2.3.3.1.33. NXcg_roi

Status:

base class, extends NXobject

Description:

Base class for a region-of-interest (ROI) bound by geometric primitives. ...

Base class for a region-of-interest (ROI) bound by geometric primitives.

So-called region-of-interest(s) (ROIs) are typically used to describe a region in space (and time) where an observation is made or for which a computer simulation is performed with given boundary conditions.

Symbols:

The symbols used in the schema to specify e.g. dimensions of arrays. ...

The symbols used in the schema to specify e.g. dimensions of arrays. Use NXcg_primitive and NXcoordinate_system classes to define explicitly the reference frame in which the primitives are defined.
