One of the described methods includes: examining a worklist which schedules at least one modality to perform at least one task; and ensuring that in the faster access part there is available at least some data which based on at least one predetermined rule is deemed likely to be accessed in connection to the at least one task to be performed by the at least one modality scheduled by the worklist.
