Abstract
PURPOSE:To obtain accurate intracardiac dynamic pressure distribution, by operating intracardiac two-dimensional dynamic pressure distribution fro a speed component in a direction other than an ultrasonic beam emitting direction to display the same. CONSTITUTION:An ultrasonic burst wave is emitted from an ultrasonic probe 6 by the burst signal from a transmitter 5 and an intracardiac reflected wave is stored in a memory 2 through an A/D converter 8 and an input and output apparatus 4. Further, advection acceleration is calculated by operation to be stored in the memory 2 and a speed component is calculated on the basis of the advection acceleration and, further, dynamic pressure is operated. This dynamic pressure is stored in an image memory 11 to be displayed on a display apparatus 12.
