Slice view controls allow further customization of which volume is displayed in which view and how.ģD views: Volumes can be displayed in 3D views using Volume rendering module. If multiple volumes are loaded, Data module can be used to choose which one is displayed. Slice views: After loading a volume, it is displayed in slice views by default. 4D volumes are represented as a sequence of 3D volumes, using Sequences extension. Volumes module handles a 2D image as a single-slice 3D image. Tensor volume: each voxel stores a tensor, typically used for storing MRI diffusion tensor image. Or RAS components of a displacement field. ![]() Vector volume: each voxel stores multiple scalar values, such as RGB components of a color image, Storing a segmentation, each label corresponds to a segment. Labelmap volume: each voxel can store a discrete value, such as an index or label most commonly used for Scalar volume: most common type of volume, voxels represent continuous quantity, such as a CT or MRI volume. Volume nodes have subtypes, based on what is stored in a voxel: ![]() Grid spacing (size of voxel) may be different Grid axes are orthogonal to each otherĪnd can be arbitrarily positioned and oriented in physical space. Volumes module provides basic information about volume nodes, can convert between volume types,Īnd allows adjustment of display settings.Ī volume node stores 3D array of elements (voxels) in a rectilinear grid.
