Parallel RT Beam Delimiter Positions Attribute

Tag(300A,064A)
TypeConditionally Required (1C)
KeywordParallelRTBeamDelimiterPositions
Value Multiplicity2-n
Value RepresentationDouble (FD)

One-dimensional positions of the tip in mm of beam delimiters.

If Device Type Code Sequence (3010,002E) contains (130333, DCM, "Single Leaves"), N values shall be provided where N is the Number of Parallel RT Beam Delimiters (300A,0648).

If Device Type Code Sequence contains (130330, DCM, "Jaw Pair") or (130331, DCM, "Leaf Pairs"), 2N values shall be provided where N is the Number of Parallel RT Beam Delimiters (300A,0648). The values shall be grouped by the mounting side identified by the Parallel RT Beam Delimiter Leaf Mounting Side (300A,064F) with the values of RT Beam Delimiter Elements on the negative mounting side first.

The order of values shall correspond to the order of the Parallel RT Beam Delimiter Boundaries (300A,0649).

See Section C.36.2.2.20.1.1, Section C.36.2.2.20.1.2 and Section C.36.2.2.20.1.3.

Required if the conditions in Section C.36.2.2.5.1.1 are satisfied and if Device Type Code Sequence contains (130330, DCM, "Jaw Pair"), (130331, DCM, "Leaf Pairs") or (130333, DCM, "Single Leaves"), and if the Parallel RT Beam Delimiter Opening Mode (300A,064E) is present and does not have the value BINARY.

Section C.36.2.2.20.1.1

C.36.2.2.20.1.1 Geometric Value Attributes

All geometric values in Section C.36.2.2.20.1 are defined in the Beam Modifier Definition Plane.

Section C.36.2.2.20.1.2

C.36.2.2.20.1.2 RT Beam Delimiter Element Positions

For Device Type Code Sequence (3010,002E) values of (130330, DCM, "Jaw Pair") or (130331, DCM, "Leaf Pairs"), the order of values are

N1, N2, Nn

P1, P2, Pn

where N denotes the negative mounting side, P the positive mounting side and the indices increasing corresponding to the order of the values of Parallel RT Beam Delimiter Boundaries (300A,0649).

Section C.36.2.2.20.1.3

C.36.2.2.20.1.3 RT Beam Delimiter Geometry

The definition of the tip positions in Parallel RT Beam Delimiter Positions (300A,064A) or delimiter outline in the RT Beam Delimiter Geometry Sequence (300A,064C) is as defined by the manufacturer and shall be documented in the Conformance Statement. Typically, this will be the radiological or physical edge.

Section C.36.2.2.5.1.1

C.36.2.2.5.1.1 Requirements for Changing Values within RT Control Point Sequence Attributes

This Section specifies when individual Attributes shall be present in a Sequence.

The RT Control Point Sequence specifies a certain order of execution.

At each RT Control Point the value of various Attributes may be specified as an explicit value (which in the case of a type 2C Attribute may be a null value) and if absent remain at the same value as specified previously. There are physical and mechanical implications of specifying a new value as opposed to staying at the same value, for example gear lash, floating point jitter, etc.

At the first Sequence Item in RT Control Point Sequences (i.e., with an RT Control Point Index (300A,0600) equal to 1) all Attributes affected by this Section shall be present if applicable conditions are met.

For Sequence Items other than the first Sequence Item, Attributes shall be present if applicable conditions are met and the value is different from the previously populated value for the same Attribute (in the case of a type 2C Attribute, a null value is considered as a value). The previously populated value is the value from the Item where the Attribute was present with the greatest value of RT Control Point Index (300A,0600) less than the value of the RT Control Point Index (300A,0600) in the current Item.

This means that for an Item in which an Attribute is absent, the application stays at the value of the previously populated Item.

For Sequences inside a RT Control Point Sequence Item, the Sequence shall be present if any of the nested Attributes affected by this Section differ from the corresponding previously populated Item.

For multi-valued Attributes, such as Parallel RT Beam Delimiter Positions (300A,064A), all values shall be present if any value changes.
