Referenced Dose Reference Number Attribute

TypeRequired (1)
Value Multiplicity1
Value RepresentationInteger String (IS)

Uniquely identifies Dose Reference specified by Dose Reference Number (300A,0012) within Dose Reference Sequence (300A,0010) in RT Prescription Module.

RT Prescription Module

C.8.8.10 RT Prescription Module

Table C.8-46. RT Prescription Module Attributes

Attribute Name



Attribute Description

Prescription Description



User-defined description of treatment prescription.

Dose Reference Sequence



Sequence of Dose References.

One or more Items are permitted in this Sequence.

>Dose Reference Number



Identification number of the Dose Reference. The value of Dose Reference Number (300A,0012) shall be unique within the RT Plan in which it is created.

>Dose Reference UID



A unique identifier for a Dose Reference that can be used to link the same entity across multiple RT Plan objects.

>Dose Reference Structure Type



Structure type of Dose Reference.

Defined Terms:


dose reference point specified as ROI


dose reference volume specified as ROI


point specified by Dose Reference Point Coordinates (300A,0018)


dose reference clinical site

>Dose Reference Description



User-defined description of Dose Reference.

>Referenced ROI Number



Uniquely identifies ROI representing the dose reference specified by ROI Number (3006,0022) in Structure Set ROI Sequence (3006,0020) in Structure Set Module within RT Structure Set in Referenced Structure Set Sequence (300C,0060) in RT General Plan Module. Required if Dose Reference Structure Type (300A,0014) is POINT or VOLUME.

>Dose Reference Point Coordinates



Coordinates (x,y,z) of Reference Point in the Patient-Based Coordinate System described in Section C. (mm). Required if Dose Reference Structure Type (300A,0014) is COORDINATES.

>Nominal Prior Dose



Dose (in Gy) from prior treatment to this Dose Reference (e.g., from a previous course of treatment).

>Dose Reference Type



Type of Dose Reference.

Defined Terms:


treatment target (corresponding to GTV, PTV, or CTV in [ICRU Report 50])


Organ at Risk (as defined in [ICRU Report 50])

>Constraint Weight



Relative importance of satisfying constraint, where high values represent more important constraints.

>Delivery Warning Dose



The dose (in Gy) that when reached or exceeded should cause some action to be taken.

>Delivery Maximum Dose



The maximum dose (in Gy) that can be delivered to the dose reference.

>Target Minimum Dose



Minimum permitted dose (in Gy) to Dose Reference if Dose Reference Type (300A,0020) is TARGET.

>Target Prescription Dose



Prescribed dose (in Gy) to Dose Reference if Dose Reference Type (300A,0020) is TARGET.

>Target Maximum Dose



Maximum permitted dose (in Gy) to Dose Reference if Dose Reference Type (300A,0020) is TARGET.

>Target Underdose Volume Fraction



Maximum permitted fraction (in percent) of Target to receive less than the Target Prescription Dose if Dose Reference Type (300A,0020) is TARGET and Dose Reference Structure Type (300A,0014) is VOLUME. See Section C.

>Organ at Risk Full-volume Dose



Maximum dose (in Gy) to entire Dose Reference if Dose Reference Type (300A,0020) is ORGAN_AT_RISK and Dose Reference Structure Type (300A,0014) is VOLUME.

>Organ at Risk Limit Dose



Maximum permitted dose (in Gy) to any part of Dose Reference if Dose Reference Type (300A,0020) is ORGAN_AT_RISK and Dose Reference Structure Type (300A,0014) is VOLUME.

>Organ at Risk Maximum Dose



Maximum dose (in Gy) to non-overdosed part of Dose Reference if Dose Reference Type (300A,0020) is ORGAN_AT_RISK and Dose Reference Structure Type (300A,0014) is VOLUME.

>Organ at Risk Overdose Volume Fraction



Maximum permitted fraction (in percent) of the Organ at Risk to receive more than the Organ at Risk Maximum Dose if Dose Reference Type (300A,0020) is ORGAN_AT_RISK and Dose Reference Structure Type (300A,0014) is VOLUME.

C. Target Underdose Volume Fraction

If the Target Underdose Volume Fraction (300A,0028) is not present, it shall be interpreted as zero.
