BOLDfonic MR compatible Audio/Communication System.
Includes one set of headphones, amplifier, filters, desktop microphone for the technologist, a pair of monitor speakers, Lindy ADC, and all necessary cables.
Available headphones: HP VS 03, HP M 01, HP AT 01, HP PI US.
Hi-Fidelity MR compatible audio system coupled with a novel USB audio processor providing automated synchronous triggering capabilities offers an excellent solution for both clinical and research environments.
Modular audio uni and optional bi-directional communication solution helps participants cope with MRI-related acoustic noise and also can be used to deliver calibrated auditory stimuli for fMRI
Versatile control over auditory stimulus presentations, and the the flexibility to choose from various headphone designs, microphones, and bespoke amplifiers.
The circumaural, closed-back headphone is available in a number of sizes and cable routing arrangements to suit different headcoil designs. It offers superior gradient noise dampening compared to simple pneumatic, air tube solutions. Where space permits, soft, memory foam cushions can be inserted between the head and contact points of the coil to provide even better isolation, reduce bone conduction and improve patient comfort.
A unique electro-dynamic driver uses the magnetic field of the MRI scanner to drive the headphone membrane. This results in powerful speakers with an excellent frequency response across a wide range. An additional piezoelectric driver can be fitted to some designs, which enables those headphones to be used outside the bore too.
Bespoke stereo amplifiers are perfectly matched to the filter set and headphones; all designs have digital optical inputs to connect the signal source. They are easy to operate for routine clinical use, yet still offer sufficient flexibility and control of auditory stimuli for fMRI. The comprehensive BOLDfonic design can drive two headphones, external speakers, and supports a participant microphone. The novel AudioFile processor incorporated within the BOLDfonic system offers a digital and analog IO for trigger synchronization among devices and a mode for precise TTL controlled stimulus delivery. Of course audio output can also be controlled from a computer.
A compact scanner operator microphone sited in the console room can be combined with an Optoacoustics noise-cancelling version mounted to the headphone to provide clear, simultaneous, bidirectional communication.
Several headphone options exist, and these options determine the final price of the system. *** Note: Unless you have a quotation that identifies the configuration as being suitable for your particular scanner make/model, the quoted price may or may not represent the cost for a suitable configuration for you. ***
