of u03b4t from that state the fat spectrum spf emerge as an imaginary part as indicated by the solid line in fig6 at u03b4t gt 0 since the magnetic resonance signals of the water and fat are inverted in their sign the sign of the fat image is inverted upon the reconstruction of an image when adjustment is made to be set to u03b4t 0 the water and fat separated signal is obtained with the same sign the water fat separated image thus obtained may be displayed individually independently or as a water fat combined image in this case the position of the water fat image is displaced due to a difference in their resonance frequency and that image is reconstructed after being adjusted properly at this time the images of the water and fat may be displayed in a different color the value u03b4t for imparting a phase difference to the magnetic resonance signals of the nuclei of h in the water and fat need not necessarily be adjusted by the 180 u00b0 pulse and may be obtained simply adjusting the data pick up timing that is the read out gradient field encode gradient field and data acquisition timing or selective excitation pulse the sequence for picking up the magnetic resonance echo may not be obtained from the echo planar method and may be any sequence so long as it is a sequence for ultra high.
