<P>PROBLEM TO BE SOLVED: To provide an ultrasonograph which displays appropriate waveforms without specifically being aware of an analysis mode when an ultrasonographer performs a blood-flow signal analysis and a tissue signal analysis. <P>SOLUTION: The ultrasonograph, equipped with a means (45) for optimizing a velocity range and a base line position by determining aliasing of a velocity from signal information on a Doppler spectrum out of received signals in a cardiovascular diagnostic region, is equipped with the changing and adjusting means (45) to change and adjust at least one out of transmitting and receiving conditions, a gain allocation, Wall Filter setting, a scroll speed, and a range gate size. <P>COPYRIGHT: (C)2007,JPO&INPIT |
