The invention relates to a method of determining at least one contour of a left
and/or right ventricle of a heart from at least one image of the heart, for example,
an image as acquired by means of MR imaging, in which there are determined start
parameters which are subsequently optimized by means of an iteration procedure
so as to form final parameters which define the contour, the iteration being carried
out with predetermined step sizes for the parameters as well as with a predetermined
number of steps, where in each iteration step and for each parameter setting individually:
- grey values of the image are determined at a predetermined side of the
contour so as to provide a first reference image;
- the first reference image is processed so as to form a second reference
image in which a uniform grey value which is derived from a grey value from the
first reference image is taken up at the predetermined side of the contour;
- the first and the second reference image are correlated so as to provide
a parameter correlation value and, when the latter correlation value has been improved
relative to the parameter correlation value associated with a preceding iteration
step, the parameters associated with the improved parameter correlation value are
selected as a basis for the next iteration step, the final iteration step yielding
the final parameters which define the contour.
