Visualisation of medical images

Loading files

There are two ways to open files in Slicer:

1. Using the menu File | Add Data
2. Press the first button on the toolbar, which contains the text DATA

The window that opens is:

Figure 1: Add Data

The options are: to load a single file or to load the contents of a folder. Selecting the option 'Choose directory to add' shows us all the files contained in the folder, when clicking the button we have to indicate the path on the hard disk of the directory where our files are and press the ' Choose '. Then the window will display the files supported with Slicer contained in the folder:

Figure 2: Choose Directory to add

By default all files are selected. You can select / deselect all at once with the box immediately below the 'Choose directory to add' 'button, marked green in the image. If we want to select only one file, the fastest way is to deselect all and then check the box next to the file name that you want to select. Once this is done, pressing the 'OK' button will load the file into Slicer.

If you do not want to use any of the files in the folder or want to select another folder, with the Reset button, the file list shown will be deleted.

File types

NRRD

Corresponds to Nearly Raw Raster Data, is a file format for rendering and processing raster images in 2 and 3 dimensions

VTK

Each vtk file corresponds to a solid. In the case of anatomy is usually placed independently of each organ / structure in a file, to facilitate interactions with them. [Definition]

MRML

Corresponds to Medical Reality Markup Language; based on XML, includes references to 3D data sets and scene properties, used to construct the scene within the program. It is the native Slicer format to save all the elements of a scene in a single file.
