Your Price: $1,995.00

Audio is sent into the scan room through the RF penetration panel, and connects to the Patient Acoustic Interface by way of two BNC connectors The transducers white acrylic box has 2 internal transducers which convert the electronic signals into air driven audio Patients inside the MRI scanner magnet bore tube use acoustic headphones that are made completely from plastic materials- The plastic material will not be attracted to the high magnetic fields - Additionally, the plastic materials will not be visible in the MRI scanned images This Transducer is included with each of the Scan Sound MRI Sound System Kits

Patient Acoustic Interface - Transducer

The type of music selected by the technologist is usually based on the patient's music preferences
The audio goes from an amplifier near the operator console to a connector panel (RF penetration panel) in the computer room
Coaxial cables carry the audio from the connector panel down to the patient acoustic interface in the scan room
The coaxial cables connect to two BNC connectors going into the patient acoustic interface
The PAI is typically positioned on the floor near the base of the table at the front of the magnet
The electronic audio is converted to pneumatic sound and driven through twin vinyl tubes going to the patient headphones
MRI systems can not use wired headphones because electronic headphones might distort the images or cause detrimental artifacts
Conventional earphones and headphones operate using a magnetic field to move a small diaphragm to produce sound, and it is unlikely that those kinds of headphones could function inside the very high magnetic fields of the MRI system
That is why MRI headphones made completely from plastic materials must be used inside of the MRI scanner
The patient acoustic interface box is what we use to convert the electronic audio to air-driven sound
The PAI design delivers phenomenal sound from two specially made transducers located inside the acrylic box
The patients hear true stereo sound and that sound separation imparts a feeling of spaciousness that helps patients overcome claustrophobia

NOTE: Music systems with Mono sound from only one audio channel may not help to overcome claustrophobia

We recommend keeping the vinyl tubing from the PAI to the headphones as short as possible to deliver the best sound quality
The patient acoustic interface (PAI) is positioned in the scan room on the floor near the front of the MRI magnet
The acoustic headphones that are compatible with our PAI are all available on the Magmedix web site
Each of our acoustic headphones have twin barbed modular plugs that plug into two 1/4 inch ID vinyl tubes
The vinyl tubing connected to the PAI dimensions are ³/₈ inch OD and ¹/₄ inch ID
PAI Dimensions: 12 ⁵/₈ x 6 x 6 inches
Weight: 15 lbs
Impedance: 8 ohms per channel
