ABSTRACT:
A sequence for detecting variations in the blood flow speed in the blood vessel is added before a measurement of imaging signals so as to determine the highest and/or the lowest speed points of time and an examined body is imaged two times at those timings. In this way the timing for setting the delay time measured from the R wave can be determined automatically and thus it is possible to obtain a blood vessel image of high quality in a short time with the minimum number of two images.
