.

When it is used retrospectively in recording, the value indicates the ordinal count of deliveries by a referenced RT Radiation Set Instance.

Note

  1. If the same RT Radiation Set is used for all treatments, the values of RT Radiation Set Delivery Number (300A,0704) and the Clinical Fraction Number (300A,0705) have the same values.

  2. For some adaptive treatment approaches, details of the device parameters may be altered at the treatment session to accommodate the current position and shape of the patient. In this case, a new RT Radiation Set SOP Instance is used for the subsequent RT Treatment Fractions serving the same set of RT Prescriptions and the RT Radiation Set Delivery Number (300A,0704) re-starts at 1.

  3. The Clinical Fraction Number (300A,0705) is continuously incremented to reflect the clinical progress of a therapeutic series of treatments. In the RT Radiation Record Set for the last of the intended RT Treatment Fractions, this value will usually be equal to the Number of Fractions (3010,007D) present in the corresponding RT Prescription(s).

Example

RT Radiation Set P contains RT Radiations A, B; Adapted RT Radiations indicated by (') and (") ; RT Radiation Sets created are P, P' and P''.
