<P>PROBLEM TO BE SOLVED: To provide an ultrasonic imaging apparatus capable of determining the acoustic pressure of ultrasonic waves to be emitted, in consideration of the acoustic pressure distribution of ultrasonic waves in a subject. <P>SOLUTION: The ultrasonic imaging apparatus is adapted to display an MI (mechanical index) value distribution function 62 or a black-and-white gradation scale 63 on a display part 106 so as to be placed side by side with or to be superimposed on tomographic image information 41. An operator therefore acquires, prior to imaging, a region where the acoustic pressure in an imaging region becomes the destructive acoustic pressure of a contrast medium, and eventually makes the region in which the contrast medium is destroyed, coincident with the described position of the contrast medium in the imaging region by resetting a scan parameter value, thereby achieving the efficient, accurate and reliable destruction of the contrast medium. <P>COPYRIGHT: (C)2013,JPO&INPIT |
