A magnetic resonance imaging apparatus generates an MR signal from an object by applying a gradient field pulse generated by a gradient field coil and a high-frequency magnetic field pulse generated by a high-frequency coil to the object in a static field, and reconstructs an image on the basis of the MR signal. The gradient field coil is housed in a sealed vessel. The internal air in the sealed vessel is exhausted by the pump to prevent noise. By controlling the operation of the pump using a control circuit, noise in imaging operation can be reduced more effectively.

Magnetic resonance imaging apparatus

A magnetic resonance imaging apparatus comprises a collecting section that collects from the subject the magnetic resonance signals corresponding to N phase encode data items for restructuring each of a plurality of images, a restructuring section that restructures each set of N phase encode data items corresponding to the magnetic resonance signals obtained by the collecting section, an image processing section that processes the restructured images obtained at the restructuring section, an image output section that outputs the processed images obtained at the image processing section, and a changing section that changes the number of phase encode data items updated among the N phase encode data items restructured at the restructuring section, while the collecting section is in operation.
