Magnetic resonance imaging device and magnetic susceptibility emphasis picture photographing method

摘要

The magnetic susceptibility emphasis picture whose signal noise ratio is good at the time of magnetic susceptibility emphasis photographing which uses the ekopurena method in the MRI device, is obtained. Impressing the phase blip inclined magnetic field, reversing the polarity of the frequency encoding inclined magnetic field, the occasion where it measures the plural echo signals, dividing the plural echo signals with into the 1st echo signal group and the 2nd echo signal group, from the 1st echo signal group the graphics data, acquiring the aforementioned mask data, respectively from the 2nd echo signal group, from the graphics data and the mask data you acquire the magnetic susceptibility emphasis picture.
