Abstract
A step of changing the frequency of a rotational field for nuclear magnetic resonance measurement of a medical nuclear magnetic resonance imaging apparatus is set to be smaller in a region of interest in a cross-section of an object to be examined than that in regions of less interest. In the less interesting regions of less interest, the spatial sampling interval is made large and an interpolating calculation is performed for the obtained projection data to provide data at the same spatial interval. The image reconstruction can be performed using an ordinary image reconstruction algorithm.
