Title:
磁気共鳴撮影装置
Document Type and Number:
Japanese Patent JP4575579
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus which can set a driving power for cooling for every protocol with different number of times for repeating pulse sequences in one repetition time, or one TR, can prevent from producing images out of focus, and reduces power consumption and noise. SOLUTION: A magnetic resonance imaging apparatus is equipped with the following parts: A control section 25 refers to a look-up table or computes automatically and produces a controlling signal CTL1 which directs to cool down a radio frequency coil, or a RF coil, 214 for every protocol with the most appropriate cooling capacity by a cooling system 40 without cooling it excessively when a data processing section 31 of an operator console 30 appoints a protocol to carry out. A cooling system 40 leads cooling air to a passage 41 for cooling air connected to the RF coil 214 with a cooling capacity which meets the direction of the controlling signals CTL1 by the control section 25.
