How to obtain an optimal 3D US coronal plane: tomographic ultrasound imaging (TUI) is the representation by a series of parallel slices through the volume and the distance between the slices as well as their number can be configured; the plane is optimal only if the slices or cutting line is exactly on the endometrium and the junctional zone at the level of the tubal ostia and isthmus (a) at the central plane
