Abstract

The invention relates to a system for planning and/or tuning a neuromodulation therapy, comprising:

• • a database means for storing a plurality of data sets, each data set comprising:
    • metadata 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 distribution of a stimulation field of a neuromodulation probe;
  • 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; and
  • visualization means for computing a three dimensional model of the functional data set and for visualizing an image of the three dimensional model.

Claims

1. A medical system, 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;

metadata 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 distribution of a stimulation field of a neuromodulation probe;

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; and

visualization means for computing a three dimensional model of the functional data set and for visualizing an image of the three dimensional model.

2. The medical system according to claim 1, wherein the merging means are adapted to calculate an average score of each data value of the filtered subset which is assigned to the same location in the main grid.

3. The medical system according to claim 2, further comprising registration means for mapping the three dimensional model of the functional data set on at least one patient-specific medical image, whereby the visualization means is adapted to visualize an image of the three dimensional model together with the patient-specific medical image.

4. The medical system according to claim 2, wherein the spatial data is represented by a matrix.

6. The medical system according claim 1, wherein the filter means is adapted to receive at least one Boolean expression related to the metadata, whereby the filtered subset of data sets is generated at least partially based on the Boolean expression.

7. The medical system according to claim 1, further comprising a simulation means for simulating a stimulation field of the neuromodulation probe, wherein the visualization means is adapted to visualize the stimulation field in relation to the three dimensional model of the functional data set.

5. The medical system according to claim 5, wherein for each point in the main grid, the distance from that point to each of its immediate neighbor points is not exceeding 1 mm.

8. A method for planning and/or tuning a neuromodulation therapy, the method comprising:

storing a plurality of data sets, each data set comprising;

metadata, 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 a distribution of a stimulation field of a neuromodulation probe;

entering at least one filter criterion;

applying the at least one filter criterion on the plurality of data sets to generate a filtered subset of the data sets;

merging spatial data of the filtered subset to generate a functional data set;

computing a three dimensional model of the functional data set; and

visualizing an image of the three dimensional model.
