In situation where the field of view of a particular magnification do not permit

designed for minimum interaction with the user. Once the initial ROI is
positioned correctly, click either the right mouse button or the OK button to
start. The system moves along the respective leads sector performing a series
of stations so that enough overlap gets seen. As the system moves along the
sector, the user is prompted to select Ok or Cancel, to continue press Ok, to
stop press Cancel.
