A medical imaging device and method having a display screen, a processor
for processing image data in order to display the data in the form of a
3D model, and a user interface. The processor acquires at least two
points positioned in the 3D model via the user interface; deduces the
positioning of an axis defined by the two points in the 3D model, and
reorients the 3D model in such a manner that the axis as indicated in
this way is to be found in a predefined orientation relative to the plane
of the display screen.
