发明名称 Ultra wide band wireless radio transmission in MRI systems involving channel estimation
摘要 At least one radio frequency coil (28, 30) is disposed within an examination region (14), the radio frequency coil (28, 30) wirelessly receives a spread spectrum calibration signal from and transmits multiple channels of data in spread spectrum data signals to an associated wireless transceiver (60, 64; 62, 66). A channel estimator (104, 106) estimates frequency dependent signal strength characteristics based on the calibration signal between the wireless transceiver (60, 64; 62, 66) and the associated coil (28, 30). A signal strength adjuster (108, 110) makes a frequency dependent adjustment to the data signals strengths such that the transmitted data signals are compensated based on the estimated signal characteristics from the received calibration signal to create frequency dependent compensated data signals.
