The invention relates to the field of medical detection, and specifically relates to a
transcranial magnetic stimulation target positioning method. The method comprises the following steps: (1), obtaining a craniocerebral magnetic
resonance scanning image of a patient; (2), finding a nearest projection pint of an intracerebral to-be-stimulated region on head
skin from the image through calculationbased on the magnetic
resonance image, wherein the nearest projection pint is called as a head
skin target; (3), calculating the nearest distances between at least three mark points on the face of the patient and the head
skin target on the head
skin surface in the
image based on the magnetic
resonance image; (4), enabling a flexible rule to take each mark point as the circle center and take thedistance between each mark point and the head skin target as the
radius for drawing a circle on the head skin, wherein the intersection point of the circles is the head skin target. The method mainlydepends on the calculation of the cambered
surface distance of each mark point on the transcranial magnetic resonance image, so the method is simple and convenient, does not need large-scale equipment, and exerts low requirements for a treatment place. Moreover, compared with a
navigation system, the method greatly reduces the cost.
