Abstract

PURPOSE:To remove the strain of an image by the waveform of a gradient magnetic field at the time of high speed imaging, by reconstituting an image on the basis of the sampling data of a magnetic resonance signal obtained during a steady period except the periods of the rising and falling parts of a reading gradient magnetic field. CONSTITUTION:A static magnetic field magnet 1 and a gradient magnetic field forming coil 3 uniformly apply a static magnetic field and a gradient magnetic field to an object 5 to be examined. A high frequency magnetic field is further applied to the object 5 to be examined from a probe 7 under the control of a system controller 10 and the echo signal received by the probe 7 is sent to a computer 12 to be subjected to image reconstituting processing and displayed on an image display 14. The switching waveform of a reading gradient magnetic field generates waveform at rising and falling parts to become the strain of an image. The reconstitution of an image is performed only during a steady period except the rising and falling parts. As a result, a good reconstituted image having no strain is obtained.
