There are three positioning modes that are defined at the “Program” level: • In normal scenarios the configuration in the Dot Cockpit is sufficient and the user should not worry at all about the table positioning modes when executing a MR examination. • ISO: The table moves systematically so as to place the center of volume of the sections to be acquired at the isocenter. • LOC: A “solid gray triangle” marks the table zero on the left-hand side of the image in the positioning segment, halfway up. The table does not move, except in the event of the manual modification of the zero, or significant displacement of the center of volume of the ARH sections to be acquired. • FIX: The table remains fixed at the position defined as zero.

All adjustments (shim) must be repeated each time the table is moved. • Using the FIX mode is reserved for interventions.

However, acquisition remains possible. • In LOC mode, such a situation may also arise. In this case, ISO mode will be automatically activated. • In the Right–Left and Anterior–Posterior directions, this warning may appear. However, acquisition remains possible.
