Manual tracking of
the sample area
(dynamic
anchored sample
area)
1. Place a sample area over a region of interest. Note the
anatomical location of the sample area.
2. Scroll to a new frame using the Trackball.
3. Press Scan Area until the QA trackball assignment is
selected.
4. Move the cursor to the sample area using the Trackball.
5. Press Set. The sample area is unanchored.
6. Drag the sample area to the corresponding anatomical
location in the new frame.
When the sample area is anchored in more than one frame,
linear interpolation is performed so that the sample area is
smoothly moved between the anchored positions in the
selected frames when running the cineloop.
7. Press Scan Area until the scroll trackball assignment is
selected.
8. Using the Trackball, scroll through the cineloop and control
that the sample area follows the moving anatomical
structure.
9. Add anchored sample areas in several frames to obtain a
more accurate displacement of the sample area.
