Abstract
A magnetic-resonance imaging apparatus of an embodiment includes a gradient coil, a transmitter coil, and a processing circuitry. The gradient coil applies a gradient magnetic field to an imaging space in which a subject is placed. The transmitter coil applies a RF (radio frequency) pulse to the imaging space. The processing circuitry calculates a target temperature of the gradient coil throughout multiple protocols to be executed in an examination of the subject, and controls a temperature of the gradient coil to approach the target temperature when a data used to set a center frequency of the RF pulse is measured.

A magnetic-resonance imaging apparatus, comprising:
- a gradient coil configured to apply a gradient magnetic field to an imaging space in which a subject is placed;
- a transmitter coil configured to apply a RF (radio frequency) pulse to the imaging space;
- and
- processing circuitry configured to calculate a target temperature of the gradient coil throughout a plurality of protocols to be executed in an examination of the subject, control a temperature of the gradient coil to approach the target temperature when data used to set a center frequency of the RF pulse is measured, generate image data based on MR signal data acquired by executing the plurality of protocols, and display an image based on the generated image data on a display.
