Abstract (en)
[origin: WO0119427A2] A distributed architecture for adapting apparatus for use in a high magnetic field and/or intense RF environment. In one embodiment, an advanced ventilator is adapted to be MRI-compatible by creating a mechanical and electrical separation between the functional elements of the ventilator with only a minimum ensemble of electronics remaining near the MRI coil. Local components of the ventilator that must be close to the MRI are positioned accordingly. These items will typically include the ventilator control panel, the status display, and the breathing bellows. Remote components that are sensitive to magnetic and/or RF fields or may adversely impact the MRI image are placed away from the immediate influence of the MRI. These devices will typically include the control processor, monitoring sensors, and proportional gas control solenoids.
