Detailed Description

MRML node for representing a volume (image stack).

Volume nodes describe data sets that can be thought of as stacks of 2D images that form a 3D volume. Volume nodes describe where the images are stored on disk, how to render the data (window and level), and how to read the files. This information is extracted from the image headers (if they exist) at the time the MRML file is generated. Consequently, MRML files isolate MRML browsers from understanding how to read the myriad of file formats for medical data.

◆ GetModifiedSinceRead()

bool vtkMRMLVolumeNode::GetModifiedSinceRead ( )
overridevirtual

Returns true if the node is more recent than the file on disk. This information can be used by the application to know which node has been modified since it has been last read or written. Only storable properties are considered: even if a "non storable" property (e.g. color of a mesh) is modified after the node is being loaded, GetModifiedSinceRead() should return false; the new property value won't be stored on file (only in the MRML scene). By default, calling Modified() on the node doesn't make the node "modified since read", only calling Modified() on StorableModifiedTime does. GetModifiedSinceRead() can be overwritten to handle special storable property modification time.

◆ SetAndObserveImageData()

virtual void vtkMRMLVolumeNode::SetAndObserveImageData ( vtkImageData *  ImageData)
virtual

In the ImageData object origin must be set to (0,0,0) and spacing must be set to (1,1,1). If the variables are set to different values then the application's behavior is undefined. The reason for not using origin and spacing in vtkImageData is that vtkImageData cannot store image orientation, and so it cannot store all the information that is necessary to compute the mapping between voxel (IJK) and physical (RAS) coordinate systems. Instead of storing some information in vtkImageData and some outside, the decision was made to store all information in the MRML node (vtkMRMLVolumeNode::Origin, vtkMRMLVolumeNode::Spacing, and vtkMRMLVolumeNode::IJKToRASDirections).
