METHOD FOR OPTIMIZATION OF A MULTI-CHANNEL COIL

摘要

The invention relates to a method for optimization of the performance of a multi-channel coil (1) comprising at least three coil elements, wherein the method comprises the following steps: a) Exciting the coil elements of the multi-channel coil (1) by electrical power signals comprising a specific power, wherein the power of the power signals is partially reflected by the coil elements of the multi-channel coil (1), b) Measuring the power which is reflected by the individual coil elements of the multi-channel coil (1) or by the entire multi-channel coil (1) during excitation of the coil elements, c) Tuning the multi-channel coil (1) depending on the measured reflected power so that the performance of the multi-channel coil (1) is improved, wherein d) all coil elements of the multi-channel coil (1) are simultaneously excited, and e) the reflected power is measured during the simultaneous excitation of all coil elements of the multi-channel coil (1).
