Abstract
This multipurpose, modular system provides diagnostic-quality, wireless, multichannel monitoring in diverse settings, including interventional procedures guided by X-ray and MRI, with variable electromagnetic interference (EMI) and eliminates the need for multiple detachments/reattachments of patient cables when the patient is moved from one room/procedure to another. The system includes: 1) multiple filterbanks (filtering procedures) for recording both diagnostic-quality (broad-band) signals in the absence of EMI and narrow-band signals in the presence of EMI, with subsequent reconstruction of diagnostic-quality signals from the narrow-band signals; 2) filtering of EMI, using a priori and adaptive criteria about differences between the EMI and physiological signals' characteristics; 3) filtering of the magneto-hydrodynamic effect, using physiological measurements at different distances from the magnet (i.e., at different strengths of magnetic field) and changes in blood flow and blood pressure; and 4) multiple wireless transmitters for increasing reliability and speed (throughput) of the wireless data transmission.
