Generate a profile graph

About this task

Use these steps to generate a profile graph that shows the voxel value along a 3D trace (profile).

Step-by-step instructions

  1. Open the MR General Review.
  2. In one of the viewports, select a view type of Profile from the image type active annotation.
    • The view will display "Undefined profile" until you start to define the trace.
  3. To define a trace, from the viewport containing the image you want to use, press and hold Shift. Click to deposit points on the area of interest.
  4. On the resulting profile, click to display the voxel reference line (thin vertical line on the profile graph).
  5. Drag the voxel reference line to move the 3D cursor to the corresponding position on the trace.
    • The reference lines shows the voxel value at the position of the 3D cursor.
    • Mean (average voxel value along the trace) and Std. (standard deviation of voxel values along the trace) is displayed at the bottom.

      1. Voxel reference lineShows the voxel value at the position of the 3D cursor. Drag the voxel reference line to move the 3D cursor to the corresponding position on the trace.
      2. StatisticsThe statistical information about the voxel values along the trace is displayed at the bottom of the profile view. The Mean = average voxel value along the trace and Std. = standard deviation of voxel values along the trace.
