To perform optimal alignment:
• Translate and tilt SAX plane so that it is aligned and just
above MV (on atrium side) in APLAX and MC views.
• In APLAX and MC views, translate and tilt the SAX plane so
that their intersection is in the center of MV.
• Adjust the center line in APLAX And MC so that their
intersection is in the center of MV.
MC, APLAX, and SAX are always orthogonal in all views.
The user must identify in the sequence the frames
corresponding to end-diastole (ED) and end-systole (ES). To
perform optimal alignment, rotate any of the views and move the
annulus plane.
1. ED and ES are automatically estimated and Set ED and Set
ES buttons can be used to modify and correctly mark ED
and ES frames.
2. To select another frame adjust the Frame control.
Set Landmarks
1. Select Set Landmarks.
The default screen displays two long axis views (MC and
APLAX) and short axis 3D view at the annulus plane aligned
according to surgical view (the 3D looking from atrium to MV
and with aortic valve on top) (Figure 8-37).
2. Place landmarks on: In MC view, mark the two mitral
annulus hinge points (MA1 and MA2); on APLAX view mark
the Posterior annulus hinge (P), Anterior annulus hinge (A),
Coaptation (Coap), and Right Sinus Aortic Annulus (Ao)
points.
3. When last landmark is placed segmentation is automatically
launched.
