The invention relates to a medical system, in particular a medical device, for planning and/or tuning a neuromodulation therapy, the system comprising:- a database means for storing a plurality of data sets, each data set comprising- meta data, e.g. patient data, in particular relating to gender data, age data, local field recordings data, microelectrode recordings data, tissue fiber structures data, demographics data and/or anatomy data of a patient, and- spatial data relating to the distribution of a stimulation field (70) of a neuromodulation probe (21)；- input means for entering at least one filter criterion；- filter means for applying the at least one filter criterion on the plurality of data sets to generate a filtered subset of the data sets；- merging means for merging the spatial data of the filtered subset to generate a functional data set；- visualization means for computing a three dimensional model (50) of the functional data set and for visualizing an image of the three dimensional model (50).The invention further relates to a method for planning and/or tuning a neuromodulation therapy.
