For your first TMS session, the doctor will explain the entire procedure and answer any questions or concerns you may have. Your skull will be measured to find the exact location in your brain where the treatment should be targeted. In order to receive the correct dosage of the treatment every time, correct positioning and maintaining continuous direct contact between your skull and the coil is necessary. Neurostar uses 3-D laser positioning that precisely determines and saves your information so your subsequent visits will go faster. The TrakStar™ Cloud will store your position and dosage information so your treatment is accurate every time.
