Coil driving method, coil driving apparatus and MRI apparatus |
摘要 |
With the objective of preventing variations in sensitivity even if samples to be inserted between an upper coil and a lower coil opposite to each other are different in body frame, a pre-scan is effected on a sample in a state in which the sample is placed in a space defined between the upper coil and the lower coil, and reflected waves sent from the coils are detected by a directional coupler. Further, a comparison controller controls an attenuator so that the voltages of the reflected waves are equalized. Afterwards, a main scan is carried out.
