Fantoma multicanal of magnetic dipolos orientables for magnetoencefalografia (Machine-translation by Google Translate, not legally binding)

摘要

Multichannel fantoma of magnetic dipoles orientable for magnetoencephalography, comprising: - a simulated head (1), divided into horizontal portions (5), with a hole (3) for guiding cables that excite the magnetic field generators (9) and housings (2) to accommodate the screws for fixing the horizontal portions (5), these having holes (7) for fixing the generators (9); - a generator (9) for each channel of the phantom, comprising three coils (10a, 10b, 10c) on a support (11) in coordinate directions (z, y, x), with a lower stem (12) that starts from the support (11) for its fixing in a hole (7) of a horizontal portion (5), each of the coils (10a, 10b, 10c) being driven by an excitation current signal (bz (t), by (t), bx (t)), producing the coil (10a) opposite the lower stem (12) the vertical component z of the magnetic dipole, and producing the other two coils (10b, 10c) the components (x, y) in the plane of the horizontal portion (5).
