摘要： Provided are a multi-channel encoding and decoding method and apparatus capable of encoding and decoding residual signal by removing redundant information between a plurality of channels without a downmixed signal. In the method and apparatus, a reference signal which is to be used for encoding from a plurality of channel signals, the phase differences between the respective channel signals and the reference signal, gains which are the ratios of the amplitudes of the respective channel signals to the amplitude of the reference signal, and residual signals which correspond to differences between predicted signals and the actual channel signals, are encoded or decoded. The predicted signals are obtained by applying the phase differences and gains to the reference signal.

摘要： In a magnetic resonance imaging apparatus being medical diagnostic equipment for understanding the internal structure of a human body, a radio frequency coil for a magnetic resonance imaging apparatus is provided for transmitting and receiving a magnetic resonance signal for forming a magnetic resonance image of a portion of a human body. The coil has an opening formed by splitting a portion of one turn of the coil into two. Thereby, a radio frequency coil for a vertical magnetic field provides a maximum open area. Therefore, a simple operation or an observation can be made through the opening simultaneously with taking a magnetic resonance image of the affected part. Also, a patient can feel less claustrophobic because they can see out through the opening.
