MAGNETIC RESONANCE SIGNAL RECEIVER AND MAGNETIC RESONANCE IMAGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance signal receiver for simplifying the constitution of a coil loop selecting means and a magnetic resonance imaging device using such a magnetic resonance signal receiver. SOLUTION: An active disabling circuit by a diode 228 and a passive disabling circuit by an inductor 232 connected in parallel to a capacitor 226 via a pair of antiparallel diodes 234, 234' are arranged in plural receiving coils 220 to 380 forming a phased array, and the active disabling circuit is controlled by a bias control means 120.
