Abstract
A magnetic resonance imaging system has an excitation section, a signal collecting section, a first image processor, a maximum value detector, a threshold setting section, and a second image processor. The excitation section applies predetermined magnetic fields to a patient to excite a magnetic resonance phenomenon therein. The signal collecting section collects magnetic resonance signals produced by the magnetic resonance phenomenon. The first image processor obtains original image pixel data representing the distribution of magnetic resonance data, from the magnetic resonance signals. The maximum value detector detects the maximum amplitude value in original image pixel data. The threshold setting section sets a threshold value in accordance with the maximum amplitude value. The second image processor performs predetermined arithmetic processing using original image pixel data having an amplitude exceeding the threshold value, to thereby obtain processed image data from the original image pixel data.
