<p><P>PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment which adjusts signal range to gradate with a high degree of freedom when replaying and displaying an ultrasonic image signal. <P>SOLUTION: A contrast agent is given to a subject. The crosssection of the subject is scanned by ultrasound. An ultrasonic image signal which is obtained from an obtained echo signal is displayed in real time. In ultrasonic diagnostic equipment which records this ultrasonic image signal on an image memory 15, the ultrasonic image signal is memorized on the image memory 15 in dynamic range wider than the dynamic range of signal range to gradate when displaying an ultrasonic image in real time. The memory 15 is prepared before a scan converter 8 and memorizes the ultrasonic image signal on the preliminary step of scan convert processing by the scan converter 8. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
