Abstract:
An inspection apparatus using magnetic resonance comprising: means for generating a static magnetic field; means for applying a gradient magnetic field which applies a static magnetic field gradient; means for applying a high frequency magnetic field to an object to be inspected; and means for detecting an echo as a magnetic resonance signal from the object of inspection, wherein there is provided control means for controlling the means for applying the gradient magnetic field and the means for applying the high frequency magnetic field, and the control means has a sequence for controlling the gradient magnetic field applying means and the high frequency magnetic field applying means to generate an echo, applying a phase-encoding gradient magnetic field quantity, and measuring the echo and has a step of storing a body movement signal outputted from body movement measuring means which measures movement of the object of inspection to memory means and performing the sequence a plurality of times with the same phase-encoding gradient magnetic field quantity while the sequence is performed, repeatedly performs the step while varying the phase-encoding gradient magnetic field quantity, and increases the number of execution times of the sequence in the step when an absolute value of the phase-encoding gradient magnetic field quantity is small as compared to a case where an absolute value of the phase-encoding gradient magnetic field quantity is large.
