Chapter 48: Analyzing Contrast Mode images
5. Click on the boundary of the inner wall of the myocardium, add caliper points
using the same procedure you used to create the outer wall contour, and then
right-click to complete the inner wall contour.
The system adds the measurement label on the image and adds the
measurement to the Measured Values section at the bottom of the left panel.
6. If you need to move the entire measurement, click on a measurement line and
then drag and drop it.
f To automatically apply cardiac region contours to sequential frames
in a cine loop:
1. On the cine loop, move to a frame that displays the maximum point of
diastole and create the outer and inner contours for a single cardiac region
measurement as described above.
IMPORTANT: To ensure the best results with the sequential refinement process,
add your first three caliper points for every contour in the same direction. For
example if you start out adding your first three points for the outer wall in a
clockwise direction, add your points for the inner wall in a clockwise direction also.
2. In your cine loop, move forward or backward to a frame that displays the next
point of maximum systole and create a second cardiac region measurement.
IMPORTANT: Add your first three caliper points for these contours in the same
direction you added the contours for the first cardiac region.
3. Right-click the contour and then select Replicate Forward 1 Cycle or
Replicate Reverse 1 Cycle.
The system:
a. Calculates and creates cardiac region contours for the half-cardiac cycle
frames between the maximum diastole and systole points you measured.
b. Plays the cine loop forward or reverse and applies the calculated contours
to each individual frame.
Direction Description
Replicate Forward 1 Cycle
Starts from the end of your half cardiac cycle and applies the
system-calculated contours to the next cardiac cycle.
Replicate Reverse 1 Cycle
Starts from the start of your half cardiac cycle and applies the
system-calculated contours to the previous cardiac cycle.
4. If you want to modify a contour in the sequence, you can add, delete or move
points and then right-click Refine Forward or Refine Reverse on your
contour to view the results.
