BOLDfonic fMRI audio (6)
Will you be able to modify/drill my penetration panel to allow for the two BNC connectors to mount during installation of the equipment?
No. We are not equipped to perform this as it requires facilities approval. You should consult the manufacturer of the penetration panel as well as your facilities department for proper guidance.
Typically it is not suggested to run the cabling overhead towards the MR scanner as there is potential of coupling with the RF cables of the scanner. If the aim is to reduce stray cabling along the floor it is suggested that the headphones are stored/hung with excess fiber cabling “looped” as to keep it out of the way.
I noticed that the standard setup does not include a patient microphone; is there one available for bi-directional communication?
Yes! While not included as standard there is an option for an Optoaccoustics patient microphone available in both basic and noise canceling models. Please request pricing if interested!
Yes! There are headphones that span the full range of infants through adults. Additionally there are insert (air-tube) earphones that can be used for all ages, and for all headcoils.
Shielded BNC cables are routed through a filter box/transformer. The supplied BNC connectors will need to be mounted within your penetration panel, this will require two 11mm holes for this purpose, the supplied RF filters will be connected on the MR side with 9 meters of cabling to connect to the headphones. Typically cables run from the penetration panel located between the control room and scan room, however extending the BNC cabling may also be possible to route it from the equipment room.
The BOLDfonic system is comprised of the MR Confon main console, an operator microphone, a set of patient/participant insert earphones, control room monitoring speakers, along with all audio cables, connectors, and filters necessary for full installation — just supply the audio output from your PC or alternative source via a ⅛ in. audio cable or SPDIF output. Keep in mind that the BOLDfonic system includes the AudioFile unit which can function as an external USB audio card.
