Interface

Freeview consists of one window. In this window there is the main viewing area, to the left is the control panel, at the top is the toolbar, at the bottom are the cursor and mouse coordinates, and if you are in the "Voxel Edit" mode, there will be a floating "Drawing" toolbox.

Display Window

fv_screenshot.jpg

Here's a look at the program. In this instance, the user has chosen the 2x2 viewing option, and can see all 3 planes plus 3D together in one window. In this view, when you move the red crosshair to a point in one window, the view within the other 3 windows will move to the corresponding slice at those coordinates where the crosshair was placed. In the 3D window (bottom right), you can hold down the left mouse button and rotate the volume by dragging it.

Control Panel

In the control panel on the left you can choose to work with volumes, ROIs, Surfaces and Way Points. Each one has it's own set of controls and options described below.

Volumes

When working with volumes, under Color Map, you can select Grayscale, Heat, Jet, and Lookup Table. Grayscale, Heat and Jet have similar control panel options.

Grayscale, Heat, Jet:

In the panel shown you can see your volumes listed at the top, in this case the volume is called flash23. The box next to the volume name is checked, meaning the volume is active for editing and visible in the viewing screen. The fact that it is highlighted in blue or selected means that any action you take (drawing, editing, rotating, saving, etc.) will happen on this volume.

Below, you can adjust the opacity between 0, completely transparent, and 1, completely opaque. Checking Smoothing display will smooth the edges of anything you have drawn on the volume. Underneath this is the Color Map drop down menu where you can choose Grayscale, Heat, Jet or Lookup Table.

Using the sliding bars for Window, Level, Min, and Max you can adjust the contrast of the volume.

Lookup Table

In the panel shown, Lookup Table has been selected as the Color Map. Here too, you can adjust opacity between 0 and 1 with the sliding bar.

Below that is a list of different brain regions, and their associated colors. From this menu you can choose which brain region you are going to code or label. This is generally used in the Voxel Edit mode (at which point the Drawing Toolbox [described below] will pop up).

ROIs
