Abstract:
1. A magnetic resonance imaging apparatus comprising: object placing means for placing an object to be examined in an imaging space; translating means for translating the object placing means on which the object is placed in a given direction continuously or step-wise; magnetic field generating means which is to be placed around the imaging space, and exciting the desired position of the object by generating a static magnetic field, gradient magnetic field and a high-frequency magnetic field in the imaging space; signal detecting means to be placed around the imaging space, and for detecting a magnetic resonance signal generated from the object; signal processing means for performing signal processing on the magnetic resonance signal detected by the signal detecting means, and constructing a magnetic resonance image of the object; and control means for controlling the translating means, the magnetic field generating means, the signal detecting means and the signal processing means, so as to obtain a magnetic resonance image of the object while translating the object continuously or step-wise to a predetermined position at predetermined speed, characterized in further comprising: translation error detecting means for detecting an error of the position or the set value of the speed; and correcting means for correcting the error detected by the translation error detecting means.
