Summary:PURPOSE:To facilitate high highly precise regulation of bipolar gradient by applying bipolar gradient so that the polarity is reversed every line, and collecting repeated data. CONSTITUTION:In a pulse sequence of one repeat period, RF signal is successively applied as one 90 deg.-pulse and two 180 deg.-pulse. After the second 180 deg.-pulse, a phase encoding Gy pulse 3 is given, and A/D converting sampling pulse is generated for the data sampling of spin echoes generated thereafter. After the first 180 deg.-pulse and before the second 180 deg.-pulse, pulses 1, 2 of bipolar gradient are given. The pulses 1, 2 are reversed only in polarity and coincident in wave height value. The polarities of the pulses 1, 2, of bipolar gradient are reversed every line.
