Description

• Digitized pages from the Talairach atlas are displayed on the left.
• Coronal, transaxial and sagittal slices from a reference T1-weighted MRI volume in Talairach space on the right.
• The current location is denoted by a red mark in all images and is listed in volume and in various Talairach coordinates to the lower-right of the atlas pages. The closest named Talairach structure (and distance from the current location) is listed in green.
• For the volume slices, red 'L' and 'R' letters indicate left/right orientation on coronal and transaxial slices, and red axes in the lower left corner indicate the origin and direction of the x, y and z axes.
• Navigation and display controls are in the lower left corner./li>

Navigation

• The current location may be changed using mouse clicks in the atlas or any volume slice.
• The current location may be specified using any of four (4) methods using the Coordinate input boxes ("Type" and "x y z"). The methods supported are:
  1. "MNI tal" - millimetric Talairach location in the MNI Talairach space
  2. "Tal mm" - millimetric Talariach location
  3. "Tal grid" - Talairach grid notation
  4. "Volume" - voxel location within the MRI volume
  The x, y and z coordinates are space separated.

Atlas Display Options

• "Page" - which pages are displayed, axial, coronal, sagittal (both left and right) or all pages
• "Show marks" - display location of named structures in original Talairach atlas (with green dots)
• "LUT center" - center of intensity Look Up Table (LUT) ramp for atlas pages, increasing makes image brighter
• "LUT width" - width of LUT ramp for atlas pages, decreasing adds contrast

Volume Display Options

• "Show grid" - display Taliarach grid
• "Show labels" - display sub-grid and grid labels
• "LUT center" - center of intensity Look Up Table (LUT) ramp for volume slices, increasing makes image brighter
• "LUT width" - width of LUT ramp for volume slices, decreasing adds contrast
