Defining contours

The ventricle contours serve as the basis for calculating the results of the analy-

sis. There are two ways of defining the contours for the end diastole and end sys-

tole: either manually or by drawing in the valve plane and the apex followed by

automatic contour detection.

You can also draw the wall contour to determine the data of the ventricle wall.

Automatic contour detection

Starting At the system console or at the touchscreen control

As soon as you have selected an ED or ES image, automatic contour detection is

activated.

– The mouse pointer changes shape to a square.

Aortic valve First define the position of the aortic valve with a line:

u Click on a point on the edge of (outside) the aortic valve in a line with the valve

plane.

u Click on a point on the opposite side of the aortic valve.

– The points marking the valve plane are indicated by squares.

Apex Now define the position of the apex:

u Click on the apex.

– This point is also indicated by a square.

– The contour is drawn.
