ABSTRACT:
In a multiple coil type magnetic resonance imaging system, MR signals can be obtained at high S/N ratio and over a large image region. The magnetic resonance imaging system includes: a plurality of receiving coils for receiving a plurality of MR signals generated from plural portions of an object under medical examination; a plurality of filters coupled to the plural receiving coils, for filtering the plurality of MR signals to obtain a plurality of filtered MR signals; a processor and a filter passband setting circuit for setting passbands of the plurality of filters in such a manner that the plurality of filtered MR signals have preselected frequency bands different from each other; and, an adder for adding the filtered MR signals with each other which are derived from the filters coupled to at least two receiving coils selected from the plurality of receiving coils.
