Abstract

PURPOSE:To obtain a good image having no ghost, by reversing the polarities of inclined magnetic fields respectively applied at the application times of a 90 deg.-pulse and a 180 deg.-pulse. CONSTITUTION:A 90 deg.-pulse and a 180 deg.-pulse having a specific frequency RF signal as a carrier are successively applied while a slice surface selecting inclined magnetic field is applied. The polarity of the inclined magnetic field applied along with the 90 deg.-pulse is made opposite to that of the inclined magnetic field applied as the 180 deg.-pulse.
