MAGNETIC RESONANCE IMAGING DEVICE AND CONTROL DEVICE THEREOF

WIPO Patent Application WO/2012/173095

A1

A control device (30) of an MRI device (20A) comprises a condition setting unit (100) and an assessment unit (102). The condition setting unit (100) sets an image capture sequence on the basis of a condition of an image capture sequence which is executed with the MRI device. The assessment unit (102) computes, on the basis of the image capture sequence condition, an electrical current value which is supplied to a gradient magnetic field coil (26) of the MRI device (20A), computes, on the basis of mutual inductance in which the gradient magnetic field coil (26) generates mutual inductance, a voltage value to be applied to the gradient magnetic field coil (26) so as to apply the electrical current value, and assesses whether to execute the image capture sequence prior to the execution of the image capture sequence, on the basis of the voltage value.
