All spheres are always displayed in the MIP window. The line of the intersection of the sphere with the image plane and the measurement results are displayed in the other windows. As the distance from the center of the sphere increases, the diameter of this circle decreases. If the sphere does not intersect with the image plane, the measurement results for the sphere are not displayed in this window.
If the center of the sphere is in the current image and the VOI Sphere tool is activated,
crosses are displayed in the center of the sphere and on its border.
