(Top) Isosurface of a phantom simulating a cross-section of an organelle with a set of proteins at random orientations. (Bottom) Tomographic reconstruction of the phantom at two different orientations. On the right image it can be seen that the organelle wall is very well defined along the tilt axis (vertical axis of this image) while there is a huge uncertainty along the perpendicular direction (horizontal axis of this image).
