<p>PURPOSE:To provide a satisfactory blood vessel image having no unevenness while keeping a short measuring period without increasing the imaging time. CONSTITUTION:A pulse sequencer for sending a blood flow to a sequencer is provided. In the measurement of the pulse sequencer, only the first echo signal measurement of an imaging target slice is synchronized with an electrocardiogram, and the measurement repeated thereafter with the same slice is conducted according to a repeating time set non-synchronously to all the electrocardiograms. Thus, the signal strength of blood flow is nearly uniformized between each slice without being affected by the heartbeat, and the two- dimensional projected blood vessel image can be also obtained as a uniform image.</p> |
