6. eneral questions regarding the MRI kit For questions related to a specific component manufactured by BIOPAC Systems Inc we recommend you to contact the original manufacturer Neuroelectrics Barcelona SLU BIOPAC Systems Inc US Corporate Offices Avinguda Tibidabo 47 bis 43 Aero Camino Goleta 08035 Barcelona Spain CA 93117 USA Telephone 34 93 254 03 70 Telephone 1 805 685 0066 neuroelectrics SAFETY WARNINGS WARNING The installation of the MRI kits is recommended to be handled by personnel specialized in shielding systems WARNING Place the stimulation electrodes ONLY on the head of the subject Never place the stimulation electrodes so stimulation currents are permitted to flow through the subject s heart WARNING Correct installation of the MRI Filter is required to maintain MRI imaging performance preserve physiological recording quality and create a safe operating environment WARNING Correct installation of the the Patch Panel is required Radio frequency RF energy generated by MRI travel through a poorly implemented patch panel and affect the stimulator function The Patch Panel filtering and cabling must have a very low impedance to MRI ground less than 1Q at 42 T MHz where T is the Tesla strenght of MRI For a MRI this means the patch panel should have less than a 1 2 impedance to MRI main ground at 128 1 MHz The Filter must be installed on the Patch Panel in order
7. erface between the MRI Chamber and the Control Room Commonly MRI facilities are al ready equipped with a patch panel which is incorporated in the wall between the chamber and the control room For that reason the patch panel is not included with the MRI kits Neuroelectrics may produce a customized patch panel with slots to insert the MRI Filter s upon request This item is sold separately MRI ADAPTER DB9m CABLE a 7 The DB9 male male cable is used to connect e the MRI Fitter to the MRI ADAPTER T The MRI ApAPTER connects up to two DB9m cables to the Starstim tCS TESTBOARD CABLE The TESTBOARD CABLE connects the MRI Apapter to the STARSTIM tCS NEcBox It is included in the STARSTIM and STARSTIM tCS packages but not in the MRI kits Nevertheless this cable is required when STARSTIM Or STARSTIM tCS are used with the MRI kits This item can be also sold separately 111 INSTALLATION When STARSTIM or STARSTIM tCS are used during MRI experiment it is essential that all the equipment is correctly installed The installation of the MRI Kits are recommended to be handled by personnel specialized in shielding systems The Fitter and PATCH PANEL interface require special attention when installed Always make sure that the PATCH PANEL Is properly connected to the ground of the MRI A metallic L bracket structure supports the MRI FILTER The L bracket Is attached to the PATCH PANEL using a pair of s
8. les It is the ideal solution for cathodal or anodal stimulation sessions The multi channel kit takes STARSTIM tCS to the next level With this kit all the eight channels of the device can be used for stimulation inside the MRI room The reduced size of the eight sponge electrodes provided allows multi focal stimulation experiments and ensures a high spatial resolution of the target area In addition two standard sponge electrodes are also part of the kit for eventual bipolar studies Note that the MRI compatible kits are intended to be used for stimulation Do not use them for EEG recording Before using the kit read the NEUROELECTRICS User Manual Starstim ELECTRODES and Nic parts neuroelectrics Intended Use The intended use 16 stimulation during MRI for research purposes CAUTION Proper installation of the MRI filter is required Using the MRI kits without a correct installation of the filter is dangerous Read pages 10 to 12 to know how to correctly install the equipment Regulatory Information The MRI kits are intended to be used exclusively for clinical investigation CAUTION Investigational device to be used by Qualified Investigators only Manufacturer The MRI kits are prepared and commercialized by Neuroelectrics Some of the contents are manufactured by Neuroelectrics There are a few items properly identified in this manual that are originally manufactured by BIOPAC Systems Inc Contact Neuroelectrics office for g
