Reference Coordinate System​

TheRCSisthespatialcoordinatesysteminaDICOMFrameofReference.Itisthechosenorigin,​

(RCS)​

orientation and spatial scale of an Image IE in a Cartesian space. The RCS is a right-handed​

Cartesiancoordinatesystemi.e.,thevectorcrossproductofaunitvectoralongthepositivex-axis​

and a unit vector along the positive y-axis is equal to a unit vector along the positive z-axis. The​

unit length is one millimeter. Typically, the Image IE contains a spatial mapping that specifies the​

relationship of the image samples to the Cartesian spatial domains of the RCS.​

Ophthalmic Coordinate System​

The Ophthalmic Coordinate System is used as the Frame of Reference that establishes the​

(OCS)​

spatial relationship relative to the corneal vertex. The corneal vertex is the point located at the​

intersection of the patient's line of sight (visual axis) and the corneal surface. See​

Section C.8.30.3.1.4 for further explanation.​

Fiducial​

to establish the spatial relationship between similar objects.​

Fiducial Point​

A Fiducial Point defines a specific location of a Fiducial. A Fiducial Point is relative to an image​

or to an RCS.​

Multi-Planar Reconstruction​

Also called Multi-Planar Reformatting. A data visualization created by sampling volume data,​

(MPR)​

typically represented by a stack of image planes, that lies in the neighborhood of the intersection​

of the volume with a plane, curved plane, slab or curved slab.​

Planar Multi-Planar​

An MPR where the samples are centered on a single plane intersected with the volume.​

Reconstruction (Planar MPR)​

Volumetric Presentation State​

A Presentation State that defines a transformation from 3D spatial input data (volume) to 2D​

(VPS)​

spatial output data, with or without affecting other dimensions such as temporal.​

Volumetric Presentation State​

Volumetric Presentation View​

A presentation, with two spatial dimensions, of volume data.​

Unique Device Identifier (UDI)​

An alphanumeric identifier issued by the unique device identification system established by the​

FDA to label and identify devices through distribution and use. See http://www.fda.gov/udi.​

Content Item​

A node in the Content Tree of a DICOM SR document, consisting of either a container with a​

coded Concept Name, or a name-value pair with a coded Concept Name and a Concept Value.​

Content Tree​

The tree of Content Items of a DICOM SR document.​

3.22 Miscellaneous Definitions Definitions​

Externally-Sourced Data Set​

A collection of data that has been obtained from or is defined by an entity separate from the​

system creating an object.​
