MAGNETIC RESONANCE IMAGING DEVICE AND SYNCHRONOUS IMAGING METHOD

摘要

The time required for capturing an image in synchronization with cyclic body movement information relating to an examinee having a cyclic body movement can be reduced while maintaining a desired image contrast.  In a synchronous measurement of an echo signal synchronized with trigger information detected from the cyclic body movement information relating to the examinee, a first period is provided before the measurement period of the echo signal or a second period is provided after the measurement period of the echo signal.  A K-space is divided into a plurality of partial regions.  At least one of the first period and the second period is made different between the echo signal measurement corresponding to the partial region of the low spatial frequency side and the echo signal measurement corresponding to the partial region of the high spatial frequency side.
