MAGNETIC FIELD SOURCE MOVABLE PHANTOM HEAD |
摘要 |
A magnetic field source movable type phantom head has a vessel filled with physiologic saline. The vessel preferably has an inner contour corresponding to an outer contour of a cerebrum of a patient to be tested. An electrode support tube has electrodes at one end. The electrodes are arranged within the vessel and movable at least in a vertical direction toward a center of the vessel as guided by a guiding and fixing device which guides the electrode support tube in a liquid tight fashion and fixes at a predetermined position. A position of the electrode support tube is measured to determine a position of the magnetic field source in the vessel.
