Abstract
A device provides simple positioning of the patient's head and simple positioning of the TMS coil relative to a coordinate system of the patient's head once the head is positioned. The TMS coil is fixed at a treatment position in the coordinate system of the patient's head and the position in the coordinate system is recorded for use in subsequent clinical sessions. A positioner assembly supports the weight of the TMS coil and allows the operator to freely move the TMS coil to search for the patient's motor threshold position (MTP) and/or the treatment position (TXP). If the TXP is in registration with the MTP, once the MTP is determined, the positioner assembly requires only a single adjustment of the magnet position to locate the TXP where the coil is locked in place for the duration of the TMS therapy. By recording the positions of the different adjustable components in the respective coordinate directions of the coordinate system of the patient's head, exact repositioning of the TMS coil for the patient during a subsequent clinical visit is made possible without use of expensive imaging equipment.
