PROBLEM TO BE SOLVED: To commonly use a reception system in an MRI instrument with every magnetostatic strength. SOLUTION: The instrument includes: a means 25 for originating two high-frequency signals which are transmitted to the reception system from the inner part of a transmission system, and have a phase difference ofπ/2; and mixers 23a, 23b for converting the frequencies of two reception signals from two conductive loops respectively by the use of the two high-frequency signals.
