About This Product

The world's first ANC (Active Noise Control) thin headphones developed using new technology (patented). MRI/audio auditory stimulus presentation OptoACTIVE device. This device has received high praise both domestically and internationally as an MRI brain research device. FOMR1-III is used on the MRI side to achieve high quality audio for simultaneous two-way communication (MRI noise cancellation method).

■LCD touch control box

All operations are displayed on the LCD, and it is equipped with various adjustment knobs, audio speakers, audio transmission PTT, input terminals, output terminals, etc.

■ANC noise canceling headphones

MRI noise is canceled by ANC, allowing you to receive good auditory stimulation signals, voices, and music with high-quality headphones.

■Control room monitor speaker

The operation control box installed in the operation room uses FOMRI-Ⅲ (Dual Channel optical microphone) to cancel the MRI noise using ANC technology and output the subject's voice.

■Audio signals are managed using TTL

The output audio signal is managed by TTL, so it can be synchronized with the fMRI image. The noise cancellation status inside the headphones can be monitored on the LCD control box (liquid crystal touch panel screen) installed in the control room. All communication control is performed by EOU (Electro-Optical Unit). The operator's voice can be communicated two-way with the MRI subject using the microphone in the LCD control. Compatible MRI: GE, Siemens, Philips, Canon, Hitachi, and others The optional Eapad Cover improves the adhesion accuracy of optical headphones and improves MRI noise reduction performance. Additionally, Air Multipad absorbs vibrations from the head coil inside the gantry, stabilizes the optical headphone, and improves MRI images. You can see the operation of the ANC Active Noise cancellaton Headphone on the LCD display.

■ANC frequency characteristics

It reduces the noise inside the headphones by 25 to 30 dB and provides high quality auditory presentation signals, voices, and music.
