Method for identifying stimulation target

A method for identifying a boundary of a stimulation target, comprising the steps of:

• (1) performing Computed Tomography (CT) scanning and Magnetic Resonance Imaging (MRI) on a specific region inside a patient to obtain a first implantation trajectory for the specific region;
• (2) arranging a plurality of electrodes on each of a plurality of composite probes, and implanting the plurality of composite probes into the specific region based on the first implantation trajectory to obtain microelectrode recording signals via the plurality of composite probes, thereby enabling the plurality of composite probes to be guided into predefined depths within the stimulation target of the patient based on the microelectrode recording signals;
• (3) enabling the electrodes arranged on each of the plurality of composite probes to inject a plurality of electrical currents into tissue structures surrounding the plurality of composite probes and using the plurality of composite probes to measure a plurality of electrical potentials, and converting the plurality of electrical potentials into a plurality of images that delineate the tissue structures surrounding the electrodes arranged on each of the composite probes, wherein one of the plurality of electrical potentials is measured for the tissue structures surrounding the plurality of composite probes by enabling one of the plurality of composite probes to shift forward or backward along the first implantation trajectory at a predetermined distance;
• (4) reconstructing an image, position or shape of the stimulation target according to discrete data by measuring discrete values from the electrodes and a plurality of independent boundary measurements of the electrodes;
• and
• (5) identifying the boundary of the stimulation target and pin-pointing locations of the composite probes implanted within or outside the stimulation target according to the plurality of images.
